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.
Claims11
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.
