Quality Control

ISO 9001, ISO 14001, IATF 16949 and UL recognised production, with AOI inspection and electrical testing on every order.

Our Commitment

Boards that behave in your assembly line

A board that passes our inspection but fails at your reflow oven costs far more than the board itself. Our process is built around that fact: consistent copper, consistent finish, consistent hole quality — batch after batch.

  • ISO 9001 quality management system
  • ISO 14001 environmental management
  • IATF 16949 automotive quality management
  • UL recognised and RoHS compliant boards
  • SGS tested — reports available on request
  • IPC-A-600 Class 2 / 3 acceptance criteria
  • Full AOI inspection and electrical testing

Choosing the right finish for your assembly

Finish affects solderability, shelf life and cost. We will advise which one suits your process.

Reliability

For products that must not fail

Automotive, medical and industrial customers work with us because a returned board costs them far more than the board price.

🚗

Automotive

ECUs, lighting, charging and sensing modules, produced under IATF 16949 discipline to hold up under thermal cycling and vibration.

🏥

Medical

Monitoring, diagnostic and portable medical devices, where traceability and repeatability matter more than unit price.

🏭

Industrial

Control boards, drives and machine-tool electronics expected to run for years in the field without service.
