In recent years, semiconductor test platforms have rapidly advanced toward high-frequency operation, multi-module integration, and thermal cycling validation. With the rise of mmWave, RF, and chiplet architectures, the associated test PCBs (load boards) are facing new des...
The complexity and electrical requirements of probe card design can be realized by PWB technology. Relying on the impedance control achieved by highly accurate and equal-length line layout, the accuracy of transmission time is improved with low signal interference.
