  • characterization
  • test program conversion
  • modification and optimisation of test solutions, e.g. test time reduction

electrical test for qualification and failure analysis

Qualification & Reliability investigations

Product Qualification and Environmental Tests

 

product qualification = advanced long-time reliability = minimization of failure costs

 

We perform customer specific qualifications and according to standards such as AEC-Q100/101/200, ESCC 9020/9010, MIL-STD 883/202, JEDEC 020, TELCORDIA GR 468/1221/326/1312, IEC 60 068-2-XX and DIN.
