Industrial control box assembly processing
| PCB board | Ensure that the quality and design of the PCB board meet the requirements of the industrial control box. |
|---|---|
| Electronic components | Prepare the required electronic components according to the BOM (Bill of Materials), including DIP plug-ins, SMT patch components, etc. |
| Housing and accessories | Prepare the housing, heat sink, fixing screws and other accessories of the industrial control box. |
Customer requirement
A box-build assembly for an industrial controller: PCBA plus enclosure, wiring and harness, pilot build. Integration and ruggedness lead.
Manufacturing challenge
- PCB-to-harness mating must be verified for every unit.
- Enclosure sealing/routing affects EMC and field reliability.
- FCT is a system test of the assembled box, not just the board.
Solution
Kilandu runs this board through a controlled NPI-to-production flow rather than a one-shot build:
- DFM: footprint, stack-up and test-point review is completed and fed back before any parts are ordered.
- Sourcing: turnkey procurement of the BOM, with qualified alternates managed for long-lead and obsolete parts.
- SMT: high-speed SMT lines with inline SPI, AOI and X-ray on BGA, voiding and hidden joints.
- Assembly: selective DIP for through-hole content and, where required, conformal coating.
- Test: ICT for net integrity, then FCT for the board-specific functions above.
System-level FCT on the assembled box; IPC-A-610 Class 3 workmanship.
Result
First-article inspection to IPC-A-610 Class 2/3 is completed, a golden sample is retained as the release baseline, and a pilot run is signed off before mass production. Per-batch traceability (lot, AOI/X-ray records and ICT/FCT logs) is kept. Order quantities and the customer's specific acceptance result are confirmed per project.
