We consider the future test strategy in the design phase and implement it in parallel with production. Among other things, during the development phase, we think ahead to consider the test contacts for the test fixture. An ICT test without test contacts is also possible. Our forethought helps to avoid the need for expensive corrections or additional production steps.

What do we take care of from the very beginning? Among other things, making sure the outside edges of circuit boards benefit production, thinking about how a housing can be perfectly planned in, working out where connectors will be a nuisance or where wide mechanical tolerances can be permitted. For decades, we have developed and produced together under one roof. Engineering in a way that benefits manufacture is part of our company DNA.
