ABSTRACT OF THE DISCLOSURE A probe card apparatus and method which allows reconfiguration of the probing circuits. A first probe card member has a plurality of incomplete probing circuits which are associated with a plurality of contact holes. An adapter ring member, having a plurality of T-shaped conductive lines terminated in contact holes, is removably mounted in close proximity to the first probe card member. Spring-loaded contact pins provide contact between the members such that the T-shaped conductive lines are used to complete the probing circuit. The T shaped conductive lines are severable lines, and discrete electronic components can be connected between respective contact holes. As the adapter ring member is of a removably attachable construction, the entire probe card circuitry is reconfigurable by a simple change of the adaptor ring.
