CROSS-REFERENCE TO RELATED APPLICATION(S) 
     This application is a continuation patent application of U.S. patent application Ser. No. 15/280,465, filed Sep. 29, 2016 and titled “Multi-Part Electronic Device Housing Having Contiguous Filled Surface,” which is a nonprovisional patent application of and claims the benefit of U.S. Provisional Patent Application No. 62/235,315, filed Sep. 30, 2015 and titled “Multi-Part Electronic Device Housing Having Contiguous Filled Surface,” the disclosures of which are hereby incorporated by reference herein in their entireties. 
    
    
     FIELD 
     The disclosure relates generally to electronic devices and more particularly to a housing for an electronic device that allows electromagnetic waves to pass through the housing. 
     BACKGROUND 
     Conventional electronic devices typically include various communication components that are capable of providing and/or receiving data from other electronic devices. For example, most electronic devices include an antenna that is utilized to send and/or receive data for the electronic device wirelessly. The antenna is typically embedded or positioned within the enclosure or housing of the electronic device to prevent the antenna from being damaged and incapable of sending or receiving data for the electronic device. However, the enclosures or housings for the electronic devices are typically solid (e.g., formed from a single piece) to improve strength for the electronic device, to house and protect the internal components of the electronic device and/or to prevent contaminants (e.g., dust, water and other particles) from entering the housing and damaging the internal components of the electronic device. The solid enclosure and/or housing can negatively impact the operation of the antenna of the electronic device by making it difficult for the electromagnetic waves of the antenna to pass through the housing when sending and/or receiving data. 
     As such, enclosures and/or housings can include breaks or openings to improve the transmission of the electromagnetic waves for the antenna through the housing. However, forming breaks or openings in the housing makes the electronic device and its internal component more susceptible to damage (e.g., ingress for contaminants, weakened component). Additionally, where a distinct component (e.g., door, plug) is positioned within the break or opening, the gap formed therebetween can grow and/or vary in size over the operational life of the electronic device as a result of the coupling between the distinct component and the remainder of the enclosure or housing wearing and/or failing. 
     SUMMARY 
     A housing for an electronic device is disclosed. The housing comprises: a first portion comprising an opening; a second portion positioned within the opening; a protrusion extending into a gap formed between the first portion and the second portion; a first ink layer disposed within the gap and substantially surrounding the protrusion; and a second ink layer disposed within the gap and over the first ink layer; wherein the first portion, second ink layer, and second portion cooperate to form a substantially contiguous surface; and the second ink layer is positioned approximately 5 microns (μm) or less below an exposed surface of the first portion and an exposed surface of the second portion. 
     A method for forming a housing for an electronic device is disclosed. The method comprises coupling an insert to a first portion and a second portion of the housing, extending a protrusion of the insert within a gap between the first portion and second portion; disposing a first ink layer within the gap; curing the first ink layer; disposing a second ink layer within the gap and over the first ink layer, an exposed surface of the first portion, and an exposed surface of the second portion; smoothing at least part of the second ink layer; and curing the second ink layer; wherein a top surface of the second ink layer is within 10 microns of a top surface of the second portion of the housing. 
     An electronic device is disclosed. The electronic device comprises a housing including a body comprising an opening formed in an end of the housing, and an antenna window positioned within the opening of the body. The antenna window is separated from the body via a gap. The electronic device also comprises a plastic insert coupled to the housing and the antenna window. The insert comprises a protrusion extending into a portion of the gap between the housing and the antenna window. Additionally, the electronic device comprises at least one ink layer disposed within the gap. The at least one ink layer is exposed between the housing and the antenna window.

     DETAILED DESCRIPTION 
     Reference will now be made in detail to representative embodiments illustrated in the accompanying drawings. It should be understood that the following descriptions are not intended to limit the embodiments to one preferred embodiment. To the contrary, it is intended to cover alternatives, modifications, and equivalents as can be included within the spirit and scope of the described embodiments as defined by the appended claims. 
     The following disclosure relates generally to electronic devices and more particularly to a housing for an electronic device that allows electromagnetic waves to pass through the housing. 
     In a particular embodiment, a housing for an electronic device is configured to allow electromagnetic waves from an antenna of the electronic device (or other electronic component) to pass through the housing without substantial attenuation or being blocked. The housing includes two distinct portions that are separated by a gap. The gap formed between the first portion and the second portion is sized to allow electromagnetic waves from the antenna to pass through the housing, between the two distinct portions. The gap may be filled by a filler or multiple fillers, which may (or may not) be transparent to antenna frequencies. In some embodiments, an ink, resin, latex, or other suitable material may form a top surface of the filler or fillers such that the top surface is flush or near-flush with the two distinct portions. 
     Components of the housing (e.g., the fillers) are positioned and/or disposed in the gap to provide structure to the housing, prevent the size of the gap from varying over the operational life of the electronic device, and provide a surface between the two portions of the housing that feels contiguous to a user of the housing. In certain embodiments, the user may not be able to tactilely perceive difference in depth and/or height between the housing components and a top surface of a filler in the gap. Further, in some embodiments the fillers improve the appearance of the housing, including the gap. 
     In the particular embodiment, an insert can be coupled to the two portions of the housing for securing the portions to one another and setting the size of the gap formed therebetween. Additionally, a protrusion of the insert can be positioned within the gap to provide additional support and rigidity to the separate portions of the housing. At least one layer of ink can also be disposed within the gap over the protrusion of the insert and can seal the gap between the two portions of the housing. The ink disposed in the gap can be formed such that the surface of the ink is contiguous with or positioned below the surface of the housing by a small distance (e.g., less than approximately 5 microns (μm), 10 microns (μm), or the like), such that the ink in the gap creates a transition between the two portions of the housing that feels contiguous and/or lacks discontinuities that are tactilely and/or visually perceptible. As such, although the housing is formed from two distinct portions, the ink disposed in the gap makes the transition from and/or over the surface of the housing between the two portions tactilely and/or visually imperceptible to a person; in some embodiments, the housing feels continuous, smooth and/or uniform. 
