Complete manufacturing solutions with highly experienced engineers and diagnostic support to ensure customer products always conform to their test specification.

XJ TAG developer


Our knowledge in Design for Test (DFT) will provide product development and design engineers with added support in good practice techniques that will lead to robust and efficient production testing and diagnosis processes.

Our preference is to develop testing methods during early product development, however we can also work on existing product design to assist testing methodology, hardware and software using:

  • Custom Test Equipment Design and Development
  • Boundary scan, XJtag test and diagnostic
  • Functional Test rigs (manual or automatic)
  • Electrical safety testing of complete boxed products
  • Flash/device programming

While visual inspections can confirm to some extent that the product is assembled correctly, electrical and functional testing is required to ensure that a product is fully functional and meets a required specification. All bare boards are subject to an ICT (In-Circuit Test) during the PCB fabrication process. Once assembled boards can be tested using a variety of methods. These may include further ICT (Bed of nails), Flying probe, Functional Test with or without a Burn-in period.  Additional requirements especially during design and development phases may include EMC (Electromagnetic Compatibility Testing), where we can assist with further support.
