Case-Based Online Training for Improving Visual Inspection Capability of Employee in Electronic Manufacturing

Many different types of PCB defects can occur throughout the printed circuit board assembly process. The procedure of quality control is essential. A human inspection is important to ensure that the PCBA is delivered in excellent condition. It is critical to train QC employees to understand PCBA inspection standards to determine which PCBAs are acceptable. High rates of PCBA reject, even though the defects are acceptable to the customer, will have an impact on production costs. To improve Quality control performance, the development of decision-making skills of PCBA visual inspection employees was researched. Because to the COVID19 situation, case-based training was provided via online tools. However, in order to clear up any misunderstandings and conduct PCBA inspection tests, face-to-face discussion was still needed. In addition, the trained QC employee's performance was measured using attribute gauge repeatability and reproducibility, which indicated that the QC employee's decision-making capability had increased. When compared to appraisers before training and standard respectively, employee inspection performance was 11.94 % and 5.69 % better.
