Dcb substrates direct copper bond or dbc substrates direct bond copper or cpc substrates copper plated ceramic thin film circuits thick film circuits and pctf plated copper on thick film substrates are in the power electronics led technology led submount and laser diode technology laser diode submount due to the small size mechanical strength and good.
The role of the substrate in power electronics is to provide the interconnections to form an electric circuit like a printed circuit board and to cool the components compared to materials and techniques used in lower power microelectronics these substrates must carry higher currents and provide a higher voltage isolation up to several thousand volts. Product ceramic pcb dcb ceramic pcb dcb direct copper bonded sometimes also named as dbc direct bonded copper technology denotes a special process in which the copper foil and the al 2 o 3 or aln one or both sides are directly bonded under appropriate high temperature. The rf dcb ceramic pcb has great isolationg performance and thermal conductivity. Materials aluminum nitride and alumina ceramic pcbs are usually made of metal cores.
