What are the requirements for PCB multi-layer circuit board sampling?

　　Nowadays, various enterprises pay special attention to product quality. In the manufacturing industry, the improvement of product quality also plays an important role in the industry's reputation. PCB multi-layer circuit boards have good quality in the circuit board manufacturing industry. Therefore, many PCB multi-layer circuit board manufacturers will conduct multi-layer board sampling before production to verify whether the circuit design performance meets the requirements. The following is an analysis of the requirements for PCB multi-layer circuit board sampling?

　　1. Neat appearance. When making samples of PCB multi-layer circuit boards, it is necessary to ensure that the product has a smooth appearance without burrs, and that there are no bubbles or delamination between the sample wires and solder mask. Under such appearance cleanliness requirements, PCB multi-layer circuit boards can ensure better soldering effects and can be used for a long time without any connection obstruction problems. This appearance cleanliness also ensures that the PCB multi-layer circuit boards produced by merchants meet the actual appearance requirements for use.

　　2. Reasonable requirements for CB board sampling process. After the sample of the colorful structural board, it is also necessary to study whether its process is reasonable, such as whether there may be mutual interference between circuits, and whether the solder joint connection during soldering is well tinned, which is particularly important. In this design, electronic components made of PCB multi-layer circuit boards can ensure longer and smoother operation.

　　3. Requirements for CAM optimization. To obtain higher quality PCB multi-layer circuit boards, relevant CAM processing is carried out during sampling. This processing method adjusts the line width, spacing, and optimizes the solder pads to ensure better signal interaction between PCB multi-layer circuit boards, making the quality of power circuit board sampling superior.
