Abstract:
A method of assembling a peripheral device printed circuit board package having first and second electrically conductive covers made of a first metallic material, and first and second electrically conductive frames made of a second metallic material, each of the first and second electrically conductive covers having a perimeter, the method comprising the steps of:placing the second metallic material into a molding machine;converting the second metallic material to a thixotropic state;transferring a first amount of the second metallic material in the thixotropic state to a first mold where the first amount of the second metallic material flows around a portion of the perimeter of the first electrically conductive cover so as to form the first electrically conductive frame attached to the perimeter of the first electrically conductive cover, where the first electrically conductive cover is electrically connected to the first electrically conductive frame;transferring a second amount of the second metallic material in the thixotropic state to a second mold where the second amount of the second metallic material flows around a portion of the perimeter of the second electrically conductive cover so as to form the second electrically conductive frame attached to the perimeter of the second electrically conductive cover, where the second electrically conductive cover is electrically connected to the second electrically conductive frame; andbonding the first electrically conductive frame to the second electrically conductive frame, where the first electrically conductive frame is electrically connected to the second electrically conductive frame, and wherein, when the first frame is bonded to the second frame, the first and second covers do not physically contact each other.