     These and other embodiments are discussed below with reference to  FIGS. 1A-6B . However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these Figures is for explanatory purposes only and should not be construed as limiting. 
       FIG. 1A  shows an electronic device including a housing according to embodiments. The electronic device  100  shown in  FIG. 1A  includes an antenna (not shown) positioned within the housing  102  for transmitting and receiving electromagnetic waves to communicate and/or provide electronic information to other electronic devices wirelessly. In order to transmit and receive electromagnetic waves, a break or separation is formed in housing  102  to allow the electromagnetic waves to pass to and/or from the antenna and through housing  102 . As discussed below in detail, housing  102  includes two distinct parts or portions that allow the electromagnetic waves to pass through housing  102  without disruption or disturbance. The two distinct portions of housing  102  are separated by a gap that is sized to aid in allowing electromagnetic waves from the antenna of electronic device  100  to pass through housing  102 , between the two distinct portions. As discussed herein, components of housing  102  and/or electronic device  100  are positioned and/or disposed within the gap to provide structure to housing  102  and/or prevent the size of the gap from varying during the operational life of electronic device  100 . In addition to providing structural support and benefits, and as discussed herein, additional components can be disposed within the gap formed in housing  102  to make housing  102  feel contiguous and/or lack discontinuities that are tactilely and/or visually perceptible when a user touches and/or looks at housing  102  formed from two distinct portions. 
     As shown in  FIG. 1A , housing  102  of electronic device  100  includes a first portion or a main body portion  104  (hereafter, “body  104 ”). Body  104  of housing  102  includes the majority of the structure or material forming housing  102  for electronic device  100 . In a non-limiting example, body  104  of housing  102  includes and/or houses substantially all of the internal components of electronic device  100 , including the antenna (not shown) for electronic device  100 . Body  104  of housing  102  includes a recess, cutout or opening  106  formed on an end  108  of housing  102 . As shown in  FIG. 1A , and additionally shown in the enlarged portion of electronic device  100  in  FIG. 1B , recess or opening  106  extends into and/or through a substantially small portion of housing  102  at end  108 . Additionally, opening  106  is formed in and/or through only a portion of the width of housing  102  at end  108 . 
     Housing  102  also includes a second portion or an antenna window  110 . As shown in  FIGS. 1A and 1B , antenna window  110  is positioned within opening  106  of body  104 . That is, antenna window  110  is positioned within opening  106  and is at least partially surrounded by body  104  of housing  102 . Antenna window  110  is smaller than opening  106  formed in body  104  at end  108  of housing  102 . As such, when antenna window  110  is inserted and/or positioned within opening  106  formed in body  104 , a separation or gap (G) exists (see,  FIG. 1B ) between body  104  and antenna window  110  of housing  102 . The separation or gap (G) formed between body  104  and antenna window  110  is sized to allow the antenna of electronic device  100  to transmit and/or receive electromagnetic waves through housing  102  and/or between body  104  and antenna window  110 , as discussed herein. The gap is sized by forming opening  106  and/or antenna window  110  to have a predetermined dimension, such that when antenna window  110  is inserted and/or positioned within opening  106 , the gap (G) between body  104  and antenna window  110  exists. Additionally as discussed herein, the gap (G) formed between body  104  and antenna window  110  includes additional components formed therein, where the additional components also aid in the formation of the gap (G) between body  104  and antenna window  110  of housing  102 . 
     Housing  102 , and the distinct portions forming housing  102 , are formed from similar materials or materials having substantially similar properties and characteristics. Specifically, body  104  and antenna window  110  can be formed from similar materials, or alternatively, can be formed from distinct materials. In the non-limiting example where body  104  and antenna window  110  are formed from the same material, body  104  and antenna window  110  can be formed from the same piece of material. That is, a single sheet or piece of material can be formed to take the desired shape of housing  102 , and can be subsequently cut to form opening  106  in body  104 . The removed or cut portion of the material can undergo further material processing (e.g., grinding, cutting, shaping and so on) to form antenna window  110 . Additionally or separately, opening  106  can undergo additional material processing to ensure that antenna window  110  formed from the removed or cut portion of the single piece of material can be positioned within opening  106  and a gap (G) can be formed therebetween. Body  104  and antenna window  110  can be formed from various materials that provide a rigid structure for supporting electronic device  100  and/or protecting the internal components of electronic device  100 , such as, but not limited to, metals or metal alloys. In a non-limiting example, both body  104  and antenna window  110  can be formed from aluminum. In another non-limiting example, one of body  104  or antenna window  110  can be formed from aluminum, and the other component (e.g., body  104 , antenna window  110 ) forming housing  102  can be formed from a distinct metal alloy, such as titanium, chromium or steel. 
       FIG. 2  shows a cross-section view of housing  202  taken along line  2 - 2  in  FIG. 1B . Specifically,  FIG. 2  shows a cross-section of body  204 , antenna window  210  and additional components of housing  202 . It is understood that similarly numbered and/or named components may function in a substantially similar fashion. Redundant explanation of these components has been omitted for clarity. 
     As shown in  FIG. 2 , housing  202  includes an insert  212 . Insert  212  is positioned below, adjacent and/or between body  204  and antenna window  210  of housing  202 . Additionally, insert  212  is coupled or affixed to body  204  and antenna window  210  of housing  202 . Specifically, and as shown in  FIG. 2 , insert  212  is coupled to an interior surface  218  of body  204  and an interior surface  220  of antenna window  210 , respectively. In a non-limiting example, insert  212  is adhered to interior surface  218  of body  204  and interior surface  220  of antenna window  210 , respectively, using adhesive  222 . In addition to adhering and/or coupling insert  212  to body  204  and antenna window  210 , respectively, adhesive  222  can also be configured to seal the gap (G) formed between body  204  and antenna window  210 . The sealing of the gap (G) can prevent contaminants (e.g., water, dust and other damaging particles) from entering housing  202 . It is understood that insert  212  can be coupled to body  204  and antenna window  210  using other coupling mechanisms and/or techniques as well. In non-limiting examples, insert  212  can be coupled to body  204  and antenna window  210  using tape, solder, fasteners (e.g., screws, snap-fits, and so on) and the like. 
