Description:

FR4 Based 2 Layers PCB is a kind of PCB board which is very important in circuit board. It is suitable for a wide range of high-tech industries such as: telecommunications, power supply, computer, industrial control, digital products, science and education equipment, medical equipment, automobiles, aerospace defense, etc.


FR4 Based 2 Layers PCB are usually made of epoxy glass cloth coated copper foil. It is mainly used for communication electronics with high performance requirements.

Equipment, advanced instrumentation, and electronic computers.

The production process of double-panel is generally divided into process wire method, plugging method, masking method and pattern plating-etching method, etc. The process flow of pattern plating and etching method is shown in the figure.


The difference between a double-sided PCB board and a single-sided PCB board is that the single-panel circuit is only on one side of the PCB board, and the double-sided PCB line can be in the two sides of the PCB board, and the double-sided PCB board is used in the middle. The lines are connected.

The parameters of the double-sided PCB board double-sided PCB board production and single-sided PCB board are not the same as the production process, but also a copper-plating process, that is, the process of turning the double-sided line.
