Quality system and certification
The site operates certified quality and environmental management systems, and boards are built and inspected to IPC-A-610 Class 2 or Class 3 depending on the application. The certificates themselves, the inspection stages, sampling and record retention are documented in full on the Quality Assurance page.
Process control in production
Every build carries a traveller through SMT, DIP, assembly, test and final inspection. Solder paste is checked at start of shift, reflow profiles are recorded per product, and first-article approval is required before a run is released. Deviations are raised against the customer drawing, not resolved silently on the line.
See Factory management for how production is planned and controlled.
Material and supply chain
Components are procured from authorised and franchised channels for critical parts, with cross-reference and lifecycle checks before substitution. Long-lead and allocation-risk items are flagged at quotation stage so they do not become a surprise mid-build.
See Supply chain and component sourcing.
OEM customers and experience
We build for more than 3,000 OEM customers across Europe, Russia and the Americas. Work is concentrated in industrial electronics and automation, instrumentation, energy storage and power electronics, medical devices, automotive electronics and IoT products. Board types range from battery-management and motor-drive control boards to power distribution units, HMI and display boards, communication gateways, sensor front ends and heavy-copper power boards. Typical volumes range from prototype batches to series production, with lead times of two to five weeks depending on material.
Real PCBA Case Studies
The builds below are anonymised PCBA case studies from our own production lines. Customer names, logos and order details are never published. What is published is the engineering: what the board had to do, what made it difficult, how it was manufactured, how it was tested, and the capability that demonstrates. Build-specific data such as layer count, board dimensions, BOM quantity and production volume is available under NDA on request.
All five builds run inside the same certified management system: IATF 16949:2016 (IATF No. 0596984) for automotive work, ISO 13485:2016 (cert. 35825MDQMS0021R0S) for medical work, and ISO 9001:2015 (cert. CN27125Q0392R0S) with ISO 14001:2015 (cert. CN27125E0142R0S) across the rest of the range. Workmanship is to IPC-A-610 Class 2 or Class 3 as agreed per project, and UL File No. E352816 is referenced only for assemblies covered by that file. Every certificate number, issuing body and validity date is published on the Quality Assurance page and can be verified with the issuing body.
- Automotive Electronics PCBA for a Tier-2 Supplier - body-control and sensor-interface module built under IATF 16949 (certificate 0596984) with lot and serial traceability, AOI and X-ray inspection, ICT and FCT.
- Medical Device PCBA for a Confidential OEM - control board for medical monitoring and diagnostic equipment built under ISO 13485 (certificate 35825MDQMS0021R0S) with full material and process traceability.
- BMS PCBA for an Energy Storage Application - battery management control board with cell voltage and temperature sensing, cell balancing and CAN communication, verified by functional test before shipment.
- Industrial Motor Control and Inverter PCBA - motor-control board for factory automation, where both ICT for component-level integrity and FCT for system-level control functions were required on the same board.
- EV Charger Control PCBA for a European OEM - control and power-management board for AC/DC charging stations, with customer-approved functional test and conformal coating on designated areas.
