Tests / inspections

Our principle for your product is a zero-defect strategy, so we strictly work according to the “Poka Yoke” procedure. Therefore, different test methods and testing devices are available optimising the production process of your components and ensuring safety and reliability of your product. That is our priority. We previously map out the testing strategies offering you different test methods and a compliance with our standards and quality requirements.

AOI

After the SMD assembly has finished, the automatic inspection device inspects the PCB for false polarities, missing components and defective soldering joints by means of an optical procedure. First of all, the inspection device takes several pictures of the PCB. Then a software programme specifically developed by us evaluates these pictures and identifies faults. Afterwards, faults can be analysed and remedied by our qualified personnel on professional rework stations. Furthermore, the default analyses are evaluated in order to draw conclusions from the defect occurrence and to steadily optimise and enhance the process of SMD assemblies.

ICT test

The circuit of a component is electronically checked by an In-Circuit-Test adapter. Finest needles contact defined points on the PCB and test the components for their functionality. The advantage of this procedure is that both the entire circuit and individual components are tested and checked. Defects in the PCB track, short circuits, open connections/ joints, soldering defects and misaligned components are thus detected and removed on a component level.

Our ICT system can carry out analogue as well as digital measurements and is furthermore combinable with a functional test at any time.

EOL / Functional test

In case successful ICT tests are followed by downstream process steps, we generally carry out an End-of-Line test. Consequently, each component undergoes an operational check by means of a function tester. These test and inspection devices are designed and realised by our experienced development team. Thanks to our long-term partnerships with selected suppliers, we always work with state-of-the-art function testers.
