SiC wafer(substrate) - Latentek

–SiC is intrinsically very thermally conductive. Where a Silicon device will have to be cooled down to not exceed 85°C, a similar SiC device will operate at 250°C with no degradation. This robustness to higher operation temperature will allow cost savings at system or module level where the cooling features (air, water, fans, heat sinks.) will be considerably reduced and shrunk.

A New Grinding Force Model for Micro Grinding .

Therefore, this study developed a new grinding force model for micro-grinding of reaction-bonded silicon carbide (RB-SiC) ceramics. First, the grinding force components and grinding trajectory were analysed based on the critical depth of rubbing, ploughing, and brittle fracture. Afterwards, the corresponding individual grain force were established and the total grinding force was derived ...
