ABSTRACT:
A test fixture having a planar array of spring-loaded contact probes of sufficient number and arrangement to accommodate circuit boards having different patterns of test points. A personalizing board is provided for each different test point pattern and contains partially drilled holes corresponding to probes which are not required for the test point pattern of its corresponding circuit board and completely drilled holes corresponding to probes which are required by the test point pattern. In operation, a personalizing board is mechanically forced against the array of probes so as to cause the probes in the partially drilled holes which are not needed to be depressed, while leaving the required probes in the completely drilled holes undepressed. The vacuum which is used to force the circuit board against the probes thus need depress only the required probes.
