Box Build Assembly in China
System-level integration: enclosure, wiring, sub-assemblies, firmware loading, functional test and packaging.
What this service covers
Box build extends well past the circuit board. Enclosure supply, harness assembly, firmware loading and final functional test each introduce a new subcontractor. We record the boundary of what the factory performs itself, since “full system integration” is one of the easiest claims to overstate.
Why there is no factory list on this page yet
ChinaPCB publishes a service page only after verifying at least eight factories for that service with a service-specific record. Current verified count: 0. Until that bar is met, this page stays out of the index rather than showing a list of name-and-address entries.
What a verified record will contain
- The legal entity and the production site where this service is actually performed.
- Which steps are in-house and which are subcontracted.
- The evidence level and the date the claim was last checked.