     In addition to adhering insert  212  to body  204  and antenna window  210 , adhesive  222  can also act as a shim within housing  202 . Specifically, the thickness and/or amount of adhesive  222  positioned between insert  212  and body  204 /antenna window  210  can create an “offset” and/or a space between insert  212  and body  204 /antenna window  210 . This offset can alter size, and specifically the depth, of the gap (G) formed between body  204  and antenna window  210 . As discussed herein, the depth of the gap (G) formed in housing  202  impacts and/or influences a thickness and/or an amount of ink(s) that can be disposed within the gap (G). Although adhesive  222  is discussed as creating the offset between insert  212  and body  204 /antenna window  210 , it is understood that any coupling component formed between insert  212  and body  204 /antenna window  210  for coupling the components can create and/or influence the offset. 
     Insert  212  also includes a protrusion  224 . Protrusion  224  extends from the portion of insert  212  positioned below and/or coupled to body  204  and antenna window  210 . Additionally, protrusion  224  extends between body  204  and antenna window  210 , and/or is positioned within a portion of the gap (G) formed between body  204  and antenna window  210 . As shown in  FIG. 2 , the positioning of protrusion  224  between body  204  and antenna window  210  impacts and/or influences the size of the gap (G) formed between body  204  and antenna window  210 . Specifically, the gap (G) formed between body  204  and antenna window  210  can be no smaller than protrusion  224  of insert  212 . As a result, protrusion  224  may include a width and/or size that may correspond to the minimum size required for the gap (G) to allow electromagnetic waves from the antenna (not shown) of an electronic device (see,  FIG. 1A ) to pass through housing  202  and/or between body  204  and antenna window  210 , as discussed herein. 
     Additionally as shown in  FIG. 2 , protrusion  224  is positioned below an exposed surface  226  of body  204  and an exposed surface  228  of antenna window  210 . That is, protrusion  224  of insert  212  is positioned below exposed surface  226  of body  204  and exposed surface  228  of antenna window  210 , such that protrusion  224  is not visible in housing  202 . In a non-limiting example, protrusion  224  of insert  212  can be positioned below exposed surface  226  of body  204  and exposed surface  228  of antenna window  210  at a distance between approximately 50 microns (μm) and approximately 200 μm, and/or 5 to 100 microns in particular embodiments. As discussed herein, additional components of housing  202  are positioned within the gap (G) between body  204  and antenna window  210  and/or are disposed over protrusion  224 . In some embodiments, the distance between the protrusion&#39;s top surface and the exposed surface(s) may set a total depth of one or more ink layers or other fillers. 
     As shown in  FIG. 2 , insert  212  including protrusion  224  is formed as a single, integral component or structure. However, it is understood that protrusion  224  can be formed from a distinct piece or component and can be coupled to insert  212  using any of the coupling mechanisms and/or coupling techniques discussed herein. Additionally, insert  212  including protrusion  224  can be formed from a substantially rigid component than can hold body  204  and antenna window  210  in place within housing  202 . In a non-limiting example, insert  212  can be formed from a polymer, such as plastic. 
     Housing  202 , as shown in  FIG. 2 , can also include filler(s) such as a first ink layer  230  disposed within the gap (G) formed between body  204  and antenna window  210 . Additionally, first ink layer  230  is disposed within the gap (G) and substantially surrounds, covers, and/or masks protrusion  224  of insert  212 . As shown in  FIG. 2 , portions of first ink layer  230  are disposed around protrusion  224  of insert  212  and are positioned between body  204  and protrusion  224 , and antenna window  210  and protrusion  224 , respectively. As such, first ink layer  230  can be formed between body  204  and protrusion  224 , and antenna window  210  and protrusion  224 , respectively, to ensure the gap (G) formed between body  204  and antenna window  210  is adequately sized to allow electromagnetic waves to be transmitted through housing  202  and/or the gap (G). Additionally, first ink layer  230  can also be formed or disposed between body  204  and protrusion  224 , and antenna window  210  and protrusion  224 , respectively, to seal the gap (G) of housing  202 . 
     Additionally as shown in  FIG. 2 , first ink layer  230  is positioned below portions of body  204  and antenna window  210 , respectively. Specifically, a surface  232  of first ink layer  230  disposed in the gap (G) formed between body  204  and antenna window  210  is positioned below exposed surface  226  of body  204  and exposed surface  228  of antenna window  210 , respectively. In some embodiments, surface  232  of first ink layer  230  is formed below exposed surface  226  of body  204  and exposed surface  228  of antenna window  210 , respectively, to make additional room within the gap (G) formed between body  204  and antenna window  210  for a second ink layer, although this is not necessary or contemplated in all embodiments. Other embodiments may form the surface  232  at or even above the exposed surfaces  226 ,  228 . 
     First ink layer  230  is formed from a first curable colored ink. The color of the ink forming first ink layer  230  is dependent on, at least in part, the color of body  204  and antenna window  210 . Additionally, the amount of the first curable colored ink forming the first ink layer  230  that is disposed over protrusion  224  is dependent upon the color of the ink. That is, the thickness and/or the amount of curable colored ink disposed within the gap (G) is dependent upon the color of the curable colored ink forming the first ink layer  230  and/or the desired color to be perceived through a second ink layer, as discussed herein. In a non-limiting example, the thickness and/or amount of a curable colored ink forming a black first ink layer  230  can be substantially less than a thickness and/or amount of a curable colored ink forming a light gray first ink layer  230 . The thickness and/or amount of the black ink can be smaller because the black ink is more opaque, and therefore is more true to color and/or requires less color to achieve a desired color (e.g., black) visible and/or perceived in the gap (G) formed in housing  202 . 
     Additionally, by disposing first ink layer  230  formed from colored ink within the gap (G), the visible color of the ink disposed in the gap (G) can be constant, uniform and/or include less variation for housing  202 . That is, because the visible color of the gap (G) formed within housing  202  is directly dependent upon the colored ink forming first ink layer  230  disposed between body  204  and antenna window  210 , the quality and/or consistency of the visible color can be controlled by the amount of ink disposed within the gap (G). In non-limiting examples, the intensity, the consistency/uniformity and/or the variation of the visible color of first ink layer  230  disposed and visible in gap (G) of housing  202  can be improved by altering the amount and/or thickness of first ink layer  230 . 
