Abstract

The invention relates to a contact probe and socket for testing semiconductor chips. The contact probe for testing semiconductor chips, comprises: a nonconductive elastic plate having main through-holes corresponding to contact terminals of a test target; plungers coupled on upper sides of the main through-holes, each having a plunger head that is elastically supported by the elastic plate and a plunger body that extends downwards from a center of the plunger head; and contact pins coupled on lower sides of the main through-holes, each having a receiving hole contacting the plunger body of each plunger at a center thereof. Thus, the contact probe employs a simple structure capable of coupling the plungers to the nonconductive elastic plate and elastically supporting the plungers, so that they can be easily manufactured, improve the signal pass of test electric current to secure test reliability, and be manufactured at a subminiature size suitable for equipment for testing semiconductor chips, which are gradually becoming complicated due to technical development.

Description

technical field [0001] The invention relates to a test probe device, in particular to a semiconductor chip test probe device and a test socket which are combined with an elastic plate made of non-conductive material and a plunger. Background technique [0002] The chip is an integrated circuit that performs various functions through the logic elements on the surface of the thin and small engraved board, and the electrical signals from the printed circuit board are transmitted through the bus (Bus) to perform the above functions. [0003] Generally speaking, there are many chips installed in various electronic products, and these chips are enough to determine the performance of electronic products. [0004] A printed circuit board (PCB: printed circuit board) is formed by using conductive copper to form circuit wiring on a thin substrate made of an insulator such as epoxy or phenolic resin and coating it. Integrated circuits, resistors or Electrical components such as switch...
