Vibration Test could simulate the various dynamic environments which products suffer in the field during transportation, installation, and each usage situation. This test is used to evaluate the reliability level of anti-vibration for the various product, and it is more important and critical for automotive electronics.

  Vibration Category 
  • Sine(Sinusoidal) wave Vibration: During product development stage, sine wave vibrations is normally used for being aware with the product design limitation of mechanical structure and accompanied with resonance search & dwell validation at specific frequency.
 
  • Random Vibration: Random vibration is mainly used for evaluating whole structural reliability level of the product during the diverse environments, and transportation situations under packaged conditions.
 
  • Specific Condition Vibration:For specific request from vehicle or military application, Sine-on-Random or Random-on-Random vibration tests are also considered for electronic products.
In general, the selection of vibration standards, are used ASTM, ista or MIL STD by most American clients, EN, IEC, ETSI, JIS by Japanese and European clients as reference. For the small device, such as: IC or passive component uses MIL STD and JESD as reference standards.
For automotive electronic products, the vibration requirements are much higher than consumer or information technology electronics, and special attention is paid to the combination stresses, such as temperature/humidity/vibration, during validation.

In addition to self-determined validation standards from automotive OEMs or tier 1 suppliers, there are lots of international standards for reference and adoption, include SAE, JASO, IEC and ISO standards for module or sub-system products, and AEC standards for automotive IC or passive components.

DEKRA iST has satisfied the request by diverse products and applications, from IC/passive component, modules, system products to large objects (over 500Kgs), with comprehensive and completely reliability capability.
