AOI和移动探针电测也常被认为可相互替代。实际上它们具有极不相同的技术和各自的优点。当作为互补而不是竞争时,AOI和探针电测(ET)可以共同解决整个PCB制造过程中的问题。所生成的有价值的归档数据,用于今后的生产和过程控制,成为错误检验的一个强有力的工具。 它们的技术除了不同之外也有相似之处。它们都适用于那些产品经常改变,小批量 AOI and mobile probe electrical measurements are often considered as alternatives. In fact they have very different technologies and their respective advantages. When complementary and not competitive, AOI and Probe Electrometry (ET) work together to solve problems throughout the PCB manufacturing process. The resulting valuable archive data for future production and process control becomes a powerful tool for error checking. Their techniques are similar except for their differences. They are suitable for those products often change, small quantities
