Case Study: Failure Analysis for Electrical and Electronic Industry

Next up on the Failure Analysis blog series, we will explore the applications of Failure Analysis in the Electrical and Electronic industry. Read on as we share a case study from the industry.

INTRODUCTION TO THE FAILURE ANALYSIS CASE STUDY IN THE ELECTRICAL AND ELECTRONIC INDUSTRY

In this blog, we will look at a case where a satellite ground station experienced a malfunction and reached out to our Failure Analysis team for an investigation.

IDENTIFYING THE ROOT CAUSE OF FAILURE

With a strong background in the areas of electrical and microelectronics, the Failure Analysis team conducts investigations using state-of-the-art equipment and offer thorough analyses using instruments such as FE-SEM microscopes.

OUTCOME OF THE ANALYSIS

Through the investigation, the team found that the precise fault was an open circuit failure of a power distribution PCBA.

The cause of the failure was inadequate etching-back of the PHT (plated through-hole) following the drilling. This, in turn, resulted in improper Ni-plating and weak material bonding.

The Failure Analysis team therefore recommended the client to perform a more thorough cleaning process as this would have prevented the failure.
