Manufacturing Process
How This Unit Is Made
Housing parts are moulded in our own mould workshop, so a tooling change on an ODM project does not depend on an outside supplier's queue. PCBA, assembly, ageing and packing all happen in the same building, which keeps the feedback loop between a test failure and a process fix down to hours.
