摘要:

高产量电子生产中的制造测试流程通常在产品开发期间固定,并在每个单元上不变执行,即使故障模式和工艺条件发生变化。这保护了质量,但也带来了不必要的测试成本,而现有数据驱动方法大多优化静态测试子集,既不能在线适应变化的缺陷分布,也未明确控制漏检风险。本文提出一种自适应测试选择框架,结合贪心集合覆盖的离线最小成本诊断子集构建与 Thompson-sampling 多臂老虎机的在线学习,通过滚动过程稳定性信号切换全测试和缩减测试计划。在两个印刷电路板组装阶段——功能电路测试和终检测试——共覆盖 28,000 块板运行。离线分析识别出零漏检的缩减计划,在功能电路测试中将测试时间减少 18.78%,在终检测试中减少 91.57%。在时间验证中,静态缩减产生了 110 个漏检缺陷和 8 个终检缺陷,而自适应策略通过在实践中出现不稳定时恢复全覆盖,将漏检降至零。这些结果表明,在线学习可以在减少测试负担的同时保持制造质量,为跨生产领域的自适应测试规划提供实际途径,并为公司提供经济和物流改进。

英文摘要:

Manufacturing test flows in high-volume electronics production are typically fixed during product development and executed unchanged on every unit, even as failure patterns and process conditions evolve. This protects quality, but it also imposes unnecessary test cost, while existing data-driven methods mostly optimize static test subsets and neither adapt online to changing defect distributions nor explicitly control escape risk. In this study, we present an adaptive test-selection framework that combines offline minimum-cost diagnostic subset construction using greedy set cover with an online Thompson-sampling multi-armed bandit that switches between full and reduced test plans using a rolling process-stability signal. We evaluate the framework on two printed circuit board assembly stages-Functional Circuit Test and End-of-Line test-covering 28,000 board runs. Offline analysis identified zero-escape reduced plans that cut test time by 18.78% in Functional Circuit Test and 91.57\% in End-of-Line testing. Under temporal validation with real concept drift, static reduction produced 110 escaped defects in Functional Circuit Test and 8 in End-of-Line, whereas the adaptive policy reduced escapes to zero by reverting to fuller coverage when instability emerged in practice. These results show that online learning can preserve manufacturing quality while reducing test burden, offering a practical route to adaptive test planning across production domains, and offering both economic and logistics improvement for companies.
