FR4 Epoxy board EPGC202 Details

FR-4 epoxy fiberglass cloth substrate,Also known as EPGC202 is a kind of substrate with epoxy resin as binder and electronic grade glass fiber cloth as reinforcing material. Its bonding sheet and inner core thin copper clad plate are important substrates for making multilayer printed circuit boards.

Color: water green, yellow Regular size: 1020 × 2040mm, 1220 × 2040mm, 1220 × 1020mm, special size can be customized

 

Performance:

1. High mechanical properties, dimensional stability and impact resistance are higher than paper substrates
2. Good dielectric properties
3. Good heat resistance and moisture resistance, high working temperature, low performance due to environmental impact, moisture resistance
4. Good machinability, it has great advantages over other resin fiberglass cloth substrates. Color: water green, yellow, other colors can be customized

 

Use:

Insulation structural parts in motors and electrical equipment, including various types of switches FPC reinforced electrical insulating carbon film printed circuit boards, computer drilling pad mold fixtures (PCB test racks) and in humid environmental conditions and transformer oil Used in.