     Housing  202  can also include second ink layer  234  and, in some embodiments, additional ink layers beyond the second. As shown in  FIG. 2 , second ink layer  234  is disposed and/or formed within the gap (G) formed between body  204  and antenna window  210 , and is formed over and/or surrounding first ink layer  230 . Specifically, second ink layer  234  is disposed, formed directly over and/or substantially covers surface  232  of first ink layer  230 . As similarly discussed herein with respect to first ink layer  230 , second ink layer  234  disposed within the gap (G) formed between body  204  and antenna window  210  can substantially seal the gap (G) formed between body  204  and antenna window  210 . 
     As shown in  FIG. 2 , second ink layer  234  includes an exposed surface  236 , opposite surface  232  of first ink layer  230 , that is positioned in substantially planar alignment with exposed surface  226  of body  204  and exposed surface  228  of antenna window  210 , respectively. In this non-limiting example, second ink layer  234  formed in gap (G) provides a relatively uniform transition between body  204  and antenna window  210  of housing  202 . As one example, because exposed surface  236  (e.g., a top surface of the fillers) is contiguous with exposed surface  226  of body  204  and exposed surface  228  of antenna window  210 , the transition across second ink layer  234  from body  204  to antenna window  210  feels contiguous and/or lacks discontinuities that are typically associated with multi-part structures. Thus, the transition(s) may be tactilely and/or visually imperceptible. 
     In another non-limiting example, discussed below in detail, exposed surface  236  of second ink layer  234  can be positioned at substantially the same level as, or slightly below, exposed surface  226  of body  204  and exposed surface  228  of antenna window  210 , respectively. In the non-limiting example, and as discussed in detail below, exposed surface  236  of second ink layer  234  can be positioned below exposed surface  226  of body  204  and exposed surface  228  of antenna window  210  at a relatively small distance. In some embodiments, this distance is less than approximately 5 microns, while in others it may be less than approximately 10 microns. As a result, second ink layer  234  disposed in the gap (G) creates a transition between body  204  and antenna window  210  that is tactilely and/or visually imperceptible for a user of housing  202 . It should be appreciated that tactile imperceptibility may not be a feature of all embodiments. 
     Second ink layer  234  is formed from a second curable ink. Unlike the first curable colored ink forming first ink layer  230 , the second curable ink forming second ink layer  234  is substantially clear and/or transparent. That is, the second curable ink forming second ink layer  234  is formed to have substantially transparent and/or clear properties. As a result of the transparent or clear properties of the second curable ink forming second ink layer  234 , the first curable colored ink forming first ink layer  230  is visible within the gap (G) through second ink layer  234 . 
     Additionally, the thickness and/or amount of the second curable ink forming second ink layer  234  that is disposed over first ink layer  230  is dependent upon the thickness and/or amount of first ink layer  230  disposed in the gap (G). That is, the thickness and/or the amount of second curable ink disposed within the gap (G) is dependent upon the thickness and/or amount of first ink layer  230  disposed in the gap (G) and the amount of space in the gap that is unoccupied by protrusion  224  and first ink layer  230 . Additionally, the thickness and/or amount of the second curable ink forming second ink layer  234  that is disposed within the gap (G) is dependent on, at least in part, the finish and/or texture to be achieved on exposed surface  236  of second ink layer  234 . That is, the second curable ink forming second ink layer  234  can provide a texture and/or a finish (e.g., gloss, matte, and so on) within the gap (G) formed between body  204  and antenna window  210  of housing  202 . In a non-limiting example, the thinner and/or smaller amount of second ink layer  234  disposed in the gap (G), the less glossy second ink layer  234  and first ink layer  230  will appear in the gap (G). As discussed herein, second ink layer  234  can also act as a protective layer for colored, first ink layer  230  to prevent first ink layer  230  from being removed from the gap (G) and/or prevent the gap (G) from becoming colorless or discontinuous in color. 
     The first curable ink forming first ink layer  230  and the second curable ink forming second ink layer  234  can include similar, unique features that aid in the formation of housing  202 , as discussed herein. In a non-limiting example, both the first curable ink forming first ink layer  230  and the second curable ink forming second ink layer  234  can be formed from a material that does not shrink and/or includes low shrinkage during the curing process for each layer. As discussed herein, the non-shrinkage and/or low shrinkage of first ink layer  230  and second ink layer  234  aids in maintaining a uniform and planar transition over the gap (G) between body  204  and antenna window  210 . 
     Additionally in another non-limiting example, and as discussed herein, both first curable ink forming first ink layer  230  and the second curable ink forming second ink layer  234  can be chemically, materially and/or compositionally configured to bond to other curable ink and insert  212  of housing  202 . Specifically, first curable ink forming first ink layer  230  and the second curable ink forming second ink layer  234  are compositionally configured to bond to other curable ink and insert  212  formed from plastic when each of first ink layer  230  and second ink layer  234  are cured. In addition, first curable ink forming first ink layer  230  and second curable ink forming second ink layer  234  can be chemically, materially and/or compositionally configured to prevent, resist and/or minimize a bond with body  204  and antenna window  210  of housing  202 . As discussed herein, the prevention and/or minimization of the bond formed between first ink layer  230  and second ink layer  234  with body  204  and antenna window  210  allows for easier removal of second ink layer  234  that can be disposed over exposed surface  226  of body  204  and/or exposed surface  228  of antenna window  210 , when forming housing  202 . 
       FIG. 3  depicts an example process for forming a housing for electronic devices. Specifically,  FIG. 3  is a flowchart depicting one example process  300  for forming a housing for an electronic device that allows electromagnetic waves from an antenna of the electronic device to pass through the housing. In some cases, the housing is formed for an electronic device discussed below with respect to  FIGS. 6A and 6B . 
