Abstract (en)

[origin: WO2017167502A1] The invention relates to an adhesive for connecting a ceramic substrate, in particular a power-electronic assembly, in a heat-conductive manner, to a heat sink, and to a composite made of a heat sink and a ceramic substrate comprising the adhesive. By using hybrid metal-organic compounds and/or water glasses as the adhesive, high degrees of crosslinking are achieved and/or by means of the formation of covalent bonds between the adhesive and the joint partners and/or the filler particles, a clear increase of heat conductivity is achieved such that the heat-conductive adhesive layer exhibits a heat resistance which is substantially reduced compared to the prior art, and thus the heat dissipation chain is loaded less heavily than when using conventional joining and/or connecting methods.
