Whatsminer KF1980E Tin Tool Kit – Stencil + Magnetic Base + Scraper – M60 / M60S / M61

Whatsminer KF1980E Chip Tin Reballing Tool Kit – Laser Stencil, Magnetic Base & Solder Scraper for M60 / M60S / M61 Hashboard Repair

The KF1980E tin planting fixture is a dedicated BGA reballing kit engineered for the Whatsminer KF1980E ASIC chip — the hashrate chip fitted to Whatsminer M60, M60S and M61 hashboards. The complete set includes a magnetic positioning base, a KF1980E-specific femtosecond-laser tin planting stencil, and a stainless steel solder scraper. The integrated positioning design allows even beginners to plant solder in a single pass, eliminating the chronic bench-side failures of manual reballing: misalignment, uneven solder ball size, short circuits, solder bridging, and chip detachment from pads. It is a standard repair consumable for mining-repair workshops and data-centre maintenance teams running M60-class fleets.

Kit Contents — 3-Piece Precision Tin Tool

Every kit ships as a complete matched set: (1) KF1980E laser tin planting stencil for the BGA pad pattern, (2) magnetic anodised aluminium positioning base to hold the chip and stencil in exact alignment through the reflow, and (3) stainless steel solder scraper to deposit paste evenly across the stencil. The three components are designed together — swapping in a mismatched stencil, base or scraper defeats the alignment guarantee that makes the kit worth using.

KF1980E Precision Laser Tin Planting Stencil

• Material: imported 304 high-elasticity stainless steel — non-magnetic, corrosion-resistant, retains dimensional stability under repeated heat cycles.
• Manufacturing process: fully automated femtosecond-laser drilling, aperture positions matched 1:1 to the KF1980E BGA pad layout, with chamfered edges to prevent solder bridging on release.
• High-temperature resistance: withstands repeated 380 °C hot-air-gun heating without warping, deformation or cracking — the stencil survives long-term production use rather than degrading after a handful of jobs.
• Process optimisation: smooth, burr-free inner walls give clean solder-paste release and uniformly rounded solder balls — the failure modes of bridging, insufficient solder and empty spots all disappear.
• Durability: engineered for thousands of soldering operations, stays unclogged after routine cleaning, and does not rust in a normal workshop environment.

Magnetic Aluminium Alloy Positioning Soldering Base

• Substrate: aerospace-grade hard-anodised aluminium alloy — anti-static, so the base cannot inject an ESD event into the delicate KF1980E die during handling.
• Strong magnetic adsorption: built-in hidden magnets automatically adhere and lock the steel stencil, preventing displacement during hot-air-gun heating — no need to keep it pressed with tweezers.
• Precise positioning: the mould's inner groove replicates the KF1980E chip's shape exactly, auto-centring the chip with zero misalignment.
• Thermal stability: no expansion or deformation under prolonged hot-air heating, so positioning accuracy stays constant across long production runs.
• Anti-slip base: silicone pad on the bottom prevents the base from sliding on the repair bench when hot.

Stainless Steel Solder Scraper

• One-piece moulded stainless steel with a smooth blade for even pressure and consistent solder-paste application.
• Anti-slip handle reduces hand fatigue over extended reworking sessions.
• Correctly sized for the small-area BGA footprint of the KF1980E, so paste is not wasted onto the surrounding base.

When to Use This Tin Tool Kit

Reach for the KF1980E kit whenever an M60 / M60S / M61 hashboard has a failed or degraded KF1980E chip — specifically chip oxidation, cold solder joints, short circuits or burnout flagged by the kernel scan or a test fixture. The kit handles both the desoldering / resoldering of an old chip on its original pads and the pre-soldering (reballing) of a fresh replacement chip before it goes down onto the board. Both operations are the difference between a board that comes back to full hash rate cleanly and one that comes back with a marginal joint that will fail again a few weeks later.

Application Workflow

Place the KF1980E chip into the base's inner groove — the moulded pocket auto-centres it. Position the laser stencil over the chip; the hidden magnets in the base lock it in place without pressure from tweezers. Apply lead-free solder paste along the top edge of the stencil and pull the stainless steel scraper across in one steady motion — the chamfered apertures release the paste cleanly onto the BGA pads. Heat the assembly with a hot-air gun at ≤380 °C until the paste reflows into uniformly rounded solder balls. Lift the stencil straight up (do not slide), remove the chip, and inspect the reballed pattern under magnification before placing the chip on the hashboard.

Important Notes — Compatibility & Care

Chip compatibility is strict. This kit is dedicated to the KF1980E ASIC chip only — it is not compatible with other Whatsminer chips such as the KF1978E or KF1968. Attempting to use it on a different chip footprint defeats the whole benefit of a 1:1 stencil and typically damages the fresh chip.

Care for the stencil. The stencil is a delicate thin component: do not bend it forcefully when unpacking. Clean with a lead-free circuit-board cleaner; do not scrub with a hard-bristled brush. Stored flat between jobs, the stencil will hold aperture geometry across thousands of cycles.
