High temperature resistant electronic fiberglass

Electronic Fiber Glass is a key basic source material in electronic information, aerospace and other industries. It appears in almost every electronic component and is spread across all fields of the national economy and national defense industry. Electronic Glass Fiber cloth (referred to as electronic cloth) woven from electronic glass fiber is an essential basic material for the copper clad laminate (CCL) and printed circuit board (PCB) industries. Its performance determines the performance of CCL and PCB to a large extent. Important properties such as electrical properties, mechanical properties, and dimensional stability.

In recent years, the prosperity of electronic information technology has driven the market demand for electronic fiberglass cloth to grow year by year. With the rapid development of the global electronic information industry, multi-layer circuit boards are developing in the direction of high density, high performance and multi-layering, which puts forward higher requirements for electronic glass fiber, which is the key basic material of multi-layer printed circuit boards. , and also provides broad development space for the electronic glass fiber and fabric industry.

After electronic yarn is spun into electronic cloth, it is mainly used in copper-clad laminates. glass yarn is mainly divided into roving and electronic yarn (spun yarn). The single filament diameter of roving yarn is 10-20 microns, and the single filament diameter of electronic yarn is 4-9 microns. Electronic yarn is a relatively high-end product among glass fiber yarns. At present, a complete industrial chain of electronic yarn-electronic cloth-copper clad laminate (CCL)-printed circuit board (PCB) has been formed, in which electronic yarn is woven to form electronic cloth. Electronic cloth is the basic material of copper clad laminate, and copper clad laminate is the base material of PCB. substrate.
