ECB failure analysis

For ECB failure analysis in the testing center the following physicotechnical control methods are used:
  • optical microscopy;
  • X-ray inspection;
  • acoustic microscopy;
  • electronic microscopy;
  • electron microprobe analysis;
  • mass spectrometry;
  • foreign particles control (PIND test)
  • leak check (large and small break methods)
