Product Introduction
Printed Circuit Board Sheets FR4 Material Fiberglass Epoxy Sheet Production Description
Printed Circuit Board Sheets FR4 Material Fiberglass Epoxy Sheet is made of the whole shaft of electronic grade fiberglass cloth and impregnated with epoxy resin, then laminated with high temperature and high pressure. It is a hard material and cannot be molded, however it can be machined into different size.
Printed Circuit Board Sheets FR4 Material Fiberglass Epoxy Sheet is a greenish material and has impressive properties. It has a very low coefficient of thermal expansion which means it doesn’t contract or expand a lot with temperature changed, also it doesn’t absorb moisture.
Application in Printed Circuit Board
Printed Circuit Board Sheets FR4 Material Fiberglass Epoxy Sheet has excellent dielectric qualities, low coefficient of thermal expansion and doesn’t absorb moisture which make the material to be a circuit board and widely used for it. Also, the glass fiber present in FR4 sheet makes it extremely strong and the epoxy resin used is generally flame retardant. This makes the entire PCB flame retardant. FR4 sheet offers ease of use from the fabrication point of view. Hence, it provides immense flexibility to the designer, allowing him to utilize the intrinsic properties of the material to the advantage of the application and process.
