Manufacturing Center
See the lines. Know the equipment. Verify the process.
Full SMT, through-hole, box-build and test capability under one roof in Changsha — the same lines that have shipped medical, automotive and industrial electronics since 2002. US orders are produced and shipped from this facility.
Process
Standard build flow
Every unit follows the same routed process with full traceability records.
SMT
- 01
Solder Paste Printing
Stencil printing with SPI (solder paste inspection) on 100% of boards before placement.
- 02
Component Placement
High-speed and flexible placers handle 01005 passives up to fine-pitch BGA and connectors.
- 03
Reflow Soldering
Multi-zone reflow with profiled thermal curves per board type, logged per batch.
- 04
AOI Inspection
Automated optical inspection on all SMT-side joints; X-ray for BGA and hidden joints.
DIP
- 01
Through-Hole Assembly
Wave or selective soldering for through-hole components and connectors.
Test
- 01
In-Circuit Test
ICT validates assembly integrity and component values before functional test.
- 02
Functional Test
Customer-specific functional test fixtures verify the assembled unit end-to-end.
Finishing
- 01
Conformal Coating
Optional conformal coating per IPC-CC-830 for harsh-environment and power products.
- 02
Box Build & Packing
Enclosure assembly, firmware loading, EOL test and retail-ready packaging.

Production & shipping base
Detailed line-count, headcount and daily-output figures are being finalized with our operations team. Ask your engineering contact for current capacity during quoting.
Process control
How the process stays honest
Controls that run on every build — not audit-day theater.
ESD control
Full ESD S20.20 program — grounded workstations, smocks, wrist straps and daily audits.
Moisture control
MSD handling and baking per J-STD-020 / J-STD-033 for moisture-sensitive components.
Traceability
Board-level serialization; per-unit process records retained for customer audits.
Inspection discipline
SPI, AOI and X-ray on SMT joints; 100% ICT or FCT before shipment.
First article control
FAI on every new build; sign-off required before volume release.
Change control
No unapproved process, component or source changes — ECN discipline with customer notification.
Factory tour video
A 2–3 minute walkthrough of the Changsha floor — receiving to packing — is in production. Ask for the preview link, or request it with your quote.
See it before you commit
Photos show equipment; video shows how a program actually moves through it. US customers can request a live video walkthrough of their own build area before first article approval.
