High Multi-Layer PCB

Multi-layer is the volume backbone — 30 SKUs from 6-layer commercial through 100-layer ATE tester boards. Most North American and Japanese buyers come here for AI server backplanes, optical-module PCBs and high-port-count switches where the layer count keeps climbing. FQC's stack supports up to 100 layers with back-drilling, mixed-dielectric constructions and tight impedance control, all on the same Thai-origin certificate. This is where the China+1 conversation gets concrete: same DFM, same press cycles, no PCT 301 exposure.
