Although I have talked a lot about the performance characteristics and uses of FR4 epoxy board, it is not very comprehensive. Today we mainly give a detailed explanation of the characteristics of the FR4 epoxy board.
Insulation: Its vertical layer electrical strength (in transformer oil of 90±2 °C, thickness 1mm): ≥14.2MVm, it is the best choice for many insulation components.
Convenient curing: Different curing agents are used, and the epoxy resin system can be cured in the temperature range of 0~180 °C.
High temperature resistance: its high temperature resistance is up to 140 degrees. In this way, there is no need to worry about the insulation properties being seriously damaged as the temperature increases.
Excellent flame retardant performance: it is an improvement of 3240 epoxy board. Its flame retardant performance meets the UL 94V-0 standard. The processing procedure is simple: only high temperature and high pressure are required in the entire processing. Convenient and fast.
Good appearance: its surface is very flat, no pits, thickness tolerance standards. Wide range of thicknesses: Its processing thickness ranges from 0.1mm to 100mm, let people have more choices.
Today’s FR4 epoxy board is now favored by people for its environmental protection, high quality and low price, and fast delivery. It enjoys a high reputation all over the world.
