Single Side Universal PCB Prototype Board Printed Circuit Protoboard DIY Solder. Single-sided spray tin green oil fiberglass circuit boards, also known as universal boards, experimental boards, which is a universal design of circuit boards, usually covered with standard Ic pitch (2.54mm) round independent pads on the board, it looks like the whole board are small holes, so it is also commonly referred to as the “hole board” compared to the professional PCB printed circuit boards, hole boards With low cost, easy to use, flexible expansion features. Uniform color, bright tin spray plate. Good quality, high temperature resistance. Not easy to oxidize, not easy to deformation. Is a flame-resistant material grade code, the meaning of the resin material by the. Through the combustion state must be able to self-extinguish a material specification, it is not a material name, but a material grade, so the general circuit boards used in the FR-4 grade material has a very wide range of types, but most of the so-called four-function (Tera-Function) of the epoxy resin plus filler (Filler) and glass fibers made of composite materials. FR-4 Epoxy Glass Cloth Laminate, according to the use of different purposes, the industry is generally known as: FR-4 Epoxy Glass Cloth, insulating board, epoxy board, epoxy resin board, brominated epoxy resin board, FR-4, fiberglass board, glass fiber board, FR-4 reinforcing board, FPC reinforcing board, Flexible PCB reinforcing board, FR-4 epoxy resin board, flame-retardant insulating board, FR-4 laminates, epoxy boards. 4 laminated board, epoxy board, FR-4 optical board, FR-4 glass fiber board, epoxy glass cloth board, epoxy glass cloth laminated board, circuit board drilling pad. Main technical characteristics and applications: stable electrical insulation properties, good flatness, smooth surface, no pits, thickness tolerance standards, suitable for high-performance electronic insulation requirements of products, such as FPC reinforcement board, PCB drilling pads, glass fiber dielectric, potentiometer carbon film printed fiberglass boards, precision vernier gears (wafer milling), precision test panels, electrical (electrical) equipment insulation spacer, insulation boards, insulation boards. Equipment insulating spacer, insulating pads, transformer insulating boards, motor insulating parts, grinding gears, electronic switch insulating boards and so on. According to your choice.
