Home / Quality
Every board tested. Not every tenth board.
100% electrical test, AOI at inner and outer layers, coupon-based lab verification. Quality here is a sequence of checks, not a certificate on a wall — though we have that too.
Inspection flow
Six gates between your files and your dock
Each gate can stop a lot. When it does, you hear about it the same day — with photos and a proposed disposition, not a vague delay notice.
Incoming material
Laminate and copper thickness verified against the spec; lot recorded against your work order.
Inner-layer AOI
Film AOI plus post-etch AOI before lamination. Opens, shorts and spacing violations caught here, not after press.
Drilling & plating
Hole verification, copper thickness by X-ray and microsection on coupons from the same panel.
Impedance & finish
Coupon measurement against your target, coating thickness, solderability after final finish.
100% E-test
Netlist comparison on every board. Flying probe for prototypes, fixture test for volume.
Final & pack
Visual inspection, dimensional check, vacuum packing with desiccant, shipment photos on request.
Standards
What we build to — and what we won't claim
Default workmanship is IPC-A-600 Class 2. Class 3 is available on request and quoted accordingly. We don't print certification logos we haven't been audited for, and we don't describe boards as compliant with regulations that apply to the finished assembly rather than the bare board.
- IPC-A-600 Class 2 / Class 3Class 3 requires a documented build review before tooling — ask when you request the quote.
- ISO 9001 quality managementCertified and audited; certificate available on request.
- RoHS-compliant materialsLead-free finishes and compliant laminates as standard; material declarations can be issued per build.
- REACH declarations on requestIssued for the specific materials used in your order — not a blanket claim.
Measurement
What the lab can prove
If a parameter matters to your design, ask for it on the report. Coupons are kept with the work order.
| Check | Method |
|---|---|
| Hole wall copper thickness | Microsection, measured at multiple points per coupon |
| Surface finish thickness | X-ray fluorescence, gold/nickel/tin/silver |
| Impedance | Coupon-based TDR measurement against your target, with a signed report |
| Solderability | Wetting test on finished panels |
| Line width / spacing | Optical measurement at defined panel locations |
| Electrical continuity | 100% netlist test; four-wire low-resistance probe for fine features |
| Material composition | RoHS analyser screening; declarations from laminate suppliers on file |
Quality questions
Tell us which parameter keeps you up at night.
Impedance tolerance, barrel cracks after thermal cycling, mask registration on fine-pitch parts — name it in your RFQ and the quote will state how we control it and how we prove it.
