ABSTRACT:
A high speed test fixture for testing printed circuit board (PCB)-mounted high speed pin grid array (PGA) chips attaches to the solder side (underside) of the PCB to eliminate the need for lead-lengthening adapter sockets. As a result, the testing can be conducted at the actual chip operating speed with reduced noise, rather than at slower speeds required by "noisy" prior art approaches.
