Double-sided circuit board, pcb board manufacturers, PCB board introduction

1, composite PCB substrate

Composite substrate is also known as [powder board] the most common composite base copper clad board in the market today are single and double-sided CEM-1, CEM-3 half glass fiber board, 22F, etc., with wood pulp fiber paper or cotton pulp fiber paper as a reinforcing material, while supplemented by glass fiber cloth as a surface reinforcing material, two materials made of flame retardant epoxy resin.

2.Phenolic PCB paper substrate

Phenolic substrate is also known as [flame retardant board] the most common V0 board, cardboard, FR-1, FR-2, FE-3, 94HB, XPC, etc., because its main material is wood pulp fiber paper, after phenolic resin pressure and synthesis of a PCB board, its main characteristics are low cost, low price, low relative density, the disadvantage is not fire, the main application areas of children's consumer electronics.

3, glass fiber PCB substrate

Glass fiber board is also known as [epoxy board, fiber board] mainly by the epoxy resin as a binder, while using glass fiber cloth as a reinforcing material, this plate out of the PCB board fire resistance, height resistance, by the environment is small, the most commonly used to this substrate is a double-sided PCB, multi-layer PCB board, the conventional process: lead-free tin spray, green oil folded word, 1.6 thick plate, suitable for a variety of power supply board, control board, in communications The most commonly used substrate is double-sided PCB, multilayer PCB, conventional process: lead-free tin spraying, green oil folding word, 1.6 thick plate, suitable for various power supply board, control board, in the communication, instrumentation, automotive, computer industry is widely used.

4.LED aluminum substrate

led sheet is relatively special, it is a metal-based copper-clad panels with good heat dissipation, general single panel by the three-layer structure, respectively, the circuit layer (copper foil), insulation layer and metal base layer. For high-end use is also designed as a double-sided board, the structure of the circuit layer, insulation layer, aluminum base, insulation layer, circuit layer. Very few applications for multilayer board, can be made of ordinary multilayer board with insulation layer, aluminum base laminated.

5.Other substrates

In addition to the above often see the three at the same time there are metal substrates and laminate multilayer (BUM), it is worth noting that we will often see the board will be printed on top of the two letters KB, which is the abbreviation of Kingboard PCB board, in addition to Kingboard and Sang Yi SL, Taiyao TUC, Koki GDM, Changchun L, Changxing EC, Hitachi H, etc..

In addition to the above substrates there are laminated multilayer boards and metal substrates, many times we will see KB two letters on the finished PCB board, it is the abbreviation of Kingboard plate, in addition to Kingboard and Sang Yi SL, Taiyao TUC, Koki GDM, Changchun L, Changxing EC, Hitachi H, etc., like this plate from the source to protect the performance of the product, of course, the management of the production line and The experience of the staff is also very important.
