Abstract:
A solder deposit carrier for depositing solder deposits by electroplating in an array defined by mask openings and for transferring said solder deposits on terminal areas of a substrate, comprising on an electrically conductive, non-wettable or wetting-inhibiting coating a transfer mask of an electrically isolating, non-solderable material which exposes the coating in the area of mask openings, in which the mask openings serve to accommodate solder deposits electroplated onto the coating,wherein the coating (12) applied to a carrier structure (11) comprises two superimposed metal layers (15, 17) of different materials, such that the layer (17) facing towards the mask openings (14) is non-wettable or has a wetting-inhibiting effect, and the layer (15) arranged facing away from the mask openings (14) acts as a current-carrying layer during the electroplating.
