Amid the wave of PCB investment in Thailand, not every company is starting from the same place. Some companies build their factories and install equipment first, then work to demonstrate to customers that they can deliver. Others, by contrast, are driven overseas by customer demand.

However, it takes more than a steady order backlog to guarantee success in such a tremendous endeavor.

But from our perspective, the more interesting part of Delton’s story addresses a fundamental challenge facing Chinese PCB manufacturers expanding overseas: How do you transfer advanced manufacturing capabilities outside China’s mature supply chain and engineering ecosystem?
