Contamination Investigation on PCBs

PCBs (Printed Circuit Boards) are critical components at the heart of all electronic devices. The quality and reliability of PCBs have a major controlling effect on the quality and reliability of the overall piece of equipment. However, PCBs must be manufactured at a competitive price point and with significant industrial focus on mass production and cost reductions, many failures are reported during the production/testing of PCBs due to contamination. This makes finding and identifying contaminants an essential process for the determination of failure root cause.

By downloading this application note you will learn:

  • The use of EDS for elemental analysis
  • To determine whether the contaminant is organic or not, what elements are present and its quantified composition
  • The use of EDS for the determination of the thickness of the contamination on the surface of the PCB
