Dr. Bob Q&A about Corrosion Dr. Mroczkowski, my question is this… In your recent articles in ConnectorSupplier.com (and in similar papers from your AMP days) you have basically stated that the reason interface resistance is lost when corrosion enters the picture is because corrosion films and contaminants compromise the asperity interfaces. However, I’ve never beenRead More

Connector Basics: Connector Degradation Mechanisms—Corrosion Part II This is the third article in a series on connector degradation mechanisms and the second article focused on corrosion. Tin-to-tin contact interfaces and fretting corrosion, as the dominant degradation mechanism in such systems, was the focus of the previous article. Now, we will address corrosion effects on contactRead More

Connector Basics: Connector Degradation Mechanisms—Corrosion Part I This is the second article in a series on connector degradation mechanisms. Corrosion, in general terms, followed by a discussion of a particular corrosion mechanism, fretting corrosion, will be the focus of this piece. Last month, we studied the asperity or a-spot model of a contact interface. InRead More

Dr. Bob on Connector Degradation Mechanism This is the first in a series of articles about connector degradation mechanisms. The purpose of this article is to provide a rationale as to why they are important to connector performance. Following articles will discuss degradation mechanisms in additional detail. At the end of this article, you willRead More
