Electronic cloth alkali free glass fiber cloth professional copper-clad board

Electronic cloth alkali free glass fiber cloth professional copper-clad boardThere are a total of 33 specifications, the thin one is called 10 4 fabric with a thickness of only 0.028mm; the heavy one is called 7652 fabric, which can reach 252g/m2. These special specifications of electronic cloth are not widely used in the electronics industry. There are three commonly used specifications for electronic fabrics in the electronics industry. The one with a large usage is 7628 cloth, with a thickness of 0.173mm and a unit area mass of 204.4 g/m2; Next is 2116 cloth, with a nominal thickness of 0.094mm and a unit area mass of 102g/m2; The one with slightly less usage is 1080 cloth, with a nominal thickness of 0.053mm and a unit area mass of 46.8g/m2.

7628 electronic fiberglass cloth is mainly made of electronic grade fiberglass yarn (E-GLASSFIBER) woven in a plain weave. Its main performance and characteristics include good electrical insulation performance, fire resistance, flame retardancy, waterproofing, aging resistance, weather resistance, high strength, high modulus, etc. Widely used in epoxy copper-clad laminates, PTFE, high-temperature adhesive tape (PET), sports equipment, prepreg backing, silicone tape electrical insulation products, printed circuit boards, fireproof boards, insulation boards, as well as aviation, * fields, etc. Main varieties of fiberglass cloth: (i.e. thickness: 0.18mm, 0.1mm, 0.08mm, 0.05mm, 0.03mm, 0.14mm) Label: 7638 cloth, 7629 cloth, 7628 cloth, 2116 cloth, 1080 cloth, etc. Product features: 1. Excellent bundling, low static electricity, and low lint content. 2. Good temperature resistance and extremely low color difference. 3. Has good interfacial properties with the matrix resin. 4. It has very good fluidity in resin. 5. Can endow composite materials with good physical and chemical properties. 6. Use silane type coupling agent. 7. Using proprietary impregnating agents, the short cut fibers have good compatibility with the matrix resin.

The main properties and characteristics of 7628 glass fiber cloth include good electrical insulation performance of the substrate, fire and flame retardancy, aging resistance, and high strength. The fabric structure is tight, flat, and has clear patterns. It is widely used in the production of epoxy copper-clad laminates, electrical insulation products, printed circuit boards, fire-resistant insulation boards, and aviation fields.

Conventional width: 1000-1270MM Thickness: 0.2MM
