Printed circuit board test fixture having interchangeable card personalizers

摘要

A printed circuit board test fixture having interchangeable top plates (card personalizers). The test fixture is provided with a vacuum well having a field of probes mounted therein. The field of probes corresponds to the sum of all test points of a family of different printed circuit boards. Only a portion of all the probes are necessary to test any particular type of circuit board of the family. The top plate for each type of circuit board in the family has holes drilled completely therethrough only at locations where selected probes must pass through the top plate in order to contact the test points on the circuit board. In a preferred form, each top plate is partially drilled therethrough to form sockets at locations corresponding to the remaining probes which need not contact a particular circuit board. A hinged cover is provided for the vacuum well to allow easy removal and insertion of top plates.
