对印刷电路组装 (PCA) 工厂的目视检查流程进行了人体工程学改进研究。通过主观评估和直接观察来研究该过程。发现了三个问题：操作人员眼睛问题、检查时间不足、目视检查效果不佳。这些问题每年造成高达 298,240 美元的拒收成本、质量差、客户不满意以及职业健康和安全差。为了纠正这些问题，采取了人体工程学干预措施：减少放大镜的使用、使用不那么刺眼的检查模板、仅检查未进行电气测试的组件以及引入目视检查序列。这些干预措施节省了拒收成本，减轻了操作员的眼睛疲劳、头痛和流泪的情况，降低了客户现场的缺陷率，并提高了工厂的生产力和客户满意度。
An ergonomics improvement study was conducted on the visual inspection process of a printed circuit assembly (PCA) factory. The process was studied through subjective assessment and direct observation. Three problems were identified: operators’ eye problems, insufficient time for inspection and ineffective visual inspection. These problems caused a huge yearly rejection cost of US $298,240, poor quality, customer dissatisfaction and poor occupational health and safety. Ergonomics interventions were made to rectify the problems: reduced usage of a magnifying glass, the use of less glaring inspection templates, inspection of only electrically non-tested components and introduction of a visual inspection sequence. The interventions produced savings in rejection cost, reduced operators’ eye strain, headaches and watery eyes, lowered the defect percentage at customers’ sites and increased the factory’s productivity and customer satisfaction.
