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.

FAQ
Q1: What is a double-sided PCB?
A board with copper layers on both sides, connected by plated through-holes, allowing routing on two levels.
Q2: What is the minimum hole size?
Mechanical drilling down to 0.1 mm.
Q3: What surface finishes are available for 2 layer boards?
HASL, lead-free HASL, ENIG, Im Sn, Im Ag, OSP, and ENIG + OSP.
Q4: Can double-sided boards use heavy copper?
Yes, copper weights up to 6 oz are available.
Q5: What is the standard lead time?
3–5 working days for prototypes and batches, after file review is complete.
