Abstract (en)

[origin: WO0176334A1] The inventive method provides solderable areas in addition to bondable areas on circuit carriers, wherein solderability is not impaired by exposing the circuit carriers to the effects of temperature. The inventive method comprises the following steps: solderable surfaces are produced by deposition of a solderable metal layer (5), the solder areas are covered by a mask (6), functional surfaces (7, 8) are created in the functional areas and the covering mask (6) is finally removed.
