| Zusammenfassung: | This invention relates to a piston probes which are used in testing microscopic circuits such as those which are in semiconductor chips and multichip interconnect modules.
A test module having a lid to force a chip in contact with the test pads using a bed of nails to conform to the shape of the chip. The lengths of the nails are cut to conform to be of equal length above the chip with different size heads to apply the proper force. A pressurized bag may be placed above the head of nails to apply force to the chip. |
