Epoxy glass cloth laminate is impregnated with non-alkali glass fiber cloth by imported electricals to import epoxy resin, and the corresponding imported flame retardant, adhesive and other additives are added. Rigid sheet insulation material made of hot pressing.
1. Good mechanical processing performance can be machined into various components through lathe processing, stamping, cutting, drilling, sand blasting, milling, sawing and milling, etc. It is simple and practical in assembling method, and can be assembled by bonding, metal screw and riveting.
2. Good insulation strength, chemical resistance, radiation resistance and thermal shock resistance; Good tensile strength, flexural strength and low temperature adaptability; No matter in high humidity or dry environment, it has the characteristics of good electrical and electrical performance loss, and it has flame retardancy and heat resistance.
3. The water absorption rate is almost 0; After 24 hours of immersion, the water absorption rate was only 0.09 %.
4. Heat resistance level is above 160 ℃; Flame retardancy: UL 94 V-0.
FR - 4 is a kind of code of fire resistant material grade, represented by the mean resin material after combustion state must be able to put out a material specification, it is not a material name, but a level of material, so the general FR - 4 grade materials used in the circuit board has a lot of kinds, but most are based on the so-called four functions (Tera - Function) of epoxy resin and Filler (Filler) and glass fiber made of composite materials.
