Abstract

A contactor having an internal air gap (5a, 5b) which provides the lowest dielectric constant is provided to be capable of improving signal integrity electrical performance of a test contactor. Resultantly, the present invention reduces the possibilities of impedance mismatch during signal transmission thereby improving insertion loss and return loss of the signal pins.

Description

technical field [0001] The present invention relates to those devices for testing electronic components, and more particularly to a contactor device having multiple internal air gaps which improves signal integrity in the electrical performance of a test contactor. Background technique [0002] A conventional contactor usually includes multiple spring probes, so these contactors are classified as spring probe contactors. Double-ended spring probes, referred to herein as spring probes known in the art, typically provide a shaft with a compressible portion at each end of the shaft. Therefore, when there are multiple spring detectors on a contactor, multiple pins on the contactor or other contactor components such as C4 solder balls will compress the contactor, and these spring detectors will make the contactor on the DUT board Electrical contact is made between each probe and a different electrical contact pin, or between the contact element and a different electrical contact...
