The difference between a double-sided PCB circuit board and a single-sided circuit board is that only one side of the single-sided circuit board is printed with lines, while both sides of the double-sided circuit board are printed with lines. Generally speaking, the production process of double-sided PCB circuit boards is divided into wire method, plugging method, masking method and graphic plating-etching method.
Advantages of PCB circuit boards coated with anti-paint
1. Reduce the occurrence of failures
Coating anti-paint on the PCB circuit board can effectively prevent the occurrence of related faults such as insulating the tin feet between the circuit board surfaces, anti-static, short circuit and so on. 2. Prevent oxidation
Coating anti-paint on the PCB circuit board can protect the tin points on the surface of the circuit board from being oxidized by air to make it more beautiful, and it can also prevent dust from hindering and affecting the normal operation of the circuit board.
3. Extend the service life
Coating anti-paint on the surface of the PCB circuit board can form a protective ability on the surface of the circuit board, which can effectively prevent moisture, insulation, anti-static and other characteristics, ensure that the circuit board can work normally in harsh conditions, and delay the failure of the circuit board. service life.
4. Improve appearance
Both transparent and colored anti-paints can improve the appearance of printed circuit boards, while the latter can also ensure a higher degree of confidentiality by covering components and design layouts. High-end fpc circuit board
