We create "heat dissipation substrates" that allow for the selection of substrate materials and configurations tailored to specific applications and heat dissipation challenges. Thick copper plated substrates form circuits for heat dissipation from heat-generating components directly to conductors and the back surface of the substrate through copper plating. In metal base substrates, a dielectric (insulation layer) and copper foil are laminated on copper or aluminum, and by connecting to copper or aluminum plates through filled vias, high heat dissipation is achieved. Additionally, we have extensive experience in the mechanical design and manufacturing of various heat dissipation carriers and enclosures, as well as the selection and assembly of heat sinks and TIM materials, allowing us to provide consistent support. 【Application Fields】 ■ High Frequency ■ Automotive ■ Power Modules ■ High Power LEDs ■ Inverters *For more details, please download the PDF or feel free to contact us.

With the energy-saving of devices and the low voltage of ICs, the use of DC/DC converters with excellent conversion efficiency is increasing. In recent years, DC/DC converters have become very frequently used due to improvements in several drawbacks, including high performance, high functionality, miniaturization, and reduction of external components. However, to effectively utilize them, it is important to minimize noise generation and reduce the impact of generated noise on other circuits. Therefore, assuming that the selection of peripheral components considering noise has been adequately done, we will verify "how much noise countermeasures can be achieved through substrate patterning" with practical examples. *For detailed content of the article, please refer to the related links.

An important factor in machine design, circuit design, and substrate design is "controlling heat." The heat dissipation path, from the perspective of thermal resistance, is significantly large, as heat conducted from components to the substrate wiring is transmitted into the air. With the recent trend of high-density integration of components and miniaturization of devices, the importance of measures through substrate patterning has been increasing. Here, we will introduce specific thermal countermeasures based on verification experiments regarding "how much difference substrate patterning can make in thermally demanding circuits." *For detailed content of the article, please refer to the related links.
