Purpose and goal

Graphene coated particles as conductive materials in ACA. These have sufficient mechanical strength for processing in highly viscous adhesives and have good conductivity. The production has been scaled up for volumes for testing. Anisotropic conductive adhesives based on the particles have been evaluated for flip-chip assembly of the ScandiDos detectors. A market study for these adhesives has been made. Long term, the project result enable low cost assembly of sensors with adhesives that minimize secondary radiation.

Expected results and effects

The project has developed anisotropically electrically conductive adhesives based on graphene-coated polymer particles. A wet-chemical method for creating coatings of graphene on spherical polymer particles has been developed. The method is scalable. Equipment has been built for fabrication. A method has been developed for drying the particles and for dispersing them in adhesive bases. A binder system has been developed for prototype mounting with the graphene-coated particles. Prototype assembly of components with the particles shows that the adhesive works as intended.

Planned approach and implementation

Partners: Aktörer: ScandiDos AB, Akzo Nobel AB, Mycronic AB, 2DFabAB, RISE Acreo AB The project started by developing a scalable method for graphene coating on polymer spheres and equipment for it. A system for adhesives with latent curing was developed to facilitate development of conductive adhesives, including a method to disperge the particles in the adhesive prior to tests of electrode material before assembly.
