What are the materials for printed circuit board processing?The raw materials of the printed circuit board industry mainly include alass fiber varn, copper foil copper clad laminate, epoxy resin,  wood pulp etc., and the copper cad laminate is made of copper foil, epoxy resin, glass fiber yarn and other raw materials.Common materials for rigid circuit boards include phenolic paper laminates, epoxy paper laminates, polyester glass felt laminates, and epoxy glass cloth laminates; common materials for flexible circuit boards indude nolvester polvimide Amine film. fluorinated ethvlene pronvlene film. loday the editor oflinazhi Circuit.

Ucreate PCB will talk to you about the substrate materials required for processing different types of printed circuit boards?

1. Single-sided PCB
Substrate materials are mainly paper phenol copper sheetlaminates (paper phenol as the base and copper foil on top), and paperepoxy resin(Epoxy) copper sheet laminates. Most ofthem 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 that they are low in price.

2. Double-sided PCB
Substrate materials are mainly Glass-Epoxy copper sheetlaminates, GlassComposite (glass composite) copper sheet laminates, and paper Epoxy copper sheetlaminates. Most ofthem are used in personal computers, electronic musical instruments, multi-function telephones, electronic equipment forautomobiles,electronicperipherals, electronic toys, etc. As for Glass benzene resin copper tensionedlaminates Glass polymer copper tensionedlaminates are mostly used in communication equipment, satellite broadcasting equipmentand mobile communication equipment due to their excellent high-frequency characteristics. Of course
the cost is also high.

3. Multilayer PCB
The substrate material is mainly Glass-Epoxyorbenzeneresin.The main uses are personal computers, Me (Medical Electronics medical electronics)machinesmeasuringmachines,semiconductortesting machines, NC(Numeric Control, numerical control machines, electronic switches, communication machines, memory circuit boards, IC cards, etc., and glass composite copper sheets Thelaminatedboard is used asamulti-ayer PCB material mainly focusing on its excellent processing characteristics.

4. High-level PCB
The substrate is mainly made ofGlass benzene resin material,or Glass-Epoxy is used as the multilayer PCB substrate material. The application of this type of PCB is relatively special, most of which arelarge-scale computers, high-speed computers. communication equipment,etc., mainly because it has excellent high-frequency characteristics and high-temperature characteristics.

5. Other PCB substrate materials
Other PCB substrate materials includealuminum substrates copper substrates, etc. Circuits are formed on substrates, and most of them are used in rotary machines (small motors) for automobiles. n addition there is also a flexible PCB(Flexible Print Circuit Board). The circuitis formed on materials such as polymers and polyesters.It can be used as a single-layer, double-layer, or multi-layer board.This kind offlexible circuit board is mainly used in the movable parts of cameras, OA machines, etc., and the connection between the above-mentioned rigid PCBs orthe effective connection combination between the rigid PCB and the flexible PCB. As for the connection combination method, due to its high elasticity, its shape is diversification.
