Whatsminer KF1968 Tinning Stencil Plate | ASIC Chip Solder-Paste Tool for M50 / M50S Hashboard Repair
The Whatsminer KF1968 Stencil Plate is the laser-cut steel mesh for professional KF1968 ASIC chip replacement on M50 / M50S hashboards. Aligns precisely over the KF1968 chip footprint so solder paste deposits uniformly across every pad — the cleanest way to prep a board for chip reflow and the surest way to avoid the short circuits that come from uneven manual application.
Crafted from high-grade stainless steel with a laser-etched mesh accurate to ±0.03mm. The 300°C (572°F) heat-resistant design resists warping during repeated reflow cycles, keeping aperture geometry consistent across hundreds of repair jobs. Cuts tinning time roughly in half compared to manual paste application. Stencil plate only — matching chip holder sold separately.
When to Use the KF1968 Stencil Plate
- KF1968 chip replacement on Whatsminer M50 / M50S hashboards — primary use case, restores hashrate after a chip failure.
- Repair-bench volume work — repeatable paste deposition across dozens of boards per shift without redoing the alignment.
- Post-rework reflow — fresh paste layer before re-seating a reworked or salvaged chip.
- Fleet refurbishment — preventive chip replacement on aging M50 / M50S units with marginal chains.
- Repair shop bench standardisation — replace freelance manual paste application with a stencil-driven workflow for consistent quality.

FAQ — KF1968 Stencil Plate
Q: Does the stencil come with the chip holder?
A: No — this listing is the stencil plate only. The matching chip holder is sold separately. For the complete reballing kit (stencil + holder + accessories) see the KF1968 Tin Tool Kit.
Q: Will this stencil also cover the KF1968E variant?
A: The KF1968 and KF1968E share the same chip footprint on M50 / M50S hashboards — same stencil aperture pattern. Confirm against your specific board revision if in doubt.
Q: How long does one stencil last?
A: Properly cleaned between uses and stored flat, a stainless steel stencil typically handles 200–500+ reflow cycles before aperture geometry drifts enough to affect paste deposition. Replacement frequency depends on solder paste type and cleaning rigour.
Q: Bulk pricing for repair shops?
A: Yes — email contact@lys-sz.com with your monthly throughput and we'll send tier pricing on stencils, chip holders, and the complete tin tool kit.
