product description

Description of G10 

Colorful G10 fiberglass laminated board is also called epoxy resin alkali-free fiberglass laminated board. It is made by electronic grade fiberglass cloth impregnated with heat-resistant epoxy resin under hot pressing with stable electrical insulation property, good flatness, smooth surface and standard thickness tolerance. Colorful G10 fiberglass laminated board produced by ZTelec Group has various colors and types and its insulation class is F class.
Colorful G10
Application of G10

It is suitable for products with high requirements on electronic insulation performance,for example, FPC reinforced board, high temperature resistant board for wave soldering,precision star wheel, PCB test stand, deflection coil terminal board, electronic switch insulation board, copper clad plate substrate, etc. It can also be used to make insulation partitions and pads for electrical equipment, insulation parts for transformer and motor, etc.
