What is a Probe Card PCB? A Probe Card PCB is a high-precision printed circuit board used as the core platform in probe cards for semiconductor wafer testing. It provides the electrical interface between the test system (ATE) and the wafer through probe needles or MEMS structures. Unlike standard PCBs, a Probe Card PCB must...
What is a Fine Line PCB? A Fine Line PCB refers to a printed circuit board with extremely narrow trace width and spacing, typically below 100 μm (4 mil) and often reaching 50 μm (2 mil) or less in advanced designs. These PCBs are essential for high-density interconnect (HDI) and miniaturized electronic products, where space...
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...
In modern digital electronics, ensuring that circuits function correctly before mass production is essential. Logic Test PCBs are specialized printed circuit boards designed to validate the functionality of digital systems, identify defects, and verify signal logic.
