Apparatus and method for testing a device

An apparatus for testing a device including a plurality of elements each having contact surface and a non-contact surface, the apparatus comprising a base for holding the device, the base having a contact surface engageable with the contact surface of each element, an actuator, a plurality of compliant members carried by the actuator to engage the non-contact surface of each element, each compliant member further including an aspect ratio of at least 1:1, and means for exerting a force against the actuator, the aspect ratio for allowing the compliant members to compensate for physical variations of the elements, provide compliance between the apparatus and the elements and substantial coplanarity between the contact surface of each element and the contact surface of the base while allowing a sufficient focusing of force by the compliant members against the non-contact surface of each element to provide contact between the contact surface of each element and the contact surface of the base without damaging the elements.
