Metalization of AM manufactured ceramic electronic components

Purpose and goal

The aim to identify possible methods for complete and selective metallization of ceramic 3D surfaces for electronics applications could be met through literature studies, project participants´ experience and market knowledge including business contacts and initial experimental trials. Favorable conditions exist for further development of complete metallization of additively manufactured microwave antennas with complex geometry by electroless plating whereas patterning of 3D surfaces requires more extensive investigations and need of international cooperation.

Expected results and effects

AM (stereolithography) of complex ceramic antennas is possible but problems with cracking at debinding require more development. Investigation and conducted experiments on complete metallization of ceramic antennas for microwave applications suggest PVD or electroless (electroless) plating, the latter suitable for interior complex geometries. For the selective metallization (patterning) of 3D surfaces are a number of methods including machining (mechanical power laser) of entirely coated surfaces or photolithography appear most interesting for further investigation.

Planned approach and implementation

This preliminary study was initiated with a workshop on additive manufacturing and metallization of ceramics for electronic applications where the project participants participated. Literature studies, participant´s experience/skills and market knowledge, own investigations including business contacts on the metallization side regarding complete or selective metallization of ceramic 3D surfaces and initial experimental metallization attempts led the project to adequate conclusions for future development directions within the field.
