Substrates

To integrate your unpackaged LED die or SMD, MARUBENI-OPTO™ products include a variety of solutions including metal-core PCBs that can be printed and etched to your circuit schematic/layout or advanced substrate designs that can be used for thin or thick film defined circuitry. Our ceramic products include aluminum nitride, which is approximately 7X more thermally conductive than alumina ceramic, as well as a compound Aluminum/Ceramic hybrid material that features low thermal coefficient of thermal expansion, high heat conductivity, high strength, lightweight and is an ideal alternative to typical ceramic or metal substrate products.

 

A highly thermally conductive insulated metal substrate (IMS) 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.

HIT PLATE
