The audio circuit pc board mainly has the following four requirements

　　1. Neat appearance: When the audio circuit pc board is proofing, it needs to have a flat appearance, no burrs in the corners, and no blistering and delamination between the wires and the solder mask. Only in this way, the audio circuit pc board can ensure better welding effect, and also ensure that the audio circuit pc board produced by the manufacturer meets the appearance requirements of actual use.

　　2. Reasonable process requirements. The audio circuit pc board also needs to study whether its process is reasonable before proofing, such as whether there is mutual interference between the lines, etc., to ensure that the audio circuit pc board can run smoothly for a long time.

　　3. CAM optimization: In order to obtain high-quality audio circuit pc boards, relevant CAM processing is required when proofing.

　　4. Confirmation of proofing information: The user should have a clear understanding and regulation of the process requirements for audio circuit pc board proofing, so as to correctly convey it to the service provider.

　　The above are the basic requirements for audio circuit pc board proofing. High-quality proofing can make the audio circuit pc board have higher quality, and mass production can be carried out after ensuring the quality is correct.
