Abstract
Abstract A patternable bonding material for joining the surfaces of two or more substrates permits localization of conductive or insulating hard-cored particles within an adhesive matrix to form patterned structures on or between the surfaces. Electrical, thermal, or mechanical energy may be transferred through, or isolated by the material. The material may be used in an uncured state to allow easy separation of the joined surfaces, or a more permanent bond may be formed. The adhesive may be cured by thermocuring, evaporation or ablation of organic components, pressure, or by the application of ultraviolet radiation.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
176 words
A joint between the surfaces of at least two substrates, having selected electrical properties, comprising: an adhesive binder that is curable by a one or two-step process, said adhesive binder comprising one of a thermally conductive, thermally insulative, or electrically conductive material, or a material for spreading or concentrating mechanical stress, wherein said adhesive forms a temporary bond prior to curing and a permanent bond subsequent thereto; a plurality of hard particles dispersed within said binder to form an adhesive matrix adapted to join said surfaces by selectably forming either of a temporary or permanent bond between the surfaces, the adhesive matrix being patterned by direct application upon at least one of said surfaces such that the particles within the adhesive matrix are brought into non-penetrating, non-bonding contact with said surfaces such that said matrix provides localized regions of communication between said surfaces across said bond, wherein said communication is primarily capacitive or resistive in nature, the value of which is determined by the size of the localized region and the constituent components of the material.
Claim 2
Dependent Claim
176 words
A joint between the surfaces of at least two substrates, having selected electrical properties, comprising: an adhesive binder that is curable by a one or two-step process, said adhesive binder comprising one of a thermally conductive, thermally insulative, or electrically conductive material, or a material for spreading or concentrating mechanical stress, wherein said adhesive forms a temporary bond prior to curing and a permanent bond subsequent thereto; a plurality of hard particles dispersed within said binder to form an adhesive matrix adapted to join said surfaces by selectably forming either of a temporary or permanent bond between the surfaces, the adhesive matrix being patterned by direct application upon at least one of said surfaces such that the particles within the adhesive matrix are brought into non-penetrating, non-bonding contact with said surfaces such that said matrix provides localized regions of communication between said surfaces across said bond, wherein said communication is primarily capacitive or resistive in nature, the value of which is determined by the size of the localized region and the constituent components of the material.
