Quality Assurance
Quality, gated and documented
Five quality gates from receiving dock to final inspection, IPC-A-610 Class 2/3 workmanship, and a document pack that survives customer audits. First-pass yield ≥99%, on-time delivery ≥98%.
System & metrics
The numbers we run on
An ISO 9001:2015-certified quality management system and an ISO 14001:2015 environmental system; RoHS/REACH declarations available with your shipments.
Process standards
Standards we build to
Acceptance criteria are written into the traveler, so what your inspector checks matches what our line was told to build.
Standards start at goods-in
The standards we build to — and how they land in your build
IPC-A-610 Class 2 is the default acceptance class on every quote; Class 3 is scheduled on request. The table below maps each standard to what actually happens on the floor.
| Standard | Governs | How it lands in your build |
|---|---|---|
| IPC-A-610 Class 2 (rev. J) | Workmanship acceptance | Default acceptance class for every assembly build |
| IPC-A-610 Class 3 (rev. J) | High-reliability acceptance | On request; e.g. through-hole barrel fill ≥75% (§7.5.3) |
| J-STD-001 | Soldering requirements | Hand-soldering and rework operator criteria |
| IPC-CC-830 | Conformal coating materials | Acrylic / silicone / polyurethane qualification on the coating line |
| ANSI/ESD S20.20 | ESD control program | Grounding, wrist straps and ESD flooring across the shop |
| J-STD-033 | MSD handling | Dry cabinets <5% RH, MSL 1–6 exposure tracking and bake-back |
| J-STD-020 | MSL classification | Label-level moisture sensitivity rating honored at intake |
| IPC-A-600 | Bare board acceptance | Incoming inspection criteria on customer and sourced PCBs |
| IPC-6012 | Bare board performance | Qualification and performance checks at receiving |
| ISO 9001:2015 | Quality management system | Certified QMS: document control, nonconformance and corrective action |
| ISO 14001:2015 | Environmental management | Certified environmental system across the facility |
| RoHS / REACH | Substance compliance | Compliance declarations available per shipment |
Quality gates
Five gates between your files and the courier
Each gate has a defined check, a record and a hold point — defects stop where they start instead of surfacing at final test.
Gate 5, final inspection
Boards are checked against the light before packing
Workmanship, test results and the document pack are verified at the last gate; the Certificate of Conformance is issued per shipment.
- Gate 1 · Incoming: bare boards and consigned parts vs IPC-A-600 and your data sheet.
- Gate 2 · SPI 100%: paste volume, height and alignment caught before placement.
- Gate 3 · Post-placement: first-article plus in-line polarity, value and offset checks.
- Gate 4 · AOI + X-ray: 100% AOI after reflow; 100% X-ray on every BGA and QFN.
- Gate 5 · Final: workmanship, test records and document pack verified before packing.
Hidden joints, imaged
100% X-ray on BGA and QFN — not sampled
Ball-grid-array and QFN joints hide under the package, so sampling is a guess. Every hidden joint on every board is X-rayed, and the images attach to the traceability file that ships with your CoC — ask to see them with your next build.

ESD · MSD · Traceability
Two parallel programs: static and moisture
Component damage is mostly invisible at final test — so it is prevented at the bench and the cabinet, not inspected in afterwards.
ESD to ANSI/ESD S20.20
Grounded benches, wrist straps and ESD flooring run across SMT, DIP, coating and packing — one program, audited, not a sign at the door.
MSD to J-STD-033
Moisture-sensitive devices live in dry cabinets below 5% RH; MSL 1–6 floor-life clocks are tracked with humidity indicator cards and bake-back records.
Batch-level traceability
Component lots and date codes are linked to the build record, and a Certificate of Conformance travels with every shipment.
Audit document packs
PPAP Level 1–3 packs for automotive-aligned programs and DHR-style documentation for medical programs, provided under your audit workflow.
Certificates & compliance
Papers you can call in
Issued and audited: ISO 9001:2015 and ISO 14001:2015 (certificate scans below). IATF 16949 and ISO 13485 are supported as aligned workflows with PPAP Level 1–3 / DHR-style documentation under customer-led audits — scope letters available on request. Originals shown in person or by video audit any time.
ISO 9001:2015
Quality management system — audited and renewed on cycle.
CE
Conformity support for finished assemblies entering the EU market.
RoHS / REACH
Restriction-of-hazardous-substances compliance for every build.
