That was quite a tour! I saw firsthand how a motherboard goes from raw material to a packaged product, with several eye opening steps in between. I never knew how many steps were involved in producing the actual PCB itself, and it was quite evident in the length of that part of the tour. The assembly part was also quite intriguing, with a single motherboard going from start to finish in a matter of minutes. I can see how ECS makes a claim of producing around 2 million boards a month with the number of assembly lines and people working each of them. The testing of each and every was what really impressed me. I was under the impression that only some of the boards would be randomly tested with the vast majority of them going straight into boxes. With ECS, not only is every board tested to ensure it works, but the company also goes ahead and stress tests random boards to verify strict quality control methods are being followed.
