Stress relief material science.
This is primarily due to keeping the structure in a strained condition for some finite interval of time and hence causing some amount of plastic strain.
Ok you may ask but what does that have to do with connectors.
Their stress relief substrates have a unique structure and utilize pillar arrays to reduce the stress on the active areas of devices when strain is applied.
In the metallurgical world stress relaxation is defined as a time dependent loss in stress at constant strain.
Stress relaxation i mechanisms materials and temperature.

It s all about contact force.
Heat treating stress relief is used to reduce the internal material stresses within a part or assembly as a consequence of manufacturing processes.
Although it is impossible to measure the intensity of this stress.
In mechanics and materials science stress represented by a lowercase greek letter sigma σ is a physical quantity that expresses the internal forces that neighbouring particles of a continuous material exert on each other while strain is the measure of the deformation of the material which is not a physical quantity.
The contact normal force is a critical design parameter for connectors because.
Heat treatment stress relieving.
The difference between this embrittlement during pwht and service is not just one of time but also.
