DCB & AMB Substrates

Application of Thermo-electric module Manufacturing Technology for Heat Dissipation and Insulation Substrate

Generally, organic and metal substrates are used in the circuit boards of low-power home appliances and computers.
However, alumina, aluminum nitride and silicon nitride substrates are used in heat radiation insulated substrates of power modules that handle high power.
In particular, silicon nitride substrates are attracting attention for use in power modules of inverters and converters because of the increase in sales of HEVs and EVs.
In response to this, we have started mass production of AMB (Active Metal Brazing) substrate as a new product, in addition to the DCB (Direct Copper Bonding) substrate that we have been producing.
Further development of the product is expected to contribute to miniaturization and energy saving.
