• High thermal conductivity (a ;line up with maximum conductivity of 8W/mK)
• High reliability (voltage resistance, heat resistance, and heat shock resistance and durability)

In the field of power hybrid ICs, progress is being made every day in terms of miniaturization, higher degree of integration and higher power. These substrates require a higher degree of heat dissipation as well as higher reliability and processing power than their predecessors.

The “HITT PLATE” is a metal circuit board with high thermal conductivity, which has been developed using high thermal-conductivity technologies, consisting of an aluminum base, an epoxy-based insulation layer with a high inorganic content filler demonstrating high thermal conductivity, and a conductive foil, thereby realizing thermal resistance equivalent to, or less than that of an alumina ceramic substrate.

They are used in a wide variety of applications, including air conditioner inverters, stereo amplifiers, automobile and motorcycle electrical devices, and power supplies for communications equipment.

• Industrial electronic equipment (transistors and diode modules, step and servo motors, SSRs, etc.)
• Automotive electrical components (power driven power steering controller, inverter for (H)EV, etc.)
