ABSTRACT:
A test contactor for establishing a releasable connection between terminals of an integrated circuit electronic module to be tested and a circuit board connected to test equipment includes a housing carrying a contact element for each terminal of the module. Each contact element includes a contact surface which is engaged by the corresponding terminal of the modules when testing is effected. The contact surface is connected to a pad which connects the contact element to the circuit board by a spring arm that is slidably engaged with the pad. Accordingly, as the contact element is deflected during testing, the spring arm slides along the pad, and the resiliency of the contact element restores itself it is initial condition when the module is removed. The spring arm provides the shortest possible electrical path between the contact surface and the pad, thereby assuring a high frequency response.
