The factory behind the charger
Two minutes from the Shenzhen metro, our facility turns bare PCBs and sheet metal into certified chargers — with quality gates at every step and serial traceability back to the component.
Four stages, one controlled line
From incoming materials to a packed container, every charger moves through the same four stages.
PCB assembly
Surface-mount and through-hole lines build control, power and communication boards in-house.
Module & enclosure
Boards, relays, contactors and cooling are integrated into the enclosure and wired to spec.
Test & calibration
Hi-pot, functional, OCPP and full-load tests with results logged per serial number.
Pack & ship
Export-grade packaging, palletization and documentation for sea and air freight.
Four gates, zero silent defects
Each stage ends with a documented gate — a unit cannot advance without a pass.
| Gate | Stage | What we verify |
|---|---|---|
| IQC | Incoming | Component batch sampling, PCB and enclosure conformance before line start. |
| IPQC | In-process | Solder quality, wiring and torque at defined stations during assembly. |
| FQC | Final | Full functional, safety and communication tests on 100% of finished units. |
| OQC | Outgoing | Pre-shipment audit, packaging and documentation against the PO. |
Built to scale with your orders
Our Shenzhen lines are sized for both pilot runs and container-load programs.
| Line | Capacity |
|---|---|
| AC wallboxes | 6,000 units / month |
| DC fast chargers | 800 units / month |
| SMT PCB assembly | 240,000 placements / hour |
| Rapid prototype | Pilot unit in 3 days |
Machines that do the heavy lifting
The line is tooled for precision electronics and heavy power hardware alike.
SMT placement
High-speed pick-and-place lines for fine-pitch control boards.
Reflow & wave soldering
Consistent joints for surface-mount and through-hole components.
AOI inspection
Automated optical inspection flags solder defects before they propagate.
Load banks
Programmable loads exercise chargers at full rated power before shipping.
Every charger has a paper trail
If a field issue ever appears, we trace it to the batch, the board and the component.
Serial-level tracking
Each unit carries a unique serial tied to its full test record.
Batch genealogy
Boards link back to component lots and supplier certificates.
Audit-ready records
Test logs and certificates are archived for warranty and regulatory audits.
