Test Clips - IC are specialized electrical connectors designed to establish temporary connections between integrated circuits (ICs) and testing equipment. These clips enable signal transmission, power delivery, and data acquisition during semiconductor device validation and quality assurance processes. Their importance lies in ensuring reliable electrical contact without damaging sensitive IC packages, which is critical for precision measurements in electronics manufacturing and R&D.
