PCB manufacturing is an important link in the manufacture of electronic products, and the quality is directly related to the quality and reliability of the entire product. In the PCB manufacturing process, some problems are often encountered, and how to solve these problems is a skill that must be mastered in PCB manufacturing. FasTechCircuit will introduce common problems and solutions in PCB manufacturing.

1. Common problems in PCB manufacturing
（1）Poor quality of the line
Poor quality of lines is one of the most common problems in PCB manufacturing. The poor quality of the line is mainly manifested in the breakage, short circuit, adhesion and other phenomena of the line, which will cause the circuit to fail to work normally.
（2）Poor Quality of Pads
Poor quality of pads is another common problem in PCB manufacturing. The poor quality of the pad is mainly manifested in problems such as virtual soldering of the pad, poor plating, and too small pad, which will cause the components to fail to be bonded to the PCB.
（3）Poor quality of piercing
Perforation is an important step in the PCB manufacturing process. The poor quality of perforation is mainly manifested in problems such as inaccurate perforation position, too large or too small perforation aperture, and out-of-round perforation. These problems will cause components to fail to bond on the PCB.
（4）Poor Quality of Soldermask
Solder mask is an important step in PCB manufacturing. The poor quality of solder mask is mainly manifested in problems such as cracking of solder mask, uneven thickness of solder mask, incomplete pad coverage of solder mask, etc. These problems will affect PCB electrical resistance and corrosion resistance.
（5）Poor electrical performance
Poor electrical performance is an important problem in PCB manufacturing, mainly manifested in poor electrical connections, unstable electrical characteristics, etc. These problems will affect the stability and reliability of the circuit.

2. Second, the solution in PCB manufacturing
（1）high quality material
The quality of materials in PCB manufacturing directly affects the quality and reliability of PCBs. Therefore, high-quality materials should be used as much as possible in PCB manufacturing, such as high-quality electrolytic copper foil, high-temperature resistant materials, etc.
（2）Parameters that control the manufacturing process
Parameter control in the PCB manufacturing process is very important, such as controlling temperature, pressure, time and other parameters can effectively avoid some problems in the manufacturing process, such as circuit breakage, short circuit and other problems.
（3）Strict Quality Inspection
After the PCB is manufactured, strict quality inspection is required to avoid some problems, such as broken lines, short circuits, and virtual soldering of pads. Quality inspection should include visual inspection, electrical testing, X-ray inspection and other methods.
（4）Enhance worker training
Problems in PCB manufacturing are often caused by insufficient skills of operators. Therefore, the training of PCB manufacturing workers is very important, and the education of workers' skills training and quality awareness should be strengthened.
（5）Optimizing PCB Design
The quality of PCB design directly affects the quality and reliability of PCB manufacturing. Therefore, an optimized design scheme should be adopted in PCB design to avoid some manufacturing problems, such as circuit breakage, short circuit and other problems.

Common problems and solutions in PCB manufacturing need to be mastered and applied carefully. Only by strengthening the management and control of the PCB manufacturing process can the quality and reliability of PCB manufacturing be improved, thereby providing better protection for the manufacture of electronic products.
