What are the differences between FR5 sheet and FR4 sheet?
Price FR-5 CCL is much more expensive than FR-4, but the material is really much better. We use FR-5 CCL to produce circuit boards, and UL certification (E301969).
FR-5 has better advantages than FR-4: 1, TG, TD higher; 2, better heat resistance, about twice the normal FR-4; 3, Z-CTE smaller, suitable for high Laminates; 4, T288 better.

FR4FR5 epoxy board by a special electronic cloth impregnated with epoxy phenolic resin and other materials by high temperature and high pressure hot plate made of laminated products. With high mechanical properties and dielectric properties, good insulation properties and heat resistance and moisture resistance, and a good mechanical processing. Application: for electrical and electrical equipment for the insulation structure of parts, also widely used In the PCB test; and can be used in humid environmental conditions and transformer oil. Specifications:. Plate: Thickness x Width x Length = 0.3 ~ 50mmx1020mm x 1220mm
