1. Single-sided PCB
The substrate material is mainly paper phenol copper laminate (paper phenol as the base, copper foil on top) and paper epoxy copper laminate. Most of them are used in home appliances such as radios, AV appliances, heaters, refrigerators, washing machines, and commercial machines such as printers, vending machines, circuit machines, and electronic components. The advantage is low price.
2. Double-sided PCB
The substrate material is mainly glass-epoxy copper laminate, glass composite copper laminate, and paper epoxy copper laminate. Most of them are used in personal computers, electronic musical instruments, multi-function telephones, automotive electronic equipment, electronic peripherals, electronic toys, etc. As for glass benzene resin copper laminate, glass polymer copper laminate is mostly used in communication equipment, satellite broadcasting equipment, and integrated mobile communication equipment due to its excellent high-frequency characteristics. Of course, the cost is also high.
3. 3-4 layer PCB
The substrate material is mainly glass-epoxy or benzene resin. The main uses are personal computers, ME (Medical Electronics, medical electronics) machines, measuring machines, semiconductor testers, NC (Numeric Control, numerical control) machines, electronic switches, communications machines, memory circuit boards, IC cards, etc. There are also glass synthetic copper laminates as multi-layer PCB materials, mainly focusing on its excellent processing characteristics.
4. 6-8 layer PCB
The substrate material is still mainly Glass-Epoxy or Glass benzene resin. It is used for electronic switches, semiconductor testers, medium-sized personal computers, EWS (Engineering Work Station, engineering workstation), NC and other machines.
5. PCB with more than 10 layers
The substrate is mainly made of Glass benzene resin material, or Glass-Epoxy is used as a multi-layer PCB substrate material. The application of this type of PCB is relatively special, most of which are large computers, high-speed computers, communications machines, etc., mainly because it has excellent high-frequency and high-temperature characteristics.
6. Other PCB substrate materials
Other PCB substrate materials include aluminum substrates, iron substrates, etc. The circuit is formed on the substrate, and most of them are used in rotary machines (small motors) and cars. There is also a flexible PCB (FlexiblPrintCircuitBoard), where the circuit is formed on materials such as polymers and polyesters, and can be used as single-layer, double-layer, or multi-layer boards. This flexible circuit board is mainly used in the movable parts of cameras, OA machines, etc., and the connection between the above-mentioned rigid PCBs or the effective connection combination between rigid PCBs and flexible PCBs. As for the connection combination method, due to its high elasticity, its shape is diverse.
