     DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS OF INVENTIVE CONCEPTS 
     Example embodiments of inventive concepts will now be described more fully with reference to the accompanying drawings, in which example embodiments of inventive concepts are shown. The invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the sizes of components may be exaggerated for clarity. 
     It will be understood that when an element or layer is referred to as being “on”, “connected to”, or “coupled to” another element or layer, it can be directly on, connected to, or coupled to the other element or layer or intervening elements or layers that may be present. In contrast, when an element is referred to as being “directly on”, “directly connected to”, or “directly coupled to” another element or layer, there are no intervening elements or layers present. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. 
     It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, components, regions, layers, and/or sections, these elements, components, regions, layers, and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, and/or section from another element, component, region, layer, and/or section. Thus, a first element, component, region, layer, or section discussed below could be termed a second element, component, region, layer, or section without departing from the teachings of example embodiments of inventive concepts. 
     Spatially relative terms, such as “beneath”, “below”, “lower”, “above”, “upper”, and the like, may be used herein for ease of description to describe one element or feature&#39;s relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the exemplary term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. 
     Embodiments described herein will refer to plan views and/or cross-sectional views by way of ideal schematic views. Accordingly, the views may be modified depending on manufacturing technologies and/or tolerances. Therefore, example embodiments of inventive concepts are not limited to those shown in the views, but include modifications in configuration formed on the basis of manufacturing processes. Therefore, regions exemplified in figures have schematic properties and shapes of regions shown in figures exemplify specific shapes or regions of elements, and do not limit example embodiments of inventive concepts. 
     An apparatus according to example embodiments of inventive concepts may perform a reflow of a solder ball  22  provided on a treatment object  1 . The treatment object  1 , for example, may be a printed circuit board  10  on which a semiconductor chip  20  is mounted. The semiconductor chip  20  may be mounted on the printed circuit board  10  via a chip mounting process.  FIG. 1A  illustrates an example of the printed circuit board  10  on which the semiconductor chip  20  is mounted. The printed circuit board  10  may be supplied as a shallow plate shape. Connection terminals  12 , which may be configured to electrically connect the printed circuit board  10  to an external electronic device (not shown), may be formed on one side of the printed circuit board  10 . Connection terminals  14 , e.g. pads, may be formed on a top surface of the printed circuit board  10  to electrically connect the semiconductor chip  20  to the printed circuit board  10 . The connection terminal  12  and the pads  14  may be electrically connected to one another through a plurality of conductive lines (not shown) formed on the printed circuit board  10 . The semiconductor chip  20  may be placed on the printed circuit board  10  so that the solder ball  22  is in contact with the pad  14 . 
     As an alternative, a treatment object  1 ′ may be a semiconductor chip  20 ′ to which a solder ball  22 ′ attaches.

A lengthwise direction of the housing  100  may be disposed along the second direction  64 . The housing  100  may include a front wall  111 , a rear wall  112 , a top wall  113 , a bottom wall  114 , a first sidewall  115 , and a second sidewall  116 . The front wall  111  may face the first unit  40  and the rear wall  112  may face the third unit  60 . An entrance  121  functioning as a path for inputting the printed circuit board  10  to the housing  100  may be formed at the front wall  111  and an exit  122  functioning as a path for outputting the printed circuit board  10  from the housing  100  may be formed at the rear wall  112 . A shutter  142  opening and shutting the entrance  121  may be installed on the front wall  111  and a shutter (not shown) opening and shutting the exit  122  may be installed on the rear wall  112 . Each shutter may be linearly moved in an up and down direction by a cylinder  144 .

An alternating current may be applied to the coil  340  from the power supply  320 . The printed circuit board  10  on which the semiconductor chip  20  may be mounted may be placed on the conveyers  220  and  240  of the input supporter  201 .
