Abstract
Abstract Ordered Z-axis electroconductive sheet materials are produced by entrapping bodies of fusible, polymeric, electroconductive adhesive at predetermined spaced locations in a sheet-like carrier of fusible, polymeric, dielectric adhesive including a thermoplastic component. The materials are useful for mechanically joining and electrically connecting electronic circuit components.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
86 words
A method of making a heat-bondable, anisotropically electroconductive, adhesive material, comprising the steps of: providing a carrier sheet of fusible, polymeric, dielectric adhesive including a thermoplastic component; forming holes at predetermined spaced locations in the carrier sheet; depositing a plurality of substantially spherical pre-formed bodies of electroconductive, fusible, polymeric adhesive in a substantially solid state on one side of the carrier sheet; drawing the bodies into the holes under suction applied from an opposite side of the carrier sheet; and entrapping the bodies in the holes.
Claim 2
Independent Claim
86 words
A method of making a heat-bondable, anisotropically electroconductive, adhesive material, comprising the steps of: providing a carrier sheet of fusible, polymeric, dielectric adhesive including a thermoplastic component; forming holes at predetermined spaced locations in the carrier sheet; depositing a plurality of substantially spherical pre-formed bodies of electroconductive, fusible, polymeric adhesive in a substantially solid state on one side of the carrier sheet; drawing the bodies into the holes under suction applied from an opposite side of the carrier sheet; and entrapping the bodies in the holes.
Claim 3
Dependent Claim
26 words
A method according to claim 1, wherein the electro-conductive adhesive includes a component selected from the group consisting of thermoplastic polymers and partially polymerized thermosetting resins.
Claim 4
Dependent Claim
16 words
A method according to claim 2, wherein the electroconductive adhesive includes an electrically conductive, particulate filler.
Claim 5
Dependent Claim
15 words
A method according to claim 1, wherein the dielectric adhesive includes a thermosetting resin component.
Claim 6
Dependent Claim
17 words
A method according to claim 1, wherein the dielectric adhesive includes a thermally conductive, dielectric, particulate filler.
Claim 7
Dependent Claim
25 words
A method according to claim 1, 2 or 4, wherein the bodies are entrapped in the holes by heating the bodies simultaneously with each other.
Claim 8
Dependent Claim
27 words
A method according to claim 1, wherein the carrier sheet has a thickness of from about 25 microns to about 250 microns in regions separating the bodies.
Claim 9
Dependent Claim
20 words
A method according to claim 7, wherein the bodies have a diameter greater than said thickness of the carrier sheet.
Claim 10
Dependent Claim
19 words
A method according to claim 1, 2, or 4, wherein the bodies are entrapped in the holes by heating.
Claim 11
Dependent Claim
32 words
A method according to claim 1, 2, or 4, wherein the bodies are entrapped in the holes simultaneously with each other by pushing the bodies into the holes with a heated platen.
Claim 12
Dependent Claim
27 words
A method according to claim 10, wherein the bodies are pushed into the holes such that they are proturberant from the opposite sides of the carrier sheet.
