Via @tspascoal cheguei a este artigo "Shenzhen is Like Living in a City-Sized TechShop" e fiquei fascinado com a concretização do que é o poder de um cluster:
"That begins to describe the electronics farmer’s market
...
It’s naive to think of labor costs as China’s chief advantage in hardware manufacturing. The main advantage of being at the center of the supply chain is the iteration speed it permits. Need to find a particular part to fit a particular housing? Just blew a board and need a replacement part? Looking for a variation of a certain component? Then literally walk across the street and go get it. Even if you’re in the heart of the Silicon Valley sitting inside a TechShop that’s not possible. Looking for a segmented LED display? How about browsing through a case full of 75 different ones on the spot. Not sure about using the part in production? Talk to the factory rep and maybe jump in a car to see the factory line.
Aside from selection and immediacy, it’s easier for local designers to build their prototypes using the exact same tools as the production line uses, thus side-stepping possible manufacturing problems down the road and avoiding costly redesigns that plague most hardware projects. It’s also much easier to identify and design around components that are more popular by looking at what’s on sale at local markets than by searching online.
Huaqiangbei is the electronics component mecca, but it’s just one small part of the Shenzhen ecosystem. “I’d never hand-soldier a board. I just send an Eagle file off and get the completed board back later that day for a few bucks.” The town is full of service firms that have the equipment, expertise and capacity to handle quick turnaround on basic needs."
