Abstract (en)

[origin: WO2013164348A1] The invention relates to a method for producing ceramic circuit boards from ceramic substrates having metal-filled vias. In order to be able to fill the vias by means of a single filling process, either a planar copper metallization is applied on one side to the ceramic substrate having vias by means of screen printing, or a copper film of 100 - 300 mum is bonded on one side to the ceramic substrate having vias in a DCB/DBC process and the vias are filled from the ceramic side by means of an electrogalvanic process in a copper bath by the deposition of copper.
