Abstract
A test adapter for a chip carrier having leads along the four side edges thereof. The adapter comprises an inner housing having latches on its corners which engage the undersides of the corners of the carrier body to retain the adapter thereon. The adapter also includes an outer housing on which the test contacts are mounted. The outer housing is pushed downwardly to cause the contacts to engage the carrier chip leads with a positive wiping action.
Claims17
A test adapter for a chip carrier having leads along the four side edges of the insulative body of the carrier and mounted on a printed circuit board comprising:
- a rectangular housing containing a plurality of test contacts arranged in a pattern to engage exterior portions of said chip carrier leads which extend between the carrier body and the printed circuit board along said four side edges when said housing is mounted over said carrier;
- and
- latching means mounted on at least two diagonally opposed corners of said housing adapted to engage the underside of said carrier body at the corners thereof and between the carrier body and the printed circuit board to retain the test adapter on the carrier.
A test adapter for a chip carrier having leads along the four side edges of the insulative body of the carrier and mounted on a printed circuit board comprising:
- inner and outer housings;
- said outer housing being a generally rectangular frame defined by four walls and mounted on and substantially surrounding said inner housing;
- test contacts carried by said four walls arranged to engage said chip carrier leads when said housings are mounted over said carrier;
- latching means on said inner housing dapted to engage the underside of said carrier between the carrier body and the printed circuit board to retain the test adapter thereon;
- and
- said outer housing being movable downwardly relative to said inner housing to cause said test contacts to engage said chip carrier leads which extend between the carrier body and the printed circuit board with a positive wiping action.
A test adapter for a square chip carrier having leads along the four side edges of the insulative body of the carrier and mounted on a printed circuit board comprising:
- generally square inner and outer housing;
- said outer housing mounted on and substantially surrounding said inner housing;
- test contacts carried by the four walls of said outer housing;
- means on said inner housing for precisely locating said inner housing on said carrier body so that the test contacts on said outer housing are aligned with the chip carrier leads;
- latching means on the corners of said inner housing adapted to engage the underside of said carrier body between the carrier body and the printed circuit board at corresponding corners thereof to retain the test adapter on the carrier;
- said outer housing being movable downwardly to a predetermined position relative to said inner housing to cause a wiping engagement of said test contacts with said chip carrier leads;
- and
- means for releasably holding said outer housing in said predetermined position.
