发明名称 Probe contact system having planarity adjustment mechanism
摘要 A probe contact system is capable of adjusting distances between tips of the contactors and contact targets with simple and low cost mechanism. The probe contact system includes a contact substrate having a large number of contactors, a probe card for fixedly mounting the contact substrate for establishing electrical communication between the contactors and a test system, a stiffener made of rigid material for fixedly mounting and reinforcing the probe card, a probe card ring attached to a frame of the probe contact system for mechanically coupling the probe card to the frame, and a plurality of adjustment members for up/down moving the stiffener relative to the probe card ring at three or more locations so that a gap between the probe card and the probe card ring can be altered.
