CUSTOMER PROBLEM
What made the part difficult?
The contact area is limited, nearby geometry can interfere with assembly, and the liner must be easy to remove without deforming the copper foil.
HOME/CASE STUDY
Copper foil grounding part for a compact electronic assembly
A thin converted part used to create a repeatable grounding path where board, housing and cable space compete.
