Abstract:
A test socket interposer, comprising:a horizontal, non-conductive, flexible substrate with a top and bottom surface; a lower ground contact and a lower signal contact on the bottom surface of the substrate, positionable on a test socket with the lower ground contact on a socket ground contact and with the lower signal contact on a socket signal contact; an upper ground contact and an upper signal contact on the top surface of the substrate, the upper signal contact having a surface, at least a portion of which (i) is higher than an upper surface of the ground contact so that a signal contact of a device in a common plane as a device ground contact contacts the upper signal contact before the device ground contact contacts the upper ground contact when the device is moved downward and (ii) is to the right of a lower surface of the lower signal contact so that a downward force exercised by the device signal contact causes pivoting of the upper signal contact that moves the area of contact between the device signal contact and the upper signal contact downward, the substrate being sufficiently compliant to allow for pivoting of the upper signal contact, and for the device ground contact to subsequently contact the upper ground contact; and ground and signal electrical connections, the ground electrical connection linking the upper ground contact with the lower ground contact and the signal electrical connection linking the upper signal contact with the lower signal contact.
