Patterned DCB substrates can be manufactured to customers‘ drawings.
DCB ceramic substrates fulfill several functions:
- carriers for the semiconductor chips and connection clips
- circuits similar to that on a PC board
- electrical isolator for separating the „current paths“ from the „heat paths“
- transfer medium for the heat dissipation from the active parts into the heat sink.
