Process, quality and inspection
The numbers your design has to fit inside
The process windows we run, the quality system they sit under, and the inspection chain. Every figure comes from our own floor.

Solid bands are standard production. Outlined bands are quoted per project, with the stackup confirmed by an engineer before the purchase order.
| Parameter | In-house range | Notes |
|---|---|---|
| Layer count | 1–58 | 2–8 layers are the standard production band; 10–20 layers and HDI are quoted per project; 58 layers on request |
| Min line / space | 2.5 mil | 2.5 mil on the HDI band, 6 mil (0.15 mm) is the cost-optimum standard; mechanical drill 0.2 mm, laser micro-via 0.1 mm (4 mil) |
| Copper thickness | 0.5–20 oz | Heavy copper starts at 3 oz (105 µm); 20 oz equals 700 µm |
| Board size | 600 × 1200 mm | Maximum working area; finished thickness 0.4–3.2 mm; annular ring 0.15 mm minimum |
| Placement rate | 80,000 CPH | Single-line capability on an ASM SIPLACE X4iS; Yamaha YSM20R rated 72,000 CPH. Real output depends on board mix and component count |
| Placement accuracy | ±25 µm | 01005 and 0201 passives through to BGA at 0.25 mm pitch; fine pitch to 0.3 mm; component height to 25 mm on SMT |
| Impedance control | ±10% | ±5% on premium builds; measured on board-edge TDR coupons, differential pairs to 100 Ω |
| Surface finish | ENIG | Ni 3–6 µm + Au 0.05–0.1 µm to IPC-4552; ENEPIG, OSP (0.2–0.5 µm, 6-month shelf life), immersion silver and tin, HASL, hard gold 150–200 HK25 |
Quality system
Certified, audited, and inspected ten times over
ISO 9001:2015 certified and audited annually by SGS, with UL 796 recognition for board manufacturing. Between incoming material and the shipping carton every order passes ten inspection gates.
ISO 9001:2015
Certified by an accredited body and audited every year by SGS. The scope covers design, manufacturing, assembly and test, with an internal audit programme between the annual visits.
UL 796, recognised
Recognised for printed wiring board manufacturing, so your end product can carry the UL component recognition its own listing depends on.
RoHS & REACH, compliant
Lead-free production on all nine SMT lines. Per-board material declarations and test reports ship with the goods, backed by a 3TG conflict-minerals policy and CMRT on request.

Full scanned certificate package released on request. Automotive-grade work is quoted as process capability with PPAP and IMDS documentation, and medical-grade work with serialisation and full traceability to the lot. Every panel also passes AOI on all nine SMT lines (Omron VT-RNS or SAKI BF-18D), X-ray on a Nordson DAGE XD7600NT at a minimum of five pieces per lot, and electrical test on a Takaya APT-1500F flying probe or an Agilent i3070 ICT with 3,072 test points.
