Abstract
Abstract An electronic sub-element is provided having a particular circuit configuration, and which in conjunction with other similar sub-elements of the same or different circuit configuration, may be adhesively attached to a panel-like base member so as to constitute a printed circuit assembly. The electronic sub-element of the invention is in the form of conductive metallic particles which are adhesively attached to a carrier strip, such as plastic or wax paper, and which form a multiplicity of electrical conductors separated from one another, the particles being intermixed with adhesive material.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
73 words
A sub-element for use on an electronic circuit board comprising: a carrier strip, a multiplicity of electrical conductors on said strip in the form of electrically conductive particles and intermixed adhesive material for causing said particles to be adhesively attached to said circuit board, and a release agent mounted on said carrier strip and interposed between said carrier strip and said electrical conductors and responsive to heat to release the electrical conductors therefrom.
Claim 2
Dependent Claim
73 words
A sub-element for use on an electronic circuit board comprising: a carrier strip, a multiplicity of electrical conductors on said strip in the form of electrically conductive particles and intermixed adhesive material for causing said particles to be adhesively attached to said circuit board, and a release agent mounted on said carrier strip and interposed between said carrier strip and said electrical conductors and responsive to heat to release the electrical conductors therefrom.
Claim 3
Dependent Claim
73 words
A sub-element for use on an electronic circuit board comprising: a carrier strip, a multiplicity of electrical conductors on said strip in the form of electrically conductive particles and intermixed adhesive material for causing said particles to be adhesively attached to said circuit board, and a release agent mounted on said carrier strip and interposed between said carrier strip and said electrical conductors and responsive to heat to release the electrical conductors therefrom.
Claim 4
Dependent Claim
73 words
A sub-element for use on an electronic circuit board comprising: a carrier strip, a multiplicity of electrical conductors on said strip in the form of electrically conductive particles and intermixed adhesive material for causing said particles to be adhesively attached to said circuit board, and a release agent mounted on said carrier strip and interposed between said carrier strip and said electrical conductors and responsive to heat to release the electrical conductors therefrom.