     In operation  302 , an insert is coupled to a first portion or body of a housing and a second portion or antenna window of the housing. The insert is coupled to the body and antenna window, respectively, by adhering the insert to each component of the housing. Specifically, the insert is adhered to an interior surface of the body and adhered to an interior surface of the antenna window, respectively. The interior surface of the body is positioned opposite an exposed surface of the body, and the interior surface of the antenna window is positioned opposite an exposed surface of the antenna window. Coupling the insert to the body and antenna window also includes positioning a protrusion of the insert within at least a portion of a gap formed between the body and the antenna window. The gap formed between the body and the antenna window is sized to allow electromagnetic waves from an antenna to pass through the housing and/or between the body and the antenna window. 
     In operation  304 , a first ink layer is disposed within the gap formed between the body and the antenna window of the housing. The first ink layer is disposed in a portion of the gap formed between the body and the antenna window, and the first ink layer substantially covers the protrusion of the insert positioned in a portion of the gap formed between the body and the antenna window. In addition, disposing the first ink layer within a portion of the gap can include disposing a portion of the first ink layer between the protrusion of the insert and the body and/or the antenna window. Additionally, disposing the first ink layer within the gap can also include forming a surface of the first ink layer below the exposed surface of the body and the exposed surface of the antenna window. The first ink layer is disposed within the gap formed between the body and the antenna window using any suitable technique including, but not limited to, material injection using a needle or syringe, jetting material, digital printing and/or precision spraying. The first ink layer disposed in the gap includes a curable, colored ink. 
     In operation  306 , the first ink layer is cured. Specifically, after the first ink layer is disposed within the gap formed between the body and the antenna (e.g., operation  304 ), the first ink layer undergoes a curing process(es). Curing the first ink layer in operation  306  may also result in the first ink layer shrinking. That is, as a result of performing the curing process on the first ink layer, the first ink layer can shrink in size. However, the chemical and/or material composition of the curable, colored ink forming the first ink layer can be a low and/or minimal shrinkage material. As such, the shrinking of the first ink layer that occurs during the curing process can be substantially minimal and/or negligible. Additionally, curing the first ink layer can include bonding the first ink layer to the protrusion of the insert. That is, as the first ink layer is cured, the first ink layer is also bonded to the protrusion of the insert which the first ink layer substantially covers. 
     In operation  308 , a second ink layer is disposed within the gap formed between the body and the antenna window of the housing. Additionally, the second ink layer is over-disposed and/or printed outside of the gap and onto a portion of the body and the antenna window. As such, the second ink layer is disposed over the first ink layer disposed within the gap, a portion of the exposed surface of the body and a portion of the exposed surface of the antenna window. Additionally, disposing the second ink layer also includes temporarily forming an exposed surface of the second ink layer above and/or onto the exposed surface of the body and the exposed surface of the antenna window. Similar to the first ink layer, the second ink layer is disposed in operation  308  using any suitable technique including, but not limited to, material injection using a needle or syringe, jetting material, digital printing and/or precision spraying. The second ink layer includes and/or is formed from a curable, clear or transparent ink. 
     In operation  310 , at least a part of the second ink layer is removed. Specifically, at least a part of the second ink layer disposed over the first ink layer, the exposed surface of the body and/or the exposed surface of the antenna window is removed. The removal process in operation  310  includes scraping at least a part of the uncured second ink layer from the exposed surface of the body and the exposed surface of the antenna window. The second ink layer is removed or scraped from the housing using an ink removal tool. The ink removal tool includes any suitable tool configured to remove the uncured ink forming the second ink layer including, but not limited to, a blade, a scraper, a flexible removal tool, or the like. 
     In operation  312 , the second ink layer is cured. Specifically, after at least a part of the second ink layer is removed in operation  310 , the second ink layer undergoes a curing process(es). Similar to the first ink layer discussed herein with respect to operation  306 , curing the second ink layer may result in the second ink layer shrinking. However, the chemical and/or material composition of the curable, clear ink forming the second ink layer can be a low and/or minimal shrinkage material, and the second ink layer may only shrink a substantially minimal and/or negligible amount when cured. 
     Additionally, curing the second ink layer can include bonding the second ink layer to the first ink layer formed or disposed within the gap formed between the body and the antenna window of the housing. Curing the second ink layer can also include substantially preventing a bond from forming between the second ink layer and the exposed surface of the body and/or the exposed surface of the antenna window. Specifically, when the second ink layer is cured, the parts of the second ink layer that remain on the body and the antenna window and/or are not removed in operation  310  are prevented from bonding to the exposed surface of the body and/or the antenna window. The bonding to the first ink layer and the prevention of a bond forming on the exposed surfaces of the body and/or antenna window, respectively, is a result of the chemical and/or material composition of the curable clear ink forming the second ink layer and the material forming the first ink layer, the body and the antenna window. 
     In operation  314 , any remaining part of the second ink layer disposed anywhere but within the gap is removed. That is, the remaining parts of the second ink layer disposed over the exposed surface of the body and the exposed surface of the antenna window are removed. By removing these remaining parts, the second ink layer is only disposed and/or positioned within the gap formed between the body and the antenna window. The removal of the remaining parts of the second ink layer in operation  314  includes exposing the remaining part of the cured second ink layer to a solvent (e.g., isopropyl alcohol), and wiping away, smoothing, and/or removing the remaining part of the cured second ink layer dissolved by the solvent. 
       FIGS. 4A-4L  show body  404  and antenna window  410  undergoing the process  300  for forming housing  402  as shown and discussed herein with respect to  FIG. 3 . Specifically,  FIGS. 4A-4L  show front and cross-section end views of the various components forming housing  402  undergoing the process  300  discussed herein. The various components shown in  FIGS. 4A-4L  are substantially similar to those shown and discussed herein with respect to  FIGS. 1A-2 . It is understood that similarly numbered and/or named components may function in a substantially similar fashion. Redundant explanation of these components has been omitted for clarity. 
