An experienced, in-house team of test and analysis specialists stands for the peak of quality – product-specific and exactly as you, the customer, desire it. To ensure quality in serial manufacture early on and guarantee a frictionless start of production, test equipment is incorporated into manufacturing processes and automated production lines. Test contacts on the circuit board, produced for just this purpose, are contacted by fine, spring-loaded test pins. Depending on the series size, the in-circuit test can take place manually or in an automated fashion. In combination with other test processes, including tests without test contacts, over 90 percent of all errors can be detected.

Our production facilities are fully up to date. Thanks to the adjustable design of our lines, we can easily implement special solutions. We have the latest generation Rehm reflow soldering systems. In particular with regard to temperature zones, they are exceedingly efficient. The soldering process takes place in a protective atmosphere. In the reflow soldering process, we process through-hole and SMD components. The number of work stages, sources of error and thermal loads is reduced. In the reflow process we are also able to solder through-hole components, thereby reducing sources of error and repeated thermal load and work stages.

Alongside the standard ICT/FCT process, we can also target every individual production stage for verification, as requested. Efficient inspection strategies and final functional tests are a fixed component of our quality management system. This electrical test process is ideal for testing smaller numbers of units, such as for pre-production, prototype or pilot series. The rapid test creation process allows, among other things, flexible reaction to product changes. Flying probe tests can be rapidly set up and are cost-efficient.
