What Makes Probe Card PCBs Unique A Probe Card PCB is not a typical circuit board—it is a high-precision interface platform used in semiconductor wafer testing. It connects test equipment (ATE) to microscopic pads on silicon wafers through probe needles or MEMS structures. Unlike standard PCBs, probe card boards must support: Ultra-fine pitch interconnections High...
Before a semiconductor chip ever reaches packaging, it must first prove itself on the wafer. Engineers run electrical tests directly on the silicon to identify defective dies early in the manufacturing process. This delicate operation relies on a specialized testing interface known as a Probe Card. At the heart of this system lies the Probe...
