In the electronics industry, circuit boards are a crucial component that enables connectivity and signaling between electronic components. As technology continues to advance, the performance and quality standards of circuit boards continue to improve. However, the problem of defective rate has been one of the major challenges faced by the circuit board industry.
The defective rate is the percentage of the number of nonconforming products produced during the manufacturing process. For the production of circuit boards, the defective rate is an important indicator of the quality of production. So, what should the defective rate of circuit boards be set at?
First of all, the standard of defective rate should be decided according to the application environment of the circuit board. For example, for some high-precision instruments, medical equipment, or military equipment, the quality of the circuit board is very high, and the defect rate is usually set at a very low level, or even zero defect. While some consumer products or daily necessities, its for circuit board quality standards are relatively low, a certain degree of defect tolerance is acceptable.
Second, the board's production process also has an impact on its defect rate. For manual welding, hand-assembled circuit boards, due to the influence of human factors, its defective rate is relatively high. For automated production lines on the production of circuit boards, due to a high degree of automation and a relatively stable production environment, its defective rate can be significantly reduced.
Finally, the company's own management and technical level will also affect the defective rate of the circuit board. Through scientific management and continuous technological innovation, enterprises can improve production efficiency and quality, reduce the defective rate of circuit boards.
Combining the above factors, the defective rate of circuit boards should normally be controlled at a level below 1%. Of course, for some high-end circuit board applications, the defective rate should be at an even lower level to ensure its stability and reliability. For circuit board manufacturers, constantly improve the technical level, strict quality management is to maintain the circuit board defective rate of low important means.
