May 18, 2017

Characteristics

FR-4 Epoxy Fiberglass cloth plate is a kind of substrate with epoxy resin as adhesive and electronic grade glass fiber fabric as reinforcement material. Its adhesive and inner core thin copper clad laminate is an important substrate for producing multilayer printed circuit boards.

Performance

The mechanical properties, dimensional stability, impact resistance and humidity resistance of epoxy fiberglass cloth plate are higher than that of paper substrate. Its electrical performance is good, the working temperature is high, its own performance is affected by the environment small. In the processing technology, compared with other resin glass fiber cloth board has great superiority. This kind of product is mainly used for double-sided PCB, the dosage is very large.

Application

Epoxy fiberglass cloth plate, the most widely used product model for FR-4, due to the installation of electronic products and PCB technology development needs, and the emergence of high TG FR-4 products.
