Whatsminer KF1930 Tin Tool - ASIC Chip Replacement Set for M30 Hashboard

Whatsminer KF1930 Tin Tool Kit | ASIC Chip Replacement Set for M30 / M31 / M32 Hash Boards

The Whatsminer KF1930 tin tool kit is the complete reballing fixture for the KF1930 ASIC chip — the SHA-256 hashing chip used across an unusually wide range of Whatsminer generations. The KF1930 chip fits M20S, M30, M30S, M31, M31S, M31S+, M32, M32S, and M3x / M3xS hashboards. The Whatsminer M32 (68 TH/s at 3400W, 50 J/TH, released October 2021) and the M30S++ are the most common deployment targets. One tin tool kit covers ~9 different Whatsminer SKUs.

The kit pairs a high-temperature resistant composite stencil with an anti-static chip holder. The composite material outperforms standard alloy stencils on two counts: (1) zero electric-charge buildup against the KF1930's CMOS gate structures during paste application, (2) better dimensional stability through repeated reflow cycles at the elevated peak temperatures BGA reballing requires.

Where the KF1930 Tin Tool Kit Fits

• Whatsminer M30 / M30S / M30S++ — primary application, SHA-256 BTC mining.
• Whatsminer M31 / M31S / M31S+ — same chip family.
• Whatsminer M32 / M32S — 68 TH/s @ 3400W class miners.
• Whatsminer M20S — legacy generation, also uses KF1930.
• M3x / M3xS broader family — confirmed cross-compatibility for KF1930 chip family.

Construction and Materials

• High-temperature resistant composite — survives SAC305 reflow profiles without warping.
• Anti-static composite chip holder — prevents electric-charge buildup against the KF1930's CMOS gates.
• Complete kit: tin tool, stencil plate, chip holder included.
• Precision aperture alignment — matches KF1930 BGA pad pitch and footprint.
• Reusable across hundreds of reballing cycles with IPA cleaning between uses.

KF1930 Tin Tool Kit Specifications

FAQ — Whatsminer KF1930 Tin Tool Kit

Q: How wide is the actual cross-compatibility?
A: The same chip (and therefore the same tin tool kit) fits M32S, M32, M31S+, M31S, M31, M30S, M30, M3xS, M3x, and M20S hashboards. That's roughly 9-10 distinct Whatsminer SKUs covered by a single fixture.

Q: Is KF1930 the same as KF1921 or KF1922?
A: No — KF1921 / KF1922 fit older miners (M20S generation primarily). The chip silkscreen will read "KF1921", "KF1922", or "KF1930" depending on the production run. Match the silkscreen on your failed chip before ordering the matching kit.

Q: Standard rework profile?
A: Standard BGA reflow — preheat hashboard to 100-150°C, ramp to peak ~240-250°C, hold 30-60 seconds, controlled cool-down. Use flux paste and clean pads with IPA between heat-up and chip-place.

Q: What about hashboard variants on the same miner — do they all use KF1930?
A: Most M30-family hashboard revisions use KF1930, but Whatsminer has shipped occasional revisions with different chip variants. Always confirm by reading the actual chip silkscreen rather than relying on the miner model alone.

Q: Bulk pricing for repair shops?
A: Yes — email contact@lys-sz.com for volume pricing on KF1930 kits + matched chip stock (bulk orders of 1000+ chips often ship with a free stencil).
