"Box build" is where your PCBA becomes a product โ not just a board. ๐ฆ
Too many hardware teams nail the circuit board, then stall at the final mile: enclosure fit, cabling, firmware flashing, testing, and retail packaging. That's exactly what box build assembly solves.
What a full turnkey box build actually includes (5 tiers):
1๏ธโฃ PCBA manufacturing โ SMT/THT + 3D AOI + X-ray for BGAs
2๏ธโฃ Enclosure & cabling โ molding, stamping, CNC, custom wire harnesses
3๏ธโฃ Electromechanical integration โ torque control, thermal pads, display/battery mount
4๏ธโฃ Firmware & system FCT โ automated flashing, RF calibration, burn-in
5๏ธโฃ Packaging & logistics โ retail kitting, ESD pack, FOB/DDP customs
Why Shenzhen?
๐ World's densest electronics supply chain โ distributors, molders, cable shops, packaging printers all within hours. One partner = one accountable quality chain. Scale from 50-unit pilot to 50,000-unit mass production on the same floor.
โ ๏ธ The quote trap to avoid:
A cheap "assembly labor only" quote often excludes tooling NRE, custom harnesses, real FCT jigs, and DDP freight. Always compare line-by-line โ visual power-on โ tested product.
Never ship on visual inspection alone. Demand 3 levels of test:
โ
ICT (bed-of-nails: shorts/opens/values)
โ
FCT (every port, wireless, display powered)
โ
Burn-in (thermal chamber, kill early failures)
๐ Protecting IP in China:
โข Sign a bilingual NNN agreement (Non-Disclosure, Non-Use, Non-Circumvention) under Chinese law โ not a Western NDA
โข Own 100% of your molds, dies & test fixtures
โข Flash proprietary firmware in an isolated, encrypted environment
At MakerPCB we run all five tiers under one roof โ eliminating the tolerance gaps between your enclosure and internals.
