High PCB quality

Through intensive contact with various circuit board manufacturers qualified by TQ and the application of defined design rules, your circuit board is produced in a high-quality and cost-effective manner.

Design for Manufacturing (DFM), high assembly quality

With the help and feedback of TQ’s own assembly production department, we keep our PCB design rules up to date and place your components on your PCB in compliance with all electrical requirements.


Design for Testability (DFT), best possible testability of the printed board assembly

Test procedures are coordinated at an early stage with the TQ specialist department for test equipment development. This is how we achieve optimal test depth at low cost. The layout is designed for the most effective and cost-effective optical and electrical testing possible.

In the area of E²MS we use qualified and validated standard processes which are combined, adapted and validated product-specifically.


IQ – Installation Qualification

With the Installation Qualification (IQ) we prove that a machine has been delivered and correctly installed in accordance with the requirements set out in the Design Qualification. This also includes checking that the appropriate working environment has been selected.

  • Definition of requirements for the equipment
  • Selection / procurement of suitable equipment
  • Careful inspection of the installation: operability, software inspection, safety equipment inspection, general functional tests, careful inspection of the equipment properties for the planned area of use.

OQ – Operation Qualification

Operation Qualification (OQ) checks the correct functioning of the equipment under real conditions. It is proven that the equipment delivers the expected results using product-specific settings.

  • Complete system check
  • Functional tests
  • Test and modification of all variable settings
  • Calibration
  • Software
  • Determination of the product-related process parameters


PQ – Performance Qualification

As part of the performance or performance qualification (PQ), we regularly monitor and evaluate process stability in relation to the respective quality criteria and the associated individual product characteristics.

It is proven that the process consistently achieves the defined quality characteristics under real production conditions and delivers reproducible and reliable results in regular use.

  • Quality control chart
  • Quality metrics
  • FPY evaluations

On the basis of this data, we control a continuous improvement process (PDCA cycle) and ensure consistently high product quality.
