Patent ID: 7951301

Claim:
A method for producing a circuit board comprised of a ceramic substrate comprising, on a top side thereof, solderable contact pads for contacting components, the ceramic substrate comprising solderable contact pads on an underside thereof, the ceramic substrate comprising ceramic layers, the ceramic layers comprising interlayer interconnections between solderable contact pads on the top side and the underside, the method comprising: depositing a metal from a solution directly onto the ceramic substrate to produce a base metallization layer for solderable contacts pads; structuring the base metallization layer to produce a structured base metallization layer; depositing a reinforcing layer above the structured base metallization layer; and applying a bondable layer above the reinforcing layer; wherein depositing the metal comprises: depositing a copper layer above the top side of the ceramic substrate; and reinforcing the copper layer galvanically; wherein reinforcing the copper layer comprises: depositing a nickel layer above the copper layer; and applying a palladium layer above the nickel layer by chemical deposition.
