Conventional testing of the assembly of nanocontacts (airbag net) using the push-pull method requires a lot of time and personnel, is prone to errors and cannot be documented. We have taken up this challenge and developed a testing system based on camera detection. In doing so, we have achieved the following objectives:
– Significant reduction of the cycle time, testing a connector with 140 contacts takes approx. 25 seconds (including evaluation).
– Parallel detection of other defect patterns is possible without any negative influence on the cycle time, e. g. deformation of pin contacts or damage to the contact housing.
– Tests can be repeated and documented
– A statistical evaluation of the frequency of different defect patterns is carried out for each specific position and thus enables an evaluation of the pre-processes.
