How does FR4 G10 glass fibre sheet epoxy plate fibreglass manufacturer control the quality?

FR4 glass fibre sheet epoxy plate fibreglass itself has the good insulation performance, mainly used as insulating materials at present. The quality of FR4 epoxy plate is a relatively concerned issue for consumers. Now the current FR4 G10 insulation sheet manufacturer is numerous, the product quality is uneven, so everyone should pay attention to distinguish carefully when choosing, the following FR4 G10 glass fibre sheet epoxy plate fibreglass manufacturer ZTelec Group will teach you how to identify its quality.

1. The more obviously the insulation board is stratified, the more unqualified the quality is.

If you can feel it is a whole, the quality is qualified.

2. Permittivity: it is a measure to the conductivity of a parameter. The greater the dielectric constant of the material is, the current will be more under the same conditions, the worse the insulation performance of the material will be. Therefore, in order to ensure FR4 G10 glass fibre sheet epoxy plate fibreglass can have good insulation, it is very important to maintain its dielectric constant to a certain extent.

3. Resistance: this is one of the main indicators to judge insulation performance of FR4 insulation sheet. The volume of insulation products is strictly regulated. According to different use needs, there are different volume standards. Generally speaking, the greater the volume resistance is, the greater the surface resistance will be.

FR4 G10 glass fibre sheet epoxy plate fibreglass manufacturer ZTelec Group has produced a kind of good insulation sheet. It not only has the good insulation performance, but also has corrosion resistance and fire prevention. At present, as the development of technology is increasingly mature, more excellent performance was developed, we must pay attention to identify the quality when choosing. Only qualified FR4 G10 glass fibre sheet epoxy plate fibreglass can have good use effect.
