Metal-ceramic joint

摘要

A process is described for electrolessly depositing or electrodepositing a solder layer composed of copper and silver and having an overall composition of silver/copper of from 75:25 to 70:30 and a total layer thickness of 15 to 100 mu m on a metallized ceramic. In this process, copper layers and silver layers are deposited alternately on the metallized ceramic. The number of layers is at least 3 and the individual layer thickness is 5 to 10 mu m.
