Abstract
Abstract A selectively releasing runner and substrate assembly 100 comprises a plurality of conductive runners 116 adhered to a substrate 112, a portion 118 of at least some of the conductive runners 116 have non-planar areas with the substrate 112. Additionally the portion 118 has a lower adhesion to the substrate for selectively releasing the conductive runner 118 from the substrate 112 when subjected to a predetermined stress.

Claim 2
Dependent Claim
91 words
A circuit-carrying substrate assembly, comprising: a substrate having a surface including a plurality of non-planar valleys extending into and below the substrate surface; and a plurality of runners attached to said substrate, a first portion of at least some of said plurality of runners having substantially less adhesion to said substrate than the rest, said first portion being at least partially disposed on said valleys, for providing said plurality of runners with a spring action in order to selectively release said plurality of runners from said substrate when subjected to stress.
Claim 3
Dependent Claim
85 words
A selectively releasing runner and substrate assembly, comprising: a substrate having a surface including a plurality of non-planar bumps extending out of and above the substrate surface; and a plurality of conductive metalized runners adhered to said substrate, a portion of at least some of said metalized conductive runners having substantially less adhesion to the substrate than the rest, the first portion being at least partially disposed on said bumps, for selectively releasing said runners from said substrate when stress is applied to said assembly.
Claim 4
Dependent Claim
85 words
A selectively releasing runner and substrate assembly, comprising: a substrate having a surface including a plurality of non-planar bumps extending out of and above the substrate surface; and a plurality of conductive metalized runners adhered to said substrate, a portion of at least some of said metalized conductive runners having substantially less adhesion to the substrate than the rest, the first portion being at least partially disposed on said bumps, for selectively releasing said runners from said substrate when stress is applied to said assembly.
