Patent ID: 8535956

Claim:
A method of connecting pins on a lower surface of an integrated circuit chip with pads on an upper surface of a chip carrier, comprising: placing a frame block above the upper surface of the chip carrier, the frame block having a socket opening defining two alignment edges forming a reference corner, the socket opening being larger than the integrated circuit chip and located such that the pads are accessible through the socket opening when the frame block is so placed above the upper surface of the chip carrier, and the frame block being movable in at least first and second non-parallel directions along the upper surface of the chip carrier; lowering the integrated circuit chip into the socket opening until the lower surface of the integrated circuit chip rests on the upper surface of the chip carrier; inclining the chip carrier while it supports the frame block and integrated circuit chip until the integrated circuit chip moves under force of gravity toward the reference corner to abut the alignment edges of the socket opening; and adjusting the position of the frame block by moving it in the first direction and moving it in the second direction, until the pins are aligned with the pads.
