Abstract
A method of probing an electrical device using a membrane probing system having an improved contact. A membrane probe forms a contact having a ridge with a pair of inclined surfaces defining an acute angle such that, when pressed into an electrical pad of a device to be tested, the ridge penetrates into the electrical pad, shearing away any oxide on the surface of the pad. The device may then be tested.
