Custom Double Sided PCB with 0.1 mm Drilling, 3/3 mil Trace, and 6 oz Copper for Industrial Applications

Custom Double Sided PCB (2 Layer PCB)

Huayihai fabricates custom double-sided PCBs (2 layer boards) according to customer Gerber files and technical specifications. Double-sided boards remain the workhorse of industrial and consumer electronics, and Huayihai builds them with the same process discipline as its multilayer production.

With 0.1 mm minimum mechanical drilling, 3/3 mil trace capability, and a full range of surface finishes, Huayihai double-sided PCBs serve both prototype runs and stable volume production under IPC-A-600 workmanship standards.

Custom Manufacturing Only

We fabricate double-sided PCBs according to customer Gerber files and technical specifications. We do not supply ready-made or standard stock boards.

Product Specifications
