The modern way of testing printed circuit boards (PCBs)

Control units for automotive safety systems must function perfectly under all conditions.

For this reason, one-hundred percent testing of the circuit boards used is mandatory. Thanks to robotics, this is now faster and more flexible than ever.

Robot-assisted testing of printed circuit boards

Human lives depend on the reliable functioning of electronic assistance systems.This has led one renowned automotive supplier to install a state-of-the-art, ultra-flexible inspection system for the 100% testing of PCBs destined for use in sensitive electronics applications. The system is even able to perform high-temperature tests at 140°C.

Electronic components and systems in motor vehicles are exposed to extreme temperatures. In order to ensure the proper functioning of components, these environmental conditions must be replicated in various test procedures. Early on, Amberg-based automation specialist Baumann GmbH focused on the design and construction of test systems for this purpose.

Baumann generally prefers to rely on the highly modular standard cells it develops in house. This was the case when the supplier received an enquiry from a multinational Tier 1 manufacturer about a fully automated line for circuit board testing at room temperature and above. Baumann’s engineers came up with an individualized standard solution.

The six-axis robot impresses in the test cell by virtue of its high dynamics and exemplary precision.

The complete test line consists of two linked test cells with docked test stations. The oven for heating the circuit boards is shown in the center of the photo.
