Manufacturing · Quality
Three quality gates on every order, a 100% final electrical test on every unit, and an in-house lab that hands you the data — not a subcontractor's word. This is the page for the buyer who came to audit us.
The short answer
Every order passes three quality gates — IQC on incoming parts, IPQC in process, and OQC before it ships — sampled to GB/T 2828.1 Level II. On top of that, every single unit gets a 100% final electrical test: safety and function on power, continuity and hipot on cable. It runs in our own lab, and the data ships with the order.
Quality is checked three times before a unit leaves — on the way in, on the line, and on the way out — so a problem is caught at the station where it happens, not at your dock.
Every component and material is checked against spec on arrival — magnetics, PCBs, enclosures, connectors, copper — with mill and material certificates, sampled before anything reaches the line.
First-piece confirmation and running checks at the station — solder, winding, assembly, and dimensional — so a drift is caught on the line, not discovered at the end of the run.
A final audit of finished goods before packing — appearance, function, packaging, and marking — sampled to GB/T 2828.1 Level II, on top of the 100% final electrical test every unit already passed.
The equipment that produces the data you audit against — calibrated and on our own floor, grouped by what it tests.
On our test bench
Power test bench
Chroma ATE
Programmable AC/DC test systems for electrical safety and functional test.
Hipot & HV insulation
Dielectric withstand and insulation-resistance on every power build.
Burn-in & aging racks
Sustained-load aging to surface early-life failures before they ship.
Fluke calibration

Output ripple and noise measured against the spec envelope.
Cable test bench
Continuity & hipot
Pin-to-pin continuity and dielectric test on 100% of assemblies.
Pull-force / tensile
Termination and strain-relief pull tested to the drawing.
Salt-spray
Corrosion testing on connector plating and shells.
Combustion / flammability
Jacket and housing flammability checks for the rated class.
A custom build is validated before it is produced at volume. It is how we keep a spec problem out of a full run.
A sample built on the production line and process — not a hand-made mock-up — so what we test is what you will actually receive.
The sample is tested against your requirements — voltage, connector, cable construction, and certification — and the results are shared before sign-off.
When the run starts, IPQC confirms the first piece against the approved article before the line is released to volume.
Production proceeds under the same drawing, test procedure, and gates — with the approved sample as the reference.
Quality your procurement team can audit isn’t a claim — it’s a file. Every order ships with the records below, each verifiable by file number, alongside the management-system standards our manufacturing runs under.

On top of that, the three gates (IQC on incoming, IPQC in process, OQC before ship) are sampled to GB/T 2828.1 Level II. The 100% test and the sampling plan are separate layers, not one or the other.
We sample to GB/T 2828.1 (equivalent to ISO 2859-1 / ANSI Z1.4) at General Inspection Level II, with the acceptance limits set per program and confirmed on your quote rather than quoted as a generic number. That sampling sits on top of the 100% final electrical test every unit already passes.
Yes. The UL file number, DoE Level VI efficiency data, FCC, and the electrical / continuity / hipot results ship with the order, along with the certificate of origin and HTS classification — each verifiable by file number at the source.
Yes. Before a run, a production-representative sample is tested to your spec and the first piece is confirmed by IPQC. Production does not start until that first article is signed off against your requirements.
Yes. We build in our own plants, so you or your auditor can review the process on the floor, the test capability, and the real data read against your spec — not a sales showroom or a subcontractor’s word.
On product: UL 62368-1, DoE Level VI, FCC, RoHS, and REACH. On manufacturing systems: ISO 9001, ISO 14001, ISO/IEC 27001, TL 9000, QC 080000, ESD S20.20, and Amfori BSCI — each verifiable by file number.
Send the spec and the certifications you need — we’ll quote it and tell you exactly what test data ships with the order. A person answers, usually within one business day.
Three gates, a 100% final test, and an in-house lab whose data ships with the order — behind a US company you can hold accountable. Then you elect where it is built: China or Vietnam, one drawing set, one UL file.