       FIG. 4A  shows a front view of a portion of body  404  and antenna window  410  according to embodiments. Additionally,  FIG. 4B  shows a cross-section view of body  404  and antenna window  410  of  FIG. 4A , taken along line  4 B- 4 B. As shown in  FIGS. 4A and 4B , antenna window  410  is positioned within opening  406  formed in body  404  such that a gap (G) is formed between body  404  and antenna window  410 . As discussed herein, the gap (G) is formed to allow electromagnetic waves to pass through housing  402  and/or between body  404  and antenna window  410 . 
     Additionally shown in  FIG. 4B , insert  412  is coupled and/or adhered to body  404  and antenna window  410 , respectively. Specifically, insert  412  is adhered to interior surface  418  of body  404  and interior surface  420  of antenna window  410  using adhesive  422 . As a result of coupling and/or adhering insert  412  to body  404  and antenna window  410 , protrusion  424  of insert  412  is positioned within a portion of the gap (G) formed between body  404  and antenna window  410 . As shown in  FIG. 4B , when insert  412  is coupled to body  404  and antenna window  410 , a surface  438  of protrusion  424  is positioned within the gap (G) and below exposed surface  426  of body  404  and exposed surface  428  of antenna window  410 , respectively. 
     The process performed on body  404  and antenna window  410  as shown and discussed herein with respect to  FIGS. 4A and 4B  corresponds to operation  302  of the process  300  shown in  FIG. 3 . 
       FIGS. 4C and 4D  show first ink layer  430  being disposed, provided and/or formed in the gap (G) (see,  FIGS. 4A and 4B ). Specifically, first ink layer  430  is disposed into the gap (G) formed between body  404  and antenna window  410 , and is disposed over protrusion  424  including surface  438  (see,  FIG. 4D ). As shown in  FIG. 4C , first ink layer  430  is disposed within the gap (G) using an ink dispensing component  440 . In a non-limiting example, ink dispensing component  440  is configured as a material injection component using a needle or syringe for disposing first ink layer  430  within the gap (G). In other non-limiting examples, ink dispensing component  440  can include a material jetting component or system, a digital material printing system and/or precision spraying component, all configured to dispose first ink layer  430  within the gap (G) formed between body  404  and antenna window  410 . As discussed herein with respect to  FIG. 2 , first ink layer  430  is formed from a curable, colored ink that includes unique properties, as discussed herein. 
     As shown in  FIG. 4D , first ink layer  430  is disposed within the gap (G) (see,  FIG. 4B ) and substantially surrounds protrusion  424  of insert  412 . Additionally, first ink layer  430  includes a surface  432 A, corresponding to the surface of first ink layer  430  prior to performing a curing process for first ink layer  430 . As shown in  FIG. 4D , surface  432 A is positioned below exposed surface  426  of body  404  and exposed surface  428  of antenna window  410 , respectively. As such, unoccupied or unfilled space within the gap (G) exists between surface  432 A of first ink layer  430  and the exposed surfaces  426 ,  428  of body  404  and antenna window  410 , respectively. 
     Turning to  FIG. 4E , and with comparison to  FIG. 4D , first ink layer  430  is shown after or subsequent to performing a curing process. That is,  FIG. 4E  shows first ink layer  430  after the curable, colored ink forming first ink layer  430  undergoes a curing process. As shown in  FIG. 4E , and with comparison to  FIG. 4D , curing first ink layer  430  results in the shrinkage (and/or other thickness reduction) of first ink layer  430  and the curable, colored material forming first ink layer  430 . The post-cured surface  432 B of first ink layer  430  is positioned below the pre-cured surface  432 A of first ink layer  430 , as discussed herein. The curing process performed on first ink layer  430  can include, but is not limited to, a thermal curing process or an ultraviolet (UV) curing process, and is dependent upon the type of curable ink forming first ink layer  430 . 
     Additionally as a result of performing the curing process, first ink layer  430  is bonded to protrusion  424 . Specifically, first ink layer  430  is bonded to surface  438  of protrusion  424  and the other portions of protrusion  424  which first ink layer  430  contacts. First ink layer  430  is bonded to protrusion  424  as a result of curing first ink layer  430 , the material composition of the curable, colored ink of first ink layer  430  and/or the material composition of protrusion  424  of insert  412 . 
     The process performed on body  404  and antenna window  410  as shown and discussed herein with respect to  FIGS. 4C-4E  corresponds to operations  304  and  306  of the process  300  shown in  FIG. 3 . 
       FIGS. 4F and 4G  show second ink layer  434  disposed in the gap (G) (see,  FIGS. 4A and 4B ) formed between body  404  and antenna window  410 . Additionally as shown in  FIGS. 4F and 4G , second ink layer  434  is over-disposed or printed within the gap (G), and as a result, a portion of second ink layer  434  is disposed over a portion of body  404  and antenna window  410 . Similar to  FIG. 4C , second ink layer  434  is disposed within the gap (G) and on portions of body  404  and antenna window  410  using an ink dispensing component  440 . 
     As shown in  FIG. 4G , a portion of second ink layer  434  is disposed within the gap (G) over surface  432  of first ink layer  430 . Additionally, second ink layer  434  is disposed over exposed surface  426  of body  404  and exposed surface  428  of antenna window  410 , respectively. Second ink layer  434  is disposed over first ink layer  430 , body  404  and antenna window  410  to ensure that the gap (G) formed between body  404  and antenna window  410  is substantially filled, and/or to ensure that first ink layer  430  is substantially protected from damage by second ink layer  434 , as discussed herein. Second ink layer  434  is formed from a curable, clear or transparent ink having unique properties and/or characteristics, as discussed herein with respect to  FIG. 2  and discussed below. 
     The process performed on body  404  and antenna window  410  as shown and discussed herein with respect to  FIGS. 4F and 4G  corresponds to operation  308  of the process  300  shown in  FIG. 3 . 
