Probe Card Assembly PCB: High-Density PCBs for Semiconductor Wafer Testing
In semiconductor manufacturing, probe cards play a critical role in wafer testing before packaging. The Probe Card Assembly PCB is the core structural and electrical platform that integrates probes, connectors, and signal routing. Its quality directly impacts test accuracy, yield rate, and overall production efficiency. Due to extremely fine pitches, high-frequency signals, and strict impedance...
