Specifications

FR-4 Material:
1.Color: natural , yellow, black
2.Size:1020*1020mm 1020*2000mm
3.Dielectric properties

FR4 Laminate Sheet is a glass fabric reinforcement in an epoxy resin binder. The natural color is light green. It is the most versatile laminate with extremely high mechanical strength, good dielectric loss properties, and good electric strength properties under both dry and humid conditions. It certifies to NEMA FR4 ;

 

Characteristics:

 (1) Good mechanical workability

 (2) Good flatness, smooth surface,no pits

 (3) Good heat resistance and moisture resistance

 (4) In high temperature electric performance is stable

 (5) Higher mechanical properties and dielectric properties

 (6) In the middle temperature with high mechanical properties

 

Application:

 (1) Used in mechanical, electrical and electronic high insulation structure parts

 (2) Used in high-performance electrical insulation requirements,such as the FPC Stiffener, PCB drilling pads,fiberglass meson,potentiometer,carbon film,printed glass fiber,precision planetary gear (chip grind),precision test plates,electrical (electrical) equipment insulation stays baffle plate insulation,transformer insulation boards,electrical insulation,grinding gears , electronic switches,insulation board and so on;
