HOME / QUALITY & TESTING
Every unit passes the same seven gates.
Power supply quality control at VoltFab is a fixed sequence, not a slogan: IQC, SPI, AOI, X-Ray, hi-pot, functional test and 100% burn-in — each gate writing to the unit's serial record under an ISO 9001 quality system.
QC GATES
Seven gates, one serial record.
Sampling rate, pass criteria and the equipment behind every verdict — the table our auditors ask for first.
| Gate | Sampling | Pass criteria | Equipment |
|---|---|---|---|
| IQC incoming | AQL sampling per lot | CoC match, date-code and MSL verification | Incoming lab · FAI830 first article |
| SPI paste check | 100% of deposits | Volume, area and height within stencil spec | 3D SPI on GKG print lines |
| AOI post-reflow | 100% of panels | IPC-A-610 Class III component and joint criteria | MENTO MT2000 optical lines |
| X-Ray | Sampled lots + 100% battery welds | BGA voiding within IPC-7095 limits | X-Ray inspection station |
| Hi-pot | 100% of finished units | IEC 62368-1 dielectric withstand, no breakdown or arcing | AC hi-pot & ground-bond benches |
| Functional test | 100% of finished units | Rails in regulation under load, PMBus / SNMP polling OK | Programmed test fixtures |
| 100% burn-in | 100% of finished units | Zero-failure exit at full load in the aging room | Burn-in aging room |
END-OF-LINE TEST
The fixture unlocks burn-in — nothing else does.
At the end-of-line benches every finished unit runs its programmed sequence: output rails under load, protection trip points, telemetry polling over PMBus or SNMP, and metering checks against the ±1% billing-grade claim on PDUs. A pass verdict opens the burn-in slot; a fail locks the serial into the rework loop with the failure log attached. The sequence is enforced by the fixture, so no unit can reach the aging room untested.
TEST & INSPECTION EQUIPMENT
The instruments behind the gates.
MENTO MT2000 AOI
Optical gate on all seven SMT lines with Class III component, polarity and solder-joint libraries; defect images archived per lot.
FAI830 first article
Dimensional and BOM verification of the first panel at every changeover — the lot waits until the first article is signed off.
Hi-pot & ground bond
100% dielectric withstand testing to IEC 62368-1 limits; leakage current and ground-bond resistance are logged against each serial.
Burn-in aging room
Full-load, elevated-temperature aging with zero-defect exit criteria — the last gate, and the reason our DOA rate stays nameplate-low.
CERTIFICATION
Compliance by type, evidence on request.
We publish certification types, not scanned certificates — original system certificates and test documentation are shared with qualified buyers under NDA.
ISO 9001 quality system
The floor operates under an ISO 9001-certified quality management system covering SMT, assembly, test and burn-in. The system certificate is available to qualified buyers under NDA.
CE marking
Shipped programs carry CE compliance for the applicable EMC and safety directives, with the technical file maintained per product family and updated at each hardware revision.
RoHS / REACH
Materials compliance is controlled from IQC outward: RoHS and REACH declarations are collected per component lot and bundled into the shipment dossier for your market's review.
UL 62368-1 path
PDU and PSU platforms are engineered on a UL 62368-1 certification path — creepage, clearance and fire-envelope rules are design inputs, and type-test evidence is assembled as compliance-ready packages supporting your listing submittal.
UL 857 · IEC 61439-6 path
The busway line follows a UL 857 and IEC 61439-6 type-test path: 100% factory pretest on tap-off boxes, routine dielectric tests per run, and documentation prepared for third-party witnessing.
UN38.3 document chain
Lithium lines ship on a UN38.3 document chain — cell-level test summaries, MSDS and packing instructions PI965 / PI966 — so BBU programs clear export and air-freight review without stalling the schedule.
