SMT production process will implement strict process management, but in our actual production process, defective products that do not meet the process requirements will appear. These defective products are separated through quality inspection for analysis and repair. So what testing methods do PCBA processing plants have?

PCBA processing

Visual inspection: The human eye directly observes and inspects the quality of SMT products. The inspection effect is related to the PCB mounting density.

AOI detection: automatic optical detection, an alternative to visual inspection. The detection speed is fast and accurate. The bad results of the detection are incorrectly marked on the display graphic.

ICT detection: circuit testing, circuit fault diagnosis is performed on the PCB after it is mounted. Welding defects such as open soldering, virtual soldering, and short circuits can be detected, and the fault diagnosis ability is very strong.

Quality inspection in SMT production can detect defects early to avoid defective products from flowing to the next process, reduce production costs, and achieve good process control.
