Double Layers PCB

Double layers PCB Description

Double layers PCB is the most common but very important PCB in the electronic market, its technology is simple, but the use is very wide, it can be use in communication, equipment, and computer,.etc.

The common surface finish for 2 layers PCB is HAL and immersion gold.For HAL, the surface looks good, the pads are slivery, it’s easily for soldering, and price is cheaper. For immersion gold, the quality is much stable, and the price is expensive than HAL.

The normal material for 2 layers PCB is FR4, and there are also high TG material and aluminium can be chose according to different use.

Two layers PCB prototype and volume production are both welcomed from Polaris. Here you can get competitive price and high quality and fast delivery.
