Rapid prototyping
allows quick yet
thoughtful decision

Quick response is what distinguishes us on the EMS market. And that is what our customers are looking for specificly when evaluating their ideas in R&D phase. We guarantee not only
3-week delivery time for the high-complexity PCB, but – as a part of the well-reputable EMS company – we can support our customers with the wide range of additional services:

  • Material and PCB acquiring mainly basing on Fideltronik
    inventory and catalogue suppliers (components delivery time
    up to 5 working days, PCBs delivery time 3 -15 working days)
  • SMT reflow soldering (chip components from 0201,
    BGA pitch 0.35mm, Pin-In-Paste)
  • THT wave, selective or manual soldering
    (axial, radial, manual assembly, PressFit)
  • Testing (standard AIO, on demand: Flying probe,
    ICT, FCT, X-ray, visual inspection, manual test)
  • Conformal coating, siliconing, potting
  • Final (mechanical) assembly
  • Protypes build report
  • Packing and shipment
  • Rework process (to help our clients with product
    modification if needed).

Quality under control

Validation testing
is essencial to meet
regulatory requirement

It also helps to leverage performance of the final product and reduce the risk of costly non-compliance on the final design stage.

Validation test are planned and executed by qualified engineers in our own laboratory and include:

  • Electromagnetic compatibility (EMC) tests
  • Environments tests: Thermal, Humidity and Aging
  • Optical tests
  • Performance and endurance
  • Functional tests
  • Safety and control tests
  • Certification process lead, including DFMEA coordination
  • MTBF calculation replacement
  • DFT, DFM, DFR verification & support

We rely on our domain knowledge and expertise in delivering the best service quality to our clients, according to their needs and expectations.

Drawing from our extensive expertise, we can lead our clients through whole certification process for global markets, e.g., CE / UL / FCC.

We are here to support your engineers on each and every stage of the preparations.
