Antminer S17 upgrades the positioning tool for the nut base of the radiator working plate. It is made of high-temperature resistant and bending-resistant materials, which is durable and accurate in positioning, ensuring that the connection between the nut and the hash plate will not fall off. Using the nut tinning jig, you can quickly tin the nuts of the entire hash board to ensure uniform tinning without causing false soldering or mis-soldering. It is one of the necessary tools for the S17 modified radiator.
