Test- and Calibration solutions

One of our main areas of activity is the testing and calibration of products, mainly electronic components of all kinds. Starting with small LEDs with a size of 5x5 mm, contact areas of 0.5 mm, and contact pins with a diameter of 0.3 mm, to components from e-mobility such as Eg batteries with a size of 1x2m and 100 kg or e-mobility control units with currents of up to 800A.

As well as tests in the optical (AOI, spectral measurement, ...) and mechanical (force, displacement, ...) area.

The devices and machines for this range from simple manual devices to fully automatic, interlinked systems in which a wide variety of processes can be integrated.

We can implement the corresponding test software in a package together with partners.

Thermal test

Thermal test methods are the most suitable means of qualifying electronic products for use under extreme temperature conditions. We support our customers in choosing the most suitable method. Depending on the application, we develop static run-in systems or automated transfer systems.

Stahl MB has long been a specialist in the planning and execution of fully automatic tunnel systems (DTA). Our customers benefit from optimized processes that guarantee fast throughput times and process reliability at the same time.

In addition to the main process of electrical testing, further processes (link) can be integrated into these systems, such as marking stations or cleaning, in order to map individual customer requirements.

Application example Task:Electrical testing and stimulation of sensors of a transmission control in different temperature ranges - low temperature down to -40 ° C, high temperature up to + 160 ° and at room temperature

Technical implementation:

Staggered sequence of temperature tests in integrated test adapter chambers, including corner point tests

Fully automatic throughput with a workpiece carrier transfer system

Loading and unloading takes place automatically by means of a robot

Operation area:

Electronics manufacturing for automotive / aerospace, renewable energies

Burn-in, run-in and screening systems

In order to put electronic or electromechanical components into "stress", to uncover weak points or design errors, tests are carried out under the influence of high temperatures. These can also be expanded into service life tests. For this purpose, the components are fitted and contacted on so-called run-in boards and contacted with a test system via defined interfaces. In contrast to a continuous tunnel system, continuous testing is possible while the temperature changes. The lead time can range from a few hours to several weeks.
