Encapsulated Graphite Heat Spreader Boyd - Boyd Corporation
WebNov 18, 2024 · Although the stainless steel-copper-stainless heat spreader has 50 μm lower thickness, its thermal conductance (0.049 W/K) is nearly 20% higher than that of the stainless steel plus graphite heat spreader (0.041 W/K). This is due to the high thermal conductivity of the copper core in the clad heat spreader. WebIt is a high-performance, cost-effective graphite heat spreader that achieves higher thermal conductance than synthetic graphite, natural graphite, and metallic solutions. The product has superior repeated flexibility for demanding applications such as foldable screens in notebooks, tablets, and mobile phones. WebNov 17, 2024 · Graphite, with comparable thermal conductivity (1,500 W/m·K) along the basal plane, is advantageous as a heat spreader because it is significantly less expensive than diamond.7 Moreover, the hardness, fracture toughness, and mechanical strength of graphite are lower than those of diamond and enable its machining using simpler … how do you verify identity on venmo
