The mainstream PCB material classification mainly includes the following types: FR-4 (glass fiber cloth base), CEM-1/3 (composite substrate of glass fiber and paper), FR-1 (paper-based copper-clad laminate), metal-based clad Copper plates (mainly aluminum-based, a few iron-based) are the most common material types at present, and are generally referred to as rigid PCBs.
The first three are generally suitable for products that require high-performance electronic insulation, such as FPC reinforcement boards, PCB drilling backing boards, glass fiber mesons, carbon film printing glass fiber boards for potentiometers, precision planetary gears (wafer grinding), precision testing Plates, electrical (electrical) equipment insulation stay partitions, insulation backing plates, transformer insulation plates, motor insulation parts, grinding gears, electronic switch insulation plates, etc.
The metal-based copper clad laminate is the basic material of the electronics industry. It is mainly used for processing and manufacturing printed circuit boards (PCBs), and is widely used in electronic products such as televisions, radios, computers, computers, and mobile communications.
