Superior Abrasion Resistant FR4 Fiberglass Panel Applications

November 07, 2024

FR-4 board (FR-4 fiberglass board) is one kind of epoxy fiberglass cloth substrate, it is a kind of substrate with epoxy resin as binder and electronic grade fiberglass cloth as reinforcing material.FR-4 is a code name of flame-resistant material grade, which means that the resin material must be able to extinguish by itself after the combustion state, and the flame-retardant grade can be up to UL94V0 grade, and it passes the ROHS related environmental protection test. It has passed the ROHS test.

FR-4 is not a material name, but a material grade. HONY Plastic Fiberglass Cloth Board is mainly divided into five grades: G10 (A1,A2,A3), G11 (A1,A2), HB (A0,A2,A3), FR4 (A1,A2,A3), F5 (A1), the general technical specifications are: bending strength, peeling strength, thermal shock properties, flame retardant, volume coefficient of resistance, surface electrical conductivity, and so on. Energy, volume resistance coefficient, surface resistance, dielectric constant, dielectric loss angle tangent, glass transition temperature Tg, dimensional stability, maximum operating temperature, warpage, etc..

Glass fiber board is mostly for electronic Insulation Materials, for the wear-resistant parameters of the board is not high, different industries and applications for wear-resistant and other performance requirements, provide relevant data information, we will target the production of epoxy resin board formula for improvement, which is more mature process. Wear-resistant FR4, Tourmaline wheel use FR4 is used to do glass, lenses, silicon wafers, hard disk and other kinds of flat polishing process fixtures, also known as polishing fixtures, polishing pads and so on.

Polishing process development for many years, has been very mature, in recent years, cell phones, tablet computers and other mass electronic products popularized a lot, the rapid development of the touch screen, the development of polishing lenses by leaps and bounds, the raw material of the touring wheel by the initial blue steel sheet into the FR-4 fiberglass plate.

Tourbillon wheel manufacturing process is very delicate, lens or silicon, gemstone polishing is a very fine process, so the finished product for the tourbillon wheel requirements are also very fine, of course, even today, there are still a lot of glass factories use stamping to manufacture tourbillon wheels, the reason is simply because of this way of production costs are very low, and polished workpiece is also no requirement, so will choose to stamping.

At present, the majority of the tourbillon wheels are now processed by means of computerized gongs, and the great advantage of this method is that the finished product has a very high machining precision, which can be controlled within 0.02mm, and the cut surface is very smooth and clean, and there won't be any burrs, and even the traces of machining can't be seen.
