The factors that affect the quality of printed circuit board
Leave a message
With the rapid development of the electronic product industry, printed circuit boards, as the main component of electronic products, have also entered a period of rapid development. The competition in the industry has become increasingly fierce. In order to produce high-quality printed circuit board products, we need to do a good job in controlling from the following aspects.
1.Materials
There are many kinds of PCB materials, such as FR-4, metal core, ceramic core, etc. Different materials have different properties, such as dielectric constant, coefficient of thermal expansion, thermal conductivity, etc., which will directly affect the performance and quality of PCB. Raw materials are the foundation for ensuring the quality of printed circuit boards. If the material is not good, the produced printed circuit board is prone to cracking, layering, bubbles and other problems. Sihui Fuji adopts reputable material suppliers in the industry, starting from the source of printed circuit boards, to do a good job in producing high-quality printed circuit boards.
2.Design
The design of the printed circuit board is one of the key factors. Whether the design is reasonable and meets the functional requirements of the circuit will directly affect the performance and quality of the pcb.
3.Manufacturing process
The production process of printed circuit boards involves many high-tech production processes, mechanics, electroplating, chemical engineering and other related academic knowledge. The production process of boards is also relatively complex, and each process of the product must be produced according to strict process requirements. At the same time, professional inspection instruments are also required to check whether the product is qualified. The manufacturing process of pcb includes printing, chemical etching, drilling, plating and other steps. Whether the manufacturing process is scientific and reasonable, whether the operation is standard, and whether the tightness will directly affect the quality of printed circuit board.
4. Environment
The environmental conditions of printed circuit boards can also have an impact on their quality, such as temperature, humidity, static electricity, etc. During manufacturing, transportation, and use, improper environmental conditions can have an impact on the quality of printed circuit boards.
5.Detection method
The detection method of PCB quality will also have an impact on its quality. Whether the detection method is scientific and reasonable, whether the accuracy is high, and the environmental conditions during the detection will directly affect the detection results, thus affecting the quality of the PCB.
6. Production equipment
Printed circuit board equipment is the basic way to improve the quality of circuit boards by ensuring their hardware quality, increasing equipment investment, and achieving efficient and fast equipment. Sihui Fushi keeps up with the pace of technological development and continuously strengthens the updating and upgrading of equipment. At present, our company has a complete set of production equipment and machines.
7. Personnel Management
As the main force in PCB production, we need to pay special attention to personnel recruitment and management. The quality of personnel has a direct impact on the quality of printed circuit boards, and the stability of personnel also affects the continuous improvement of printed circuit board quality. Sihui Fuji employs 70% of local employees, which can provide sufficient human resources. In addition, because local employees are close to home, their stability is higher and there will be no problem of high turnover rates.
