The structure and characteristics of domestic commonly used circuit boards
The Internet era has broken the traditional marketing model, and a large number of resources have been gathered together to the greatest extent through the Internet, which has also accelerated the development speed of FPC flexible circuit boards, and then as the development speed accelerates, environmental problems will continue to appear in PCB factories. In front of him. However, with the development of the Internet, environmental protection and environmental informatization have also been developed by leaps and bounds. Environmental information data centers and green electronic procurement are gradually being applied to the actual production and operation fields.
There are also many types of circuit boards. According to different insulating materials, they can be divided into paper substrates, glass cloth substrates and synthetic fiberboards; according to different binder resins, they can be divided into phenolic, epoxy, polyester and polytetrafluoroethylene; according to use Can be divided into general type and special type.

1. Circuit board phenolic paper laminate is a laminate made of insulating impregnated paper (TFz-62) or cotton fiber impregnated paper (1TZ-63) impregnated with phenolic resin by hot pressing. Adhesive paper on both surfaces can be attached Use a single sheet of alkali-free glass dipping cloth, and cover one side with copper foil. Mainly used as a printed circuit board in radio equipment.
2. Circuit board phenolic glass cloth laminate is a laminate made of alkali-free glass cloth impregnated with epoxy phenolic resin by hot pressing. One or both sides are coated with copper foil, which has light weight, electrical and mechanical properties. Good, convenient processing and other advantages. The surface of the board is light yellow, if melamine is used as the curing agent, the surface of the board is light green and has good transparency. Mainly used as a printed circuit board in radio equipment with higher operating temperature and operating frequency.

3. Circuit board polytetrafluoroethylene laminate is a kind of copper-clad board made of polytetrafluoroethylene board as the substrate, coated with copper foil and hot pressed. Mainly used for printed boards in high frequency and ultra high frequency circuits.
4. Circuit board epoxy glass cloth laminate is a commonly used material for hole metallized printed boards.
5. The soft polyester copper-clad film is a ribbon-shaped material made of polyester film and copper by hot pressing. In the application, it is rolled into a spiral shape and placed inside the equipment. In order to reinforce or prevent moisture, it is often poured into a whole with epoxy resin. Mainly used as flexible printed circuit and printed cable, and can be used as a transition line for connectors. iPCB is happy to be your business partner.
