Liebherr Electronics Test Center
Throughout their entire service life, electronic products are subjected to a wide range of environmental influences, such as extreme temperatures, temperature fluctuations, vibrations or electromagnetic radiation.
With state-of-the-art testing and measuring facilities, Liebherr operates an electronics test center within the competency center at the Lindau site. By simulating the environmental influences, the quality and reliability of its electronic assemblies can be analyzed and improved right from the development stage. This enhances efficiency and extends the service life, and ensures the functionality of its equipment throughout the whole life-cycle.
Liebherr offers services at the highest level to customers from aviation and traffic engineering as well as the automotive and industry sector – from consultation to the execution of tests and product registrations. We carry out conventional environmental simulations for you and also customized tests in accordance with many international standards. An analysis laboratory for evaluation of the results and individual development services supplements our range of offers.
With over 140 members of staff, the committed development and testing team utilizes its wide-ranging expertise to realize innovative and economic solutions with you.
An overview of our services
Electromagnetic compatibility (EMC) tests are executed for you at the Liebherr test center according to the following standards (among others):
RTCA/DO-160, MIL-STD, CISPR 16 and CISPR 25, DIN EN 61000
- Resistance to interference from radiated emissions: 30MHz to 18GHz; up to 200V/m (from 100MHz continuous)
- Resistance to interference from conducted emissions: 10kHz to 400MHz; up to 300mA
- Radiated emissions: 9kHz to 18GHz
- Conducted emissions: 10kHz to 200MHz
Electrical tests are growing increasingly in importance for the registration of electronic products. Essentially, they can be grouped together as follows:
- Lightning-induced transient susceptibility
- Electrostatic discharge (ESD)
- Voltage transients (spike, surge, burst)
- Power input tests
- Standard for system perturbations, harmonic tests and flicker tests
By simulating the environmental influences, the quality and reliability of its electronic assemblies can be analyzed and improved right from the development stage. In this way, the efficiency and service life are enhanced and the functionality of your equipment is assured.
We can offer you the following tests:
- Climate tests
- Salt spray tests
- Infrared thermal analyses
Our temperature, moisture and shock chambers offer you a broad spectrum for environmental simulations.
By inducing stress beyond the specified values, mechanical or electrical breakdown is engineered. The analysis of this contributes towards product improvement.
Salt spray tests:
Our 1,000l salt spray chamber is available to you for corrosion testing.
Infrared thermal analysis
With the aid of our thermal cameras, we find hot and cold spots on test objects.
The constantly rising demands on the mechanical reliability of electronics equipment necessitate comprehensive vibration and shock tests. In the Liebherr test laboratory there are two electrodynamic vibration testing systems available for this purpose, which can be used not only for development purposes but also for qualification.
- Random / sine / shock
- Resonance dwell
- Combined tests (Sine on Random noise, multiple sine)
- Temperature cycling
55kN shaker plant
With optional temperature cycling and maximum 3inPk-Pk oscillation, we cover a broad portfolio of tests with this facility.
35kN shaker plant
The slightly smaller shaker plant is an excellent facility for the qualification of components.
Whether you wish to analyze materials or understand complex correlations, our analysis laboratory is available to you to perform your tests competently. The laboratory is equipped with the latest technology to offer the following options for development-related examinations, special analyses as well as series monitoring:
- X-ray examinations
- X-ray fluorescence spectroscopy
- Semi-conductor industry
- Section preparations
- Optical examinations
- Electrical and functional fault analysis on components
- Electrical component measurements
- Electrical parameter testing on components
You can perform a wide range of complex measuring tasks directly on-site with competent support from our members of staff.
The process of micro-sectioning is divided into individual steps: separating, embedding, cutting and polishing. The sample is prepared by means of a cold mounting process
3D X-ray computer tomography is employed for more extensive analysis. The ultra-high resolution sectional images and slices can be created from almost all mechanical and electronic objects and used for fault analysis.
In addition to individual tests or complete analyses of your electronic assemblies, Liebherr also offers you individual development services. We accompany and support your product development from the concept to series production and beyond.
