We offer high-quality KF1921 ASIC chip tin tools for repairing the chipsets on the Whatsminer M20, M20S, M21, and M21S. The complete set of tinning tools includes a tinning tool base, cover, and tinned stencil, which allows for quick repairs and replacement of chips. The tin stencil has ultra-high precision and is punched with a laser CNC machine tool. This results in tin-plated holes that are round without burrs and accurately positioned chip feet. Not only does this protect the chip, but it also ensures that the stencil is more durable.
