Whatsminer KF1958 Chip Tin Tool Stencil for M30s M30s+ M30+ Hashboard

KF1958 Chip Tin Tool Stencil – Precision ASIC Repair for Whatsminer M30s, M30s+ & M30+ Hashboards

This 75 × 75 mm tin stencil is purpose-built for reballing and replacing the KF1958 ASIC chip on Whatsminer M30s, M30s+ and M30+ hashboards. Manufactured using high-speed numerical control and laser-cut from thickened steel plate, it provides precise hole positioning that ensures uniform solder-ball placement on every chip — reducing rework rates and cutting repair time compared to hand-soldering methods.

How to Use the KF1958 Tin Stencil

After removing the defective KF1958 chip from the hashboard with a hot-air station, clean the chip site pads thoroughly using flux and solder wick. Place the new (or known-good) KF1958 die into the stencil with the correct orientation. Apply solder paste across the stencil openings using a squeegee, ensuring every aperture is filled evenly. Remove the stencil carefully to reveal uniform solder balls on the chip's BGA pads, then position the chip on the board and reflow using the standard KF1958 temperature profile.

The stencil's thickened steel construction resists warping even after dozens of reflow cycles, maintaining accurate alignment between the aperture pattern and the chip's pad array. For repair shops processing multiple M30s boards per day, this durability translates directly into consistent quality and lower per-board rework costs.

Choosing Between Tin Stencil and Tin Fixture

A tin stencil like this one handles the solder-ball application step — it deposits paste onto the chip's BGA pads before reflow. A tin fixture, on the other hand, holds the chip in position during the reflow process itself. For best results on KF1958 replacements, use both: the stencil for paste deposition and a compatible fixture for alignment during soldering. This two-tool approach is standard practice in professional mining hardware repair facilities.
