What are the preparations before the circuit board proofing?
There are simple and complex circuit boards. Simple circuit boards needless to say that proofing is easy, but if it is a complex circuit board proofing, you must be cautious. If you don’t need to check the relevant testing tools during the circuit board proofing process, in case something goes wrong, It’s too late to find out when the circuit board is ready. Therefore, we must make sufficient preparations before proofing. The following summarizes some preparatory work before proofing for everyone to learn.

1. Making the physical frame

The closed physical frame is a basic platform for the future component layout and circuit board proofing. You must pay attention to accuracy. Moreover, it is best to use arcs at the corners, which can not only avoid scratches by sharp corners, but also make stress. Lighten up.

2. Introduce components and networks, and lay out components

When drawing the components and the network into the frame of the circuit board proofing, you must carefully follow the prompts, including the package form of the component and the problem of the component network. Because of the contrast prompts, problems are not prone to occur. Layout components and wiring have a great impact on product life, stability, and electromagnetic compatibility during circuit board proofing, so special attention should be paid. Generally speaking, there should be the following principles: placing order and paying attention to heat dissipation.

3. Wiring and adjustment

It is best to pay attention to the requirements of processing parameters when wiring, or to a reliable circuit board proofing manufacturer, the defective rate will be greatly reduced. After completing the wiring, all you need to do is to adjust the text, individual components, wiring, and apply copper (this work should not be too early, otherwise it will affect the speed and bring trouble to the wiring), also for the convenience of production, Commissioning and maintenance.

4. Check the network

Sometimes the network relationship of the circuit board drawn is different from the schematic diagram due to misoperation or negligence. At this time, it is necessary to check and verify. So after finishing painting, you should check it first, and then carry out follow-up work.
The above content introduces to you the work that should be prepared before the proofing of the circuit board from the aspects of physical frame production, introduction and layout of components and networks, layout components, wiring and adjustment, and check and verification of the network. In addition, when choosing a proofing company, the most The best choice is a circuit board proofing company with a good reputation, so as to improve the accuracy of the circuit board.
