A significant share of the world's consumer electronics pass through Shenzhen's supply chain. Huaqiangbei in Futian district is the nerve centre: SEG Plaza alone has 3,000+ component shops across 10 floors. Bao'an district runs PCB assembly. Longhua hosts Foxconn's largest global campus. Nanshan concentrates R&D for Huawei, ZTE, DJI, and Tencent.

You can source individual IC chips, resistors, and connectors from Huaqiangbei, or commission full PCBA runs from Bao'an factories with MOQs as low as 1 piece for prototypes. PCB prototypes cost $2 and arrive next day. 1688 search terms: 深圳电子元器件, 深圳PCB打样, 深圳PCBA加工. Sub-marketplace: ec.1688.com for electronics.
