pcb is what boards such as epoxy boards and what boards ah

PCB circuit board as the mother of electronic products, but also software to achieve the necessary carrier, different devices have different PCB material, for the rigid printed circuit board (Rigid Printed Circuit Board, referred to as RPCB ) is divided into a variety of, in accordance with the PCB board enhancement materials are generally divided into the following categories.

1, phenolic PCB paper substrate

Because of this PCB by pulp wood pulp and other components, so sometimes also become cardboard, V0 board, flame retardant board and 94HB, etc., it is the main material is wood pulp fiber paper, pressurized by phenolic resins and synthesized by a PCB. the characteristics of this paper substrate is not fire-resistant, can be punched ﹑ low-cost ﹑ low-cost, relatively Density is small. Phenolic paper substrate we often see XPC, FR-1, FR-2, FE-3, etc., and 94V0 belongs to the flame retardant cardboard, is fireproof.

2, composite PCB substrate

This also becomes the powder board, wood pulp fiber paper or cotton pulp fiber paper as a reinforcing material, supplemented by fiberglass cloth as a surface reinforcing material, the two materials made with flame retardant epoxy resin. There are single-sided half-glass fiber 22F, CEM-1 and double-sided half-glass fiber plate CEM-3, etc., of which CEM-1 and CEM-3 of these two is currently the most common composite-based copper-clad laminate.

3, glass fiber PCB substrate

Sometimes also become epoxy boards, glass fiber boards, FR4, fiber boards, etc., which is an epoxy resin as a binder, and at the same time with glass fiber cloth as a reinforcing material. This kind of circuit board working temperature is higher, subject to the environmental impact is very small, in the double-sided PCB often use this kind of board, but the price relative to the composite PCB substrate price is expensive, commonly used thickness of 1.6MM. this kind of substrate is suitable for all kinds of power supply boards, high-level circuit boards, in the computer and peripheral equipment, communication equipment, etc. widely used.

4, other substrates

In addition to the above often see the three at the same time there is a metal substrate as well as multilayer multilayer board (BUM).

It is important to note that we often see circuit boards printed on the top of the two letters KB, which is the Kingboard PCB board abbreviation, in addition to the Kingboard there are SangYi SL, Taiwan Yiu TUC, Koki GDM and so on.
