Cleaning of DCBs / DCB substrates and hybrids


Direct
copper bonding
(DCB) substrates are often used due to their good thermal conductivity in high-performance modules. They consist of a ceramic substrate board, usually alumina or aluminum nitride and usually applied with a copper foil on one or both sides in a high temperature oxidation process. Precisely because of the high power requirements (DCB substrates carry currents up to several thousand volts at temperatures up to 200° C), these components must be absolutely free of production residues for further working processes such as wire bonding, coating or varnishing.

The thorough removal of flux residues, colophony, resin, oxides and soldering materials are the main tasks when DCBs cleaning, PCB assemblies and hybrids so that for any following production step process-safe products can be provided.

kolbprovides for the cleaning of DCB substrates the complete cleaning process as a manufacturer from a single source: including machinery, accessories, cleaners and specially applied electronic process control.
