PCB dry film which pcb bare board manufacturing

What does PCB dry film have?

Yongmingsheng metal core PCB manufacturer is introduced as follows:

1. Single-layer PCB

The base materials are mainly paper phenol copper laminate (paper phenol as the base and copper foil as the base) and paper Epoxy resin copper laminate. Most of them are used in domestic electricity products such as radios, AV appliances, heaters, refrigerators and washing machines, as well as commercial machines such as printers, vending machines, circuit machines and electronic components, with the advantage of low price.

2. Double-layer PCB

The base materials are glass-epoxy-copper tensor laminate, Glass composite and paper epoxy-copper tensor laminate. Most of them are used in personal computers, electronic musical Instruments, multi-function telephones, automobile electronic machines, electronic peripherals, electronic toys and so on. As for Glass benzene resin copper tensioning board, glass polymer copper tensioning board is mostly used in communication machines, satellite broadcasting machines and centralized mobile communication machines due to its high frequency characteristics. Of course, the cost is also high.

3. 3-4 layers PCB

The base material is mainly glass-epoxide or benzene resin. It is mainly used for personal computers, Me (MedicalElectronics) machines, measuring machines, semiconductor testing machines, numeric control machines, electronic switches, communication machines, memory circuit boards, IC cards, etc. It is also used for glass composite copper tensitive laminates as multilayer PCB materials, mainly focusing on its excellent processing characteristics.

4. 6-8 layers PCB

The base material is still glass-epoxide or Glass benzene resin. Used in electronic switch, semiconductor test machine, medium personal computer, EWS (Engineering Work Station), NC and other machines.

5. PCB with more than 10 layers

Use Glass benzene resin as the base material, or glass-epoxide as the base material for multiple layers of PCB. The application of this kind of PCB is relatively special, most of which are large computers, high-speed computers, communication machines, etc., mainly because of its high frequency characteristics and high temperature characteristics.

6. Other PCB substrate materials

Other PCB substrate materials still aluminum substrate, iron substrate, and so on. The circuit is formed on the substrate and is mostly used in rotary (small motor) cars. In addition, there is flexible PCB, circuit in polymer, polyester and other based material, can be as a single layer, double layer, to multilayer board. This kind of flexible circuit board is mainly used in the movable part of camera, OA machine, and the connection between the rigid PCB or the effective connection combination between the rigid PCB and the flexible PCB. As for the connection combination mode, due to high elasticity, its shape is diversified.
