Patent ID: 7874216

Claim:
A method of mounting a leadless semiconductor chip on a header, said semiconductor chip having leadless contacts on a surface and having a specified geometric shape, said header having a contact surface for receiving said semiconductor chip with said contact surface of said header containing header contact pins, which have to contact said semiconductor chip contacts when said chip is accommodated by said header, comprising the steps of: placing a guide pin on said contact surface of said header with said guide pin extending from said contact surface; forming a guide plate having a chip accommodating aperture of said specified geometric shape and adapted to receive said semiconductor chip, said guide plate having a guide aperture remote from said chip accommodating aperture and dimensioned to receive said guide pin; placing said guide plate on said contact surface of said header by placing said guide aperture over said guide pin to enable said guide plate to be positioned on said header contact surface, wherein said chip accommodating aperture surrounds said header contact pins; and placing said chip in said chip accommodating aperture whereby said chip contacts make direct contact with said header contact pins.
