Connector Basics: 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 will be able
to provide feedback on this subject and also be able to
participate in an online discussion with others in the industry.
If you have specific questions regarding future topics, email
them to

Connector
Basics:
Connector Degradation Mechanisms—Corrosion Part I
The kinetics of corrosion mechanisms in connectors can be very
complex, but for the purposes of this discussion, two such
mechanisms will be highlighted: surface corrosion and
motion-induced corrosion, or fretting corrosion. What can be
done about it? There are two general approaches to fretting
corrosion prevention, one directed at preventing fretting, and
one at preventing corrosion.

Connector Basics:
Connector Degradation Mechanisms—Corrosion Part II
The importance of a nickel underplate in gold-plated connector
systems cannot be overemphasized. Why is nickel underplate so
important, and what effect does it have on corrosion
degradation? more
Connector Basics
Connector Degradation Mechanisms: Wear
There are two primary mechanisms that cause wear in connectors.
The most obvious one is the wear that occurs each time the
connector is mated. The second mechanism is wear that occurs due
to fretting motions during the application life of the
connector. What can you do to offset wear?

Degradation Mechanisms: Loss in contact normal force.
The degradation concern for contact force loss is addressed by
proper material selection to counter the effects of stress
relaxation, and by proper mating practices to prevent
overstressing of contact beams during application of the
connectors. These issues are important because of their
potential impact on connector susceptibility to micromotions.
Dr. Bob explains how to do this.
