DIGITIMES Insights: AI server PCB upgrades drive explosive demand for advanced backdrilling equipment
What happened
DIGITIMES observes that as AI servers and high-speed networking equipment continuously pursue higher data transmission rates, printed circuit boards (PCBs) are being upgraded through higher layer counts and lower-loss materials. In this transition, via structures have become critical bottlenecks affecting signal integrity: when high-frequency signals route between layers in a multilayer board, residual barrel copper can impair transmission, generating robust demand for high-precision backdrilling equipment.
