Abstract:
A method for thermal connecting the terminal areas of a contact substrate to the terminal areas of a carrier substrate, the method comprising the steps of:depositing adhesive material between the substrates in the plane of the connection; arranging the substrates in a connecting position such that the terminal areas are situated opposite one another in the plane of the connection and substantially simultaneously displacing the adhesive material deposit arranged between the substrates in the plane of the connection with the arrangement of the contact substrate in the connecting position, said arranging of the substrates and said displacing of the adhesive simultaneously scaling a gap between the substrates; heating the contact substrate to the connecting temperature from a rear side that is situated opposite the terminal areas in order to reach the required connecting temperature in the plane of the connection; and hating the contact substrate by subjecting the substrate to laser energy to produce a thermal connection between the terminal areas of the substrates.
