T19 scrape silicone grease mold is one of the essential tools for modifying the T19 hash board to upgrade the heat sink. Before assembling the upgraded heat sink, we need to smooth the surface of the ASIC chip so that the thermal grease can better cover it. And this tool can help the chip to easily apply thermal conductive silicone grease, high grinding efficiency, accurate positioning, not easy to damage other components of the hash board, and increase the coverage of silicone grease, thereby improving the success rate of installing and upgrading heat sinks and reducing operation and maintenance costs.