       FIGS. 4H and 4I  show at least a part of second ink layer  434  removed prior to performing a curing process. Specifically, as shown in  FIG. 4I , at least a part of second ink layer  434  previously disposed over first ink layer  430 , body  404  and antenna window  410  is removed. With comparison to  FIG. 4G , second ink layer  434  (formed over first ink layer  430 , exposed surface  426  of body  404  and exposed surface  428  of antenna window  410 ) has a reduced thickness, as a result of removing a part of second ink layer  434 . The removal of an excess part of second ink layer  434  can be achieved by scraping second ink layer  434  from first ink layer  430 , body  404  and antenna window  410 . As shown in  FIG. 4H , an ink removal tool  442  can be used to remove and/or scrape an excess part of second ink layer  434  to reduce the thickness and/or amount of second ink layer  434  disposed over first ink layer  430 , body  404  and antenna window  410 . In non-limiting examples, ink removal tool  442  can be a blade (e.g., doctor blade), a flexible scraper, or the like that is configured to remove a part of second ink layer  434 . 
     The process performed on body  404  and antenna window  410  as shown and discussed herein with respect to  FIGS. 4H and 4I  corresponds to operation  310  of the process  300  shown in  FIG. 3 . 
       FIG. 4J  shows a cross-section view of housing  402  subsequent to performing a curing process on second ink layer  434  and the curable, transparent or clear ink forming second ink layer  434 . As shown in  FIG. 4J , and with comparison to  FIG. 4I , curing second ink layer  434  results in the shrinkage of second ink layer  434  and the curable, clear ink forming second ink layer  434 . Pre-cured surface  436 A (shown in phantom) and post-cured surface  436 B of second ink layer  434  are shown in  FIG. 4J . The post-cured surface  436 B of second ink layer  434  is positioned below the pre-cured surface  436 A of second ink layer  434  as a result of second ink layer  434  shrinking during the curing process. 
     However, and as discussed herein with respect to  FIG. 2 , second ink layer  434  is formed from a material having low-shrinkage properties and/or characteristics. As a result, the shrinking of second ink layer  434  during the curing process is substantially small and/or negligible. Having low-shrinkage properties and/or characteristics for second ink layer  434  can ensure that second ink layer  434  exposed in housing  402  is not formed substantially below body  404  and antenna window  410 , which would create an undesirable transition between body  404  and antenna window  410  in housing  402 . Specifically, as shown in  FIG. 4J , second ink layer  434  can shrink a minimal amount, such that surface  436 B is positioned below exposed surface  426  of body  404  and exposed surface  428  of antenna window  410  by less than approximately 5 μm in one embodiment. A 5 μm (or smaller) difference in surface separation between surface  436 B of second ink layer  434  and body  404 /antenna window  410  may not be tactilely detectable by a human, as discussed herein. Additionally, more layers can be applied to remediate a thickness loss/shrinkage of the second ink layer. As similarly discussed herein with respect to  FIG. 4E , the curing process performed on second ink layer  434  can include, but is not limited to, a thermal curing process or an ultraviolet (UV) curing process, and is dependent upon the type of curable ink forming first ink layer  430 . 
     Additionally as a result of performing the curing process, second ink layer  434  is bonded to first ink layer  430 . Specifically, second ink layer  434  is bonded to surface  432 B of first ink layer  430 . Second ink layer  434  is bonded to first ink layer  430  as a result of curing second ink layer  434 , the material composition of the curable, clear ink of second ink layer  434  and/or the material composition of the curable, colored ink of first ink layer  430 . 
     Additionally, and for similar reasons, curing second ink layer  434  also results in the prevention of a bond (or formation of a weak bond) being formed between second ink layer  434  and body  404 /antenna window  410 . That is, the material composition of the curable, clear ink of second ink layer  434  and/or the material composition of body  404  and antenna window  410  can prevent second ink layer  434  from bonding (or permit only weakly bonding) to body  404  and antenna window  410 , respectively. As discussed herein with respect to  FIG. 2 , the curable, clear ink forming second ink layer  434  can be compositionally configured to not bond (or bond weakly) with specific types of materials (e.g., metals) when second ink layer  434  undergoes a curing process. Preventing the bond (and/or permitting a weak bond) from being formed between second ink layer  434  and body  404 /antenna window  410  can aid in the removal of second ink layer  434  from body  404  and antenna window  410 , as discussed herein. 
     The process performed on body  404  and antenna window  410  as shown and discussed herein with respect to  FIG. 4J  corresponds to operation  312  of the process  300  shown in  FIG. 3 . 
       FIGS. 4K and 4L  show the remaining part of second ink layer  434  disposed over body  404  and antenna window  410  removed from housing  402 . Specifically, the parts and/or residues of second ink layer  434  that were not previously removed by ink removal tool  442  (see,  FIG. 4H ) prior to curing second ink layer  434  are removed subsequent to performing the curing process on second ink layer  434 . The parts and/or residues of second ink layer  434  removed from exposed surface  426  of body  404  and exposed surface  428  of antenna window  410  are removed using a solvent. Specifically, the parts and/or residues of second ink layer  434  still disposed on body  404  and antenna window  410  are exposed to a solvent. As a result of no bond (or weak bonding) being formed between second ink layer  434  and body  404 /antenna window  410  during the curing process, as discussed above, the solvent can substantially surround and/or penetrate the parts of second ink layer  434  still disposed over body  404  and antenna window  410  and dissolve and/or break down the ink. Subsequent to being exposed to the solvent, second ink layer  434  (and/or its residues) is then removed, scraped or wiped away from the exposed surfaces  426 ,  428  of body  404  and antenna window  410 , respectively, after the solvent substantially dissolves or breaks down second ink layer  434 . In a non-limiting example, the solvent used to remove the parts of cured second ink layer  434  disposed over body  404  and antenna window  410  includes isopropyl alcohol (IPA). However, it is understood that other suitable solvents can be used to remove the cured parts of second ink layer  434  from body  404  and antenna window  410 . Additionally, the second ink layer residues can first be removed with a tape, followed by wiping with a solvent. 
       FIG. 4L  shows housing  402  as a final product that can be implemented for use with an electronic device, as discussed herein. As shown in  FIG. 4L , and as discussed herein with respect to  FIG. 2 , second ink layer  434  is formed over first ink layer  430  to protect first ink layer  430  and/or prevent first ink layer  430  from being directly exposed within housing  402 . Additionally, because second ink layer  434  is formed from a clear or transparent ink, and first ink layer  430  is formed from a colored ink, the colored ink of first ink layer  430  is visible in housing  402  through second ink layer  434 . 
