Precautions for PCB production process

　　Accuracy of design documents

　　The success or failure of PCB production is related to the accuracy of the design documents, so it is necessary to design PCB boards as accurately as possible and conduct multiple verifications and modifications.

　　Accuracy and quality of plate making

　　Plate making is the core process of PCB production, and its accuracy and quality directly affect the quality and stability of the PCB board. Therefore, the plate making process requires precise operation and control to ensure the accuracy and quality of the plate making.

　　Etching control

　　Etching is one of the key processes in PCB production, and it is necessary to control the parameters such as etching time, temperature, and concentration to avoid incomplete or excessive etching.

　　Quality of welding

　　Welding is one of the important processes in PCB production, and it is necessary to control the temperature, time, pressure and other parameters of welding to ensure the quality of welding and avoid problems such as weak welding or short circuit of solder pads.
