1. According to the different uses, the industry is generally called: fr4EpoxyGlassCloth, insulating tube, epoxy tube, epoxy resin tube, brominated epoxy resin tube, fr4, glass fiber tube, glass fiber tube, fr4 reinforcement tube, FPC Reinforcing pipe, flexible circuit board reinforcing pipe, fr4 epoxy resin pipe, flame retardant insulating pipe, FR-4 laminated pipe, epoxy pipe, fr4 light pipe, fr4 glass fiber pipe, epoxy glass cloth pipe, epoxy Glass cloth laminated tube, circuit board drilling pad tube. Main technical features and applications: stable electrical insulation performance, good flatness, smooth surface, no pits, standard thickness tolerance, suitable for products with high performance electronic insulation requirements.
A material standard specified by NEMA American Electrical Manufacturers Association, the corresponding IEC International Electrotechnical Commission standard is EPGC202, and there is no domestic standard corresponding to it.
Surface colors are:
White fiberglass tube, basket color fiberglass tube, etc.
fr4 is the base tube used by PCB, which is a type of sheet material. According to different reinforcing materials, the sheets are mainly classified into the following four types: fr4: glass cloth base pipe, FR-1, FR-2, etc.: paper base pipe, CEM series: composite base pipe, special material base pipe (ceramic, metal base pipe) etc.) fr4 is a tubular laminate made of special electronic cloth impregnated with epoxy phenolic resin and other materials and hot pressed at high temperature and high pressure.
Features: It has high mechanical properties and dielectric properties, good heat resistance and moisture resistance and good machinability.
Uses: used as insulating structural parts in motors and electrical equipment, including various types of switches, FPC, reinforced electrical insulation, carbon film printed circuit boards, computer drilling pads, mold fixtures, etc. (PCB test stand) and can be used in humid environments. condition and use in transformer oil.
The main material is imported prepreg, the color is white, yellow, green, still has high mechanical strength at room temperature 150 ℃, good electrical performance in dry and wet state, flame retardant, used for electrical, electronic and other industries insulation structure parts ,It is carefully manufactured with imported raw materials, domestic presses and standard processes; the main specifications are 1000*2000mm1020mm*1220mm, because of the advantages of raw materials, it ensures high quality and low price, timely delivery, and has a stable customer base at home and abroad, And enjoy a high reputation.
It is a kind of substrate with epoxy resin as adhesive and electronic-grade glass fiber cloth as reinforcing material. Its bonding sheet and inner core thin copper clad laminate are important base materials for making multi-layer printed circuit boards.
Mechanical properties, dimensional stability, impact resistance, and moisture resistance are higher than those of paper-based tubes. It has excellent electrical performance, high operating temperature, and its performance is less affected by the environment. In terms of processing technology, it has great advantages over other resin glass fiber cloth-based pipes. This type of product is mainly used for double-sided PCB