     Additionally as shown in  FIG. 4L , and as previously discussed herein with respect to  FIG. 4J , exposed surface  436  of second ink layer  434  is positioned below exposed surface  426  of body  404  and exposed surface  428  of antenna window  410 , respectively. However, because second ink layer  434  has a low-shrinkage chemical and/or material composition, exposed surface  36  is only positioned below exposed surface  426  of body  404  and exposed surface  428  of antenna window  410  a distance of approximately 5 μm. In this embodiment, the distance in which exposed surface  436  is positioned below exposed surface  426  of body  404  and exposed surface  428  of antenna window  410  is sufficiently small that user of housing  402  may not tactilely perceive the transition between body  404 , antenna window  410  and second ink layer  434  positioned in the gap (G) therebetween. As such, although housing  402  is formed from distinct portions (e.g., body  404 , antenna window  410 ), second ink layer  434  disposed in the gap (G) makes the transition from and/or over the surface of housing  202  feel contiguous. As such, the structural discontinuities of housing  202  are tactilely and/or visually imperceptible to a user of housing  202 , although this may not be true in all embodiments and there is no requirement that any embodiment have a tactile imperceptibility, a visual imperceptibility, or both at a gap or transition. 
     The process performed on body  404  and antenna window  410  as shown and discussed herein with respect to  FIGS. 4K and 4L  corresponds to operation  314  of the process  300  shown in  FIG. 3 . 
       FIG. 5  shows housing  502  according to an additional embodiment. Housing  502  includes substantially similar components and portions as discussed herein with respect to  FIGS. 1A-2 and 4A-4L . Redundant explanation of these components is omitted for clarity. 
     As shown in  FIG. 5 , insert  512  is coupled and/or adhered to body  504  and antenna window  510 , and includes protrusion  524  extending into a portion of the gap (G) (see,  FIG. 2 ) formed between body  504  and antenna window  510 , as similarly discussed herein. However, as opposed to certain of the inserts discussed herein, insert  512  includes a predetermined or desired color. Similar to first ink layer  230  discussed herein with respect to  FIG. 2 , insert  512  includes a desired color that substantially matches and/or corresponds to the color of body  504  and antenna window  510 . As discussed herein, the desired color of insert  512  is visible in the gap (G) formed in housing  502 . 
     Housing  502  only includes a single ink layer  544  disposed within the gap (G) formed between body  504  and antenna window  510 . As shown in  FIG. 5 , and similarly discussed herein, single ink layer  544  is disposed within the gap (G) and is disposed over and/or covers insert  512 . Additionally, single ink layer  544  includes an exposed surface  546  positioned adjacent and/or minimally (e.g., less than 5 μm) below exposed surface  526  of body  504  and exposed surface  528  of antenna window  510 , respectively. Single ink layer  544  is formed from a curable, clear or transparent ink, similar to the ink forming second ink layer  234  discussed herein with respect to  FIG. 2 . As a result of forming single ink layer  544  from a clear or transparent ink, the color of insert  512  is visible in the gap (G) of housing  502 , through single ink layer  544 . 
       FIGS. 6A and 6B  show front and back views of an electronic device  600  that utilizes housing  602 , as discussed herein with respect to  FIGS. 1A-5 . Specifically, electronic device  600  includes housing  602  including body  604 , antenna window  610  and a gap (G) (see,  FIG. 1B ) formed between body  604  and antenna window  610  at an end  608  of housing  602 . The gap (G) is sized to allow electromagnetic waves of an antenna (not shown) to be transmitted through housing  602  and/or between body  604  and antenna window  610 . As shown in  FIG. 6 , electronic device  600  is implemented as a tablet computing device. Other embodiments can implement electronic device  600  differently, such as, for example, a mobile phone, a laptop or desktop computer, a gaming device, a display, a digital music player, a wearable computing device or display, a health monitoring device, and so on. 
     Electronic device  600  includes a housing  602  at least partially surrounding a display module, a cover  646  substantially covering the display module and one or more buttons or input devices  648 . Housing  602  can form an outer surface or partial outer surface and protective case for the internal components of the electronic device  600  and at least partially surrounds the display module positioned within an internal cavity formed by housing  602 . Housing  602  can be formed of one or more components operably connected together, such as a front piece and a back piece (not shown). Alternatively, housing  602  can be formed of a single piece operably connected to the display module. Housing  602  is formed from the ceramic material discussed herein, and as a result, undergoes the proof testing process using the testing system prior to being implemented in and/or forming a portion of electronic device  600 . 
     The display module is substantially surrounded by housing  602  and/or is positioned within an internal cavity formed by housing  602 , such that the display module is substantially protected on almost all sides by housing  602 . Cover  646  also protects the display module of electronic device  600 . Specifically, cover  646  is formed integral with and/or is coupled to housing  602  to substantially cover and protect the display module. Cover  646  covers at least a portion of the front surface of electronic device  600 . When a user interacts with the display module of electronic device  600 , the user touches or contacts cover  646 . Similar to housing  602 , cover  646  of electronic device  600  can be a brittle component and is therefore formed from the ceramic material discussed herein. The ceramic material forming cover  646  can undergo the proof testing process performed by the testing system discussed herein with respect to  FIGS. 1A-6B . By performing the proof testing process on the ceramic material forming cover  646 , it is ensured that the ceramic material forming cover  646  meets the quality and/or strength standard required for implementation within electronic device  600  and/or cover  646  and includes desired functional, operational and/or physical characteristics and properties. 
     Button  648  can take the form of a home button, which may be a mechanical button, a soft button (e.g., a button that does not physically move but still accepts inputs), an icon or image on a display, and so on. Further, in some embodiments, button  648  can be integrated as part of cover  646  of the electronic device  600 . Button  648 , like housing  602  and cover  646 , is a brittle component of electronic device  600  and, as a result, is formed from the ceramic material that undergoes the proof testing process as discussed herein.
