In electronics world, printed circuit boards (PCBs) is very important. They like the brains of many devices we use daily, from smartphones to computers. Making these PCBs can be tricky sometimes. Thats where AOI testing come in. AOI stand for Automated Optical Inspection. This technology help check PCBs for mistakes. So companies like UC can find problems quick and fix them, because products work better and last longer. Let’s see how AOI testing make PCB manufacturing smarter and cheaper, and what new things happen in this tech.
