PCB厂商使用自动光学检测仪的目的是为了检测到重要的缺陷,而对于一些特殊设计和装饰性设计则不需要检测。如果要达到这一效果,就必须适当调整系统的检测参数。提供一种衡量AOI侦测性能的新颖方法。此种方法可以尽可能的减少漏测或误报产生的几率,通过考量漏测与误报的各自的成本,客户可据此结果来决定特定的机器的配备。关于自动检测设备选型机制示意图和方法,相关的实用工具及生产领域的简易实施方法也作了说明。
PCB manufacturers use automatic optical detector is designed to detect important defects, but for some special design and decorative design does not require testing. If you want to achieve this effect, you must adjust the system’s detection parameters. Provides a novel method of measuring AOI detection performance. This approach minimizes the chances of missed or false positives and allows the customer to determine the specific machine configuration by considering the respective costs of missed and false positives. Schematic diagram and method of automatic testing equipment selection mechanism, related to practical tools and production areas of simple implementation methods are also described.
