How to determine the quality of the circuit board, there are the following methods:
1. Standard rules for size and thickness
The thickness of the circuit board is different from that of the standard circuit board.
Customers can measure and check according to thickness and specification.
2. The light color
The outer circuit board is covered with ink, and the circuit board can be used as an insulating layer.
If the color of the board is not bright and less ink is used, the insulation board is not good.
3. Welding appearance
Because there are many parts on the circuit board, if the welding is poor and the parts are easy to fall off, the welding quality of the circuit board will be seriously affected.
Having a good look, careful identification, and a strong interface is important.
High quality PCB boards need to meet the following requirements
1. Line width, line width and line spacing should meet the requirements to avoid line heating, open circuit and short circuit.
2. Copper skin is not easy to fall off at high temperature.
3. Copper surface is not easy to oxidize.
4. No additional electromagnetic radiation.
5. The shape should have no deformation, the hole position of the circuit board and the deformation error between the circuit and the design should be within the allowable range.
6. High temperature, high humidity and special environmental tolerance should be considered.
