Best 10 global PCB fiberglass manufacturers

As the core substrate for PCB manufacturing, the three main raw materials for the production of CCL include copper foil, resin and fiberglass cloth. Fiberglass is one of the raw materials of PCB material, which is used to strengthen the part of PCB material, helping to manufacture extremely thin and durable circuit board materials. In this article, we will briefly introduce PCB fiberglass and list best 10 global PCB fiberglass manufacturers.

Introduction of PCB fiberglass

Glass fiber cloth is made of glass balls or waste glass as raw materials, through high-temperature melting, wire drawing, winding, weaving and other processes. Its monofilament has a diameter of a few microns to more than twenty microns, equivalent to 1/20-1/5 of a human hair, and each bundle of fiber precursor is composed of hundreds or even thousands of monofilament.

Glass fiber is an essential basic material for copper-clad laminate (CCL) and printed circuit board (PCB) industry. Its properties largely determine the electrical properties, mechanical properties, dimensional stability and other important properties of CCL and PCB.

Glass fiber is a kind of inorganic nonmetallic material with excellent performance. Its advantages are good insulation, strong heat resistance, good corrosion resistance, high mechanical strength, but the disadvantages are brittle, poor wear resistance.

Glass fiber has many characteristics, as follows:
1. Used for low temperature -196 °C, high temperature between 300 °C, with weather resistance.
2. Non-adhesion, not easy to adhere to any substance.
3. Chemical corrosion resistance, can resist the corrosion of strong acid, strong alkali, aqua regia and various organic solvents.
4. Low friction coefficient, is the best choice for oil-free self-lubrication.
5. The light transmittance reaches 6~13%.
6. It has high insulation performance, anti-ultraviolet and anti-static.
7. High strength. It has good mechanical properties.
8. Drug resistance
