Wus Printed Circuit sees turnaround on high-end PCB demand

Wus Printed Circuit’s strategic pivot toward high-end HDI and substrate-level PCBs is a direct response to surging AI server demand. This move will intensify procurement pressure on upstream ABF film suppliers and laser drilling equipment vendors, while forcing downstream OSATs to accelerate adoption of 2.5D/3D packaging. However, tightening U.S. export controls on advanced packaging could inflate compliance costs for non-Taiwan, China fabs—especially as the U.S.-Mexico-India supply triangle remains immature. Competing against Unimicron and Ibiden’s entrenched CoWoS substrate dominance, Wus must achieve yield breakthroughs within 18 months or risk exclusion from Tier-1 AI chipmaker qualification lists. Over the next 24 months, the AI compute arms race will sustain ABF substrate shortages, but any material progress in CPO or silicon photonics could abruptly erode the premium PCB window—making this transition a race against an impending architectural shift.
