Detailed information
-
AC-7900. Thermal conductivity of the insulation layer = 1W/mK. The insulation layer reinforced with glass fabric can be made as thin as 0.06mm, allowing for a reduction in thermal resistance, which is expected to provide better heat dissipation than the catalog values. The insulation layer is white and designed to minimize discoloration due to ultraviolet light and heat.
-
AC-7004C. Thermal conductivity of the insulation layer = 3W/mK. This is a long-selling product that has been refined over 20 years based on feedback from our customers.
-
AC-7302. Thermal conductivity of the insulating layer = 2 W/mK. A solder crack prevention product with a very soft insulating layer even after thermal curing. The soft insulating layer absorbs the thermal expansion (contraction) of the aluminum plate, reducing the stress on the solder joints of surface-mounted components.
-
AC-7303. Thermal conductivity of the insulating layer = 3 W/mK. A solder crack prevention product with a very soft insulating layer even after thermal curing. The soft insulating layer absorbs the thermal expansion (contraction) of the aluminum plate, reducing the stress on the solder joints of surface-mounted components.
-
AC-7200TY. Thermal conductivity of the insulation layer = 5W/mK. It has been widely adopted for high-brightness LED lighting applications.
-
AC-7210N. Thermal conductivity of the insulation layer = 10 W/mK. The insulation layer also has high heat resistance with a Tg of 300°C. We are considering its adoption around SiC power semiconductors.
-
Processed products made from aluminum base substrate materials (demo products). For explanation purposes, the insulating resin layer arranged on the surface of the aluminum plate has been removed to expose the underlying aluminum plate. Cooperation: Techno Electronics Co., Ltd.
