Proofing requirements for PCB multilayer circuit boards

Nowadays, in the development of various enterprises, special attention is paid to the quality of the products. In the manufacturing industry, the improvement of product quality also plays an important role in the reputation of the industry. PCB multilayer circuit boards have good quality in the circuit board manufacturing industry. Therefore, many PCB multi-layer circuit board manufacturers will carry out multi-layer board proofing before production to verify whether the performance of the circuit design meets the requirements.

1. Clean appearance: The appearance of the PCB multi-layer circuit board needs to be proofed during the proofing. There is no burr at the corners, and there will be no blistering and delamination between the wire and the solder mask. In such an appearance, cleanliness is required. The PCB multi-layer circuit board can guarantee better welding effect, and can be used for a long time during use. There is no problem of blocked connection, and the neatness of this appearance also ensures that the PCB multi-layer circuit board produced by the merchant is in line with the actual use. The appearance requirements.

2. Requirements for CAM optimization: If you want to obtain a higher quality PCB multilayer circuit board, perform related CAM processing during proofing. This processing method adjusts the line width and optimizes the spacing between the pads. This is the only way to It can ensure that the circuit interaction between the PCB multilayer circuit boards has a better signal, and the quality of the power circuit board proofing is more superior.

3. Reasonable requirements for PCB board technology: after proofing, the colorful structure board also needs to study whether its technology is reasonable, such as whether there may be mutual interference between lines, and whether the problem of solder joint connection during welding is tinned Good is also particularly important. In this design, the electronic components made of the PCB multilayer circuit board will ensure a longer and stable operation.

The above are the basic requirements for PCB multi-layer circuit board proofing. High-quality proofing can make the PCB multi-layer circuit board have a higher quality. After ensuring the quality, mass production can be carried out. Therefore, the PCB multi-layer circuit board should be improved and reasonable The design plan is also for the better production of PCB multilayer circuit boards. Through this optimization method, the business will make the PCB multilayer circuit board show more prominent and more stable performance, and bring more help to the PCB multilayer circuit board production industry in China.
