We track the progress of a motherboard from the start of the production line to the finish. See how it gets soldered, coppered, scanned, tested, etched and polished off.
"Before the motherboard can begin to take shape, the inner layer must be sheared and drilled. There are about 15,000 holes made in each inner layer motherboard. The process takes around 30 minutes to complete ten 'inner layer' PCBs at a time on each machine."
