Claim:
1. A method for electrically contacting terminal faces of two substrates, said method comprising: providing a first substrate with terminal faces facing a second substrate, wherein the terminal faces of the first substrate are provided with a soldering agent; positioning the terminal faces of the first substrate against terminal faces of the second substrate; applying laser energy to a rear of the first substrate in such a manner that the soldering agent is melted at least to such an extent so as to enable a mechanical fixation of the first substrate on the second substrate and an electrical contacting of the terminal faces facing each other; applying a flux medium, in a housing interior, to a component arrangement formed by the first and second substrates; simultaneously with the step of applying the flux medium, re-melting the soldering agent using laser energy applied to the rear of the first substrate; and subsequently rinsing the housing interior.
