Glass fiber advantages

Recently, in the forum for electrical insulating materials, people have been asked about the advantages of fiberglass fr4. As a professional insulation material manufacturer and supplier staff, it is natural to say something about this issue. Here is what I learned about this question.

First of all, we must know what is fiberglass fr4? Glass fiber FR-4 is a type of substrate using epoxy resin as a binder and electronic grade glass fiber cloth as a reinforcing material. Its adhesive sheet and core thin copper clad laminate are important substrates for making multilayer printed circuit boards.

Glass fiber fr4 is a grade of flame-resistant material. It means a material specification that the resin material must extinguish itself after combustion. It is not a material name, but a material grade, so at present There are many types of fr4 grade materials used in general circuit boards, but most of them are compounded by so-called Tera-Function epoxy resin plus filler and glass fiber material.

Then, let’s talk about what is the advantage of fiberglass fr4? Glass fiber fr4 has higher mechanical properties, dimensional stability, impact resistance, and moisture resistance than paper substrates. Its excellent electrical performance, high operating temperature, its performance is affected by the environment. In the processing technology, it has a great advantage over other resin glass cloth substrates. This type of product is mainly used for double-sided PCBs, with a large amount. Epoxy glass fiber cloth substrate, the most widely used product model for the fr4, in recent years due to electronic product installation technology and PCB technology development needs, there have been high TgĀ fr4 products.

Do not know who read the article now, have a better understanding of the advantages of fiberglass fr4. If you think that my sharing is helpful to you, please continue to follow us.
