Testing technology

In the in-circuit test, assembled printed circuit boards or electronic components are contacted and tested for defects in the circuit path, such as short circuits or interruptions, solder bridges, and component defects.

In the process, each node in the circuit is tapped via a test needle. “Bed-of-nails test fixtures” are employed for the automated contacting of these test points.

During production, the quality of the devices or assemblies must be checked either in intermediate steps or at the end of the manufacturing process.
For the functional test, existing interfaces that are externally accessible (e.g. connectors) are generally used for this purpose. Special test fixtures are used for contacting.

This makes it possible, for example, to check sensors or controllers.

Together with our partners, we offer integrated solutions for flashing your products.

For flashing, the product-specific software is installed in the product. Alternatively, we also integrate your customer-specific system into our test systems.

We offer the flash process with our standard products as well as an integrated process for your specific solution.

For the final complete functional test of finished products and assembled components, we offer end-of-line test systems. This is the test performed at the end of a production line.

For this purpose, various environmental conditions may have to be simulated. Processes such as the application of labels are also checked.
The EOL testers can be configured for any requirement and provide traceable test results.

To ensure product functionality, we integrate haptic testing into our automation solutions.
The end customer touches and operates the product, while our test equipment ensures the proper feel and function.

Be it a button, a knob or a touch surface – we ensure its function with precision.

Test systems for high-frequency devices are used for testing products employing radio transmission.

The systems are designed for modules with frequency ranges from 300 MHz to 96 GHz. In addition to communication modules, these also include products with radar sensors for autonomous driving and car communication.

To rule out interference during testing, the test area must be shielded against external influences such as mobile radio communication or other interference pulses.

Defects that occur under extreme loads should be detected as early as possible in manufacturing processes. This is made possible by “temperature tests.” To perform these tests, the products are tested in the temperature test systems by being exposed to various thermal and mechanical stress factors, depending on the requirements.

Our product range includes both stand-alone systems (test chambers) and automated simulation lines.

ENGMATEC develops and implements reliable contacting for high voltages and currents of up to 1000 V and 400 A. Such contacting is of increasing relevance, especially in the areas of electromobility, battery management systems, and drive technology.

They are required, for example, for testing inverters, DC/DC converters, and drive controllers.

Optical systems are frequently used in modern test and assembly equipment.

From simple or complex detection tasks to quality checks and intelligent camera technology, we will work with you to determine the right system to meet your requirements and select the components accordingly.

Example applications include wobble circle tests, testing of component features, and camera-supported joining processes.
