How to detect and avoid defects in PTH PCB assembly-深圳市海博精密电路有限公司

Adequate inspection is required:The detection of the above-mentioned defects can be done manually or automatically. The inspection process is crucial for ensuring the quality of the PCB. Image processing technology is used to compare the assembled circuit board with a reference known good unit image. If there is not sufficient testing, the circuit board may enter subsequent processes and cause testing failures, or worse, the circuit board may detach from the entire assembly process and be shipped to the customer.

Focus on detection and occurrence control:The quality control of through-hole PCB assembly should focus on detection and occurrence control. Like occurrence control, through-hole PCB assembly services should have monitoring control to understand common defects. This is usually analyzed through a Pareto chart to gain a clear understanding of the main defects. Then a root cause analysis must be conducted to investigate potential through-hole PCB assembly machine issues, process gaps, material quality issues, and inconsistencies in the PCB production process.
