PCB Knowledge:
In the process of PCB board, it is inevitable that external factors will cause electrical defects such as short circuit, open circuit and leakage of electricity. In addition, with the continuous evolution of PCB towards high density, fine spacing and multilayer, if the bad board can not be screened out in time,leaving it to flow into the assembly process will cause more cost waste. Therefore, improved testing technology is also a solution for PCB manufacturers to reduce scrap rate and improve product yield.
In the production process of electronic products, the cost loss caused by sputum has different degrees at each stage, and the earlier the discovery, the lower the cost of remedy.
In the manufacturing process of PCB, there are three phases that must be tested:
1. Inner layer etched
2. After etching the outer circuits
3. Final product
Each stage usually has 100% test of 2~3 times, and the bad board is screened for further treatment. Therefore, the test station is also the best source of data collection for analyzing process problems. Through statistical results, the percentage of open circuit, short circuit and other insulation problems can be obtained. After heavy work, the test is performed again. After the data is sorted, the quality control method can be used to find out the root of the problem and then solve them.（bare pcb）
