Panasonic Industry has developed an high-thermal conductive film named R-2400, designed explicitly for multilayer circuit boards. This innovative film stands out in the industry by achieving exceptional high-thermal conductivity of 2.7 W/m・K, alongside remarkable resin flowability, enabling the effective multilayering of circuit boards.
The R-2400 circuit board material effectively addresses the heat-related challenges caused by power semiconductors, surpassing the capabilities of conventional high-thermal conductive materials. Its application extends beyond traditional usage, making it suitable for component-embedded circuit boards and those incorporating thick copper foil. These attributes significantly contribute to reducing power consumption (electricity costs) in electric vehicles while simultaneously reducing CO2 emissions. This is achieved through weight reduction and the miniaturization of power supply modules and drives, facilitated by the film's unique features.
