2 Layer FR4 TG 135 Blue Soldermask 1.6mm PCB Board 35um Copper HASL Lead Free

Linked Electronics Co., Limited is a PCB manufacture in China which focusing on PCB prototypes, high mix PCB production, aluminum PCB and quick turn PCB board.

The substrate most commonly used in printed circuit boards is a glass fiber reinforced (fiberglass) epoxy resin, that is FR4 material, with a copper foil bonded on to one or both sides. PCBs made from paper reinforced phenolic resin, that is CEM1, with a bonded copper foil are less expensive and are often used in household electrical devices. With the development of the electronic products, more and more products use FR4 material instead of CEM1 material.

Tg means Glass Transition Temperature. For standard PCB, that is TG130, or TG135. High TG material is TG170, which is used in communication products. When the working temperature reaches the melting point, that means the temperature exceeds the Tg value, the status of PCB material will be changed from glassy to liquid, which will destroy the function of PCB board.
