Input Systems / Qualification

Qualification


So that your visions can be realized as an innovative input system our Business Development Team, equipped with a highly modern qualification laboratory and experienced engineers, are at your disposal. New procedures and materials are tested for process security before they are integrated into the processes.


Summary

Laboratory

The qualification laboratory at SCHURTER is equipped with the most modern test devices. The tests are carried out in constantly monitored and controlled room conditions. Even in the development phase we define physical and chemical parameters such as the force-displacement curve, viscosity of liquids and their wetness behavior on surfaces. Before mass production SCHURTER products are analyzed extensively in climate cabinets, in life-cycle tests and in the EMC laboratory comprehensive qualification tests and documented in test reports according to VDA standard.


Lifetime

In life-cycle test facilities our input systems are tested with multiple million switching cycles under defined mechanical and electrical load. SCHURTER products are tested way over the specified operational life cycles. Several test facilities run around the clock and therefore guarantee the highest reliability for the product.


Climate

For environmental simulations we use our climate cabinet with a temperature of -70 ºC to +180 ºC. Requirements of the automobile industry and medical technology are therefore covered. On request, we can also expose our products to more severe environmental conditions.

Ice cold and extreme humidity intensify the conditions for electrical components and housing materials. With data from the climate change tests, artificial aging processes can be simulated, which gives information about the expected operating life under real conditions.


Adhesive

When new materials and processes are introduced they are qualified with modern equipment. By using viscosimeters, calorimeters or surface tension measuring devices the appropriate examinations are carried out. With their deep knowledge of the wetness characteristics of various materials our engineers can ensure that we can guarantee invariable adhesion in paint, foils and adhesives.

Whether upon delivery or in the manufacturing process, our experts in laboratory measure and control the adopted materials, so that the highest quality is ensured.

Curing

To determine the degree of hardness of UV-potting the integration of the materials is verified with the calorimeter.


Wetting

The wetting characteristics of liquids compared to solids affects the quality of products and their production processes. Examples include the use of colors and varnish or the adhesion of materials. The wetting characteristics and the adhesive strength of colors and adhesives to foils or other substrates can be determined by defining the surface tension.

Due to deep knowledge of the wetting characteristics of various materials our engineers and technicians can ensure that we can guarantee consistant adhesive strength for colors and foils.

Microscopy

The most up-to-date digital microscopes enable us to see our products closely with a 1000-fold magnification. Our qualification team delivers the results to guarantee you, as a customer, the highest quality.

SCHURTER tests the products from the development process very carefully and extensively. Customer-specific product developments are carried out according to the ISO/TS 16949 standard and documented with information from the initial samples according to VDA standard. If desired we offer more qualification tests and create the appropriate test reports. If necessary, independent test institutes are consulted to verify the test results for you.


Haptics

One of the key parameters for input systems is the switching characteristic of the touch points, represented as force-displacement curve. Tactility means tactile sensation of the skin. The collection of test series in combination with the PC-analysis is an important contribution to a consistent tactility of all touch points on a control panel.


Geometry

In order to test with the same benchmarks, SCHURTER is geared to the same test equipment and carries out the same test procedures as our customers and vendors. A high-precision 3D coordinate measuring machine measures components exactly to the micrometer such as housing for initial sampling and later mass production. According to your requirements components can be tested optically or tactily. Flatness and coarseness can also be measured exactly and illustrated graphically in 3D.
