Copper Clad Laminated Sheet

Copper clad laminated sheet uses glass fiber cloth as substrate material. After being immersed with epoxy resin and then baked into prepreg sheet, several prepreg sheets are then coated with copper foil on one side or both sides, and CCL is finally formed by hot pressing and curing.

FR-4 copper clad laminated sheet has excellent thermal stability and machinability, widely used in the manufacture of printed circuit board (PCB) for television sets, computers, communications equipment and other electronic products.

Product Introduction

CNC fiberglass sheet is a kind of laminated sheet formed through heat pressing after the electric industry fiberglass cloth dips into epoxy resin.Suitable as the mechanical, electric and electronic insulation structural components which are used under homoeothermy and middle temperatures with a certain mechanical performance and electric performance.
The surface of laminated board should be flat and smooth, no bubble, no wrinkle, no delamination or crackle, and properly free from other defects such as scrape, impress, dirty spot and uneven color, but a little color patches is allowed.
