As a conclusion, the new antiparticle contact can reduce significantly any failure linked to particle
inside the switch. This improvement is a major step to go toward zero defects on the KSC series.
3. Change impact and qualification method
The design constrain for this new central contact on the lead frame and the new housing was to get no
modification on any specification to avoid any change on customer application. All product
features, mechanical, electrical, environmental remains unchanged.
The manufacturing & quality processes, location and procedures remain also unchanged.
The qualification proceeds as follows as both modification are dissociated.
You will find in annex 2 the justification of the characteristics choice for the qualification.
You will find in annex 3 a synthesis with all the part numbers test for the antiparticle contact and the
corresponding report for each of them. The full qualification report for the new housing is also included
in annex 4.
