Case study
Fully automated testing of printed circuit boards
A customer came to us with an order for the fully automated testing of printed circuit boards. These form the core of a radar sensor and must therefore meet the highest quality and safety requirements.
Given the high volume in which they are manufactured, the main focus was on the cycle time, which had to be reduced as much as possible. The automation concept was further developed over several system generations, so that we were able to reduce the cycle time per individual printed circuit board to 3 seconds. Another advantage is that the complete line has a setup time of less than 10 minutes.
Due to the modular concept, a system for small volumes would also be feasible.
The concept is based on many years of experience and many generations of these lines. Exchangeable product-specific contacting allows different PCBs to be tested – whether for radar sensors, control units, or other electronics.

Our
services
To generate a cost-effective solution for the customer, ENGMATIC employed standardized board handling modules and test handlers and integrated depaneling machines. Various contacting concepts, such as full-surface contacting or step operation, were employed both to satisfy the cycle time requirement and to lower the capital expenditure.
