in China, can provide customers with single-sided PCB, double-sided FR4 PCB, metal core PCB, heavy copper PCB, rigid PCB and rigid-flex PCB. It provide pcb board, single layer pcb,

The most commonly used thickness of copper foil is 35μm. The use of that in China is generally from 35 to 50μm while there are also thinner ones than this such as 10μm and 18μm and thicker ones than this such as 70μm. The thickness of copper foil on 1 ~ 3mm thick substrate is about 35μm; that on less 1 mm 18μm and that more than 5mm 55μm.

The highest number of layers:

Base material copper foil thickness

FR-4, CEM-3, CEM-1, 94HB, 94VO, polytetrachloroethylene, polyester, polyamide.

Drilling hole: minimum hole diameter 0.15mm

Wire spacing: minimum spacing: gold plate 0.075mm, tin plate 0.10mm

Milling plate: minimum distance from the line to edge: 0.15mm; minimum distance from hole to edge: 0.2mm; minimum profile tolerance: ±0.12mm

Soldering resistance: 85-105℃ / 280℃-360℃
