Whatsminer KF1960 ASIC Chip for M30S M30S+ M30S++ M31S Hashboard

Whatsminer KF1960 ASIC Chip – M30S / M30S+ / M30S++ / M31S Hashboard Replacement

The KF1960 is the MicroBT ASIC hashing chip used across the Whatsminer M30S, M30S+, M30S++ and M31S hashboards. When one or more chips fail, the affected hashboard loses hash rate proportional to the number of dead chip positions. This is a new original KF1960 chip — a direct SMD replacement that restores the chip position's contribution to the board's total hash rate output.

When to Replace a KF1960 Chip

The miner's ASIC status page shows each chip's operating state. A failed KF1960 appears as a missing position, an error flag or abnormally low hash rate at that slot. Common causes include thermal degradation from sustained high-temperature operation, solder joint fatigue under thermal cycling and electromigration in the chip's power rails. Replacing the failed chip with a new KF1960 and reflowing with fresh solder paste restores normal operation.

Replacement Procedure

Remove the hashboard and identify the failed chip from the miner log. Preheat to 150–180°C, apply flux and remove the chip with hot air at 350–400°C. Clean pads with solder wick. Apply solder paste using a KF1960 stencil, place the new chip with pin 1 aligned and reflow. Verify the chip appears in the hash chain and reports normal hash rate in the dashboard.
