ABSTRACT:
A method and apparatus are provided for mounting a circuit component such as a gate array device 12 on a printed circuit board 14. The component 12 may include a plurality of pin-type electrical contacts 18 wherein a first portion of the pin-type contacts 18 have been replaced by button-type contacts. In one embodiment, at least two of the pin-type contacts 22, 24 have been retained and serve the dual purpose of locating the gate array device 12 on the printed circuit board 14 and attaching the gate array device 12 to the printed circuit board 14. A sheet of boron nitride 26 is positioned between the printed circuit board 14 and the circuit component, e.g., the gate array device 12. The sheet of boron nitride 26 includes a plurality of openings extending therethrough in a pattern corresponding to the pattern of electrical contacts 18 on the gate array device 12. The openings 32 in the sheet of boron nitride 26 that correspond to the button-type contacts have resilient electrical contacts 34 disposed therein. The printed circuit board 14 includes a plurality of pad-type contacts 40 disposed on a surface thereof in a pattern corresponding to the button-type contacts of the gate array device 12.
