摘要
An electrical Kelvin contact assembly for testing IC testing apparatus that uses an assembly design that reduces the tolerance to a near negligible range. The assembly does not use any screws, dowel pins, adhesives or welding to fasten the electrical contacts to the housing. The design of the assembly uses rows of contacts with specially designed protrusions that sit snugly in openings located on three plate-like layers. These layers contain the contacts in the horizontal plane by securing the protrusions in the opening, as well as in the vertical plane by means of a sandwich between three separate layers. A second contact is slid into back slits formed by the three layers.
