Whatsminer KF1922 Stencil Plate | CNC Laser-Cut Solder-Paste Tool for M20 / M20S / M21 / M21S ASIC Chip Replacement
The Whatsminer KF1922 Stencil Plate is a CNC laser-cut precision stencil for KF1922 ASIC chip replacement on Whatsminer M20 / M20S / M21 / M21S hashboards. Aligns precisely over the KF1922 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 bridge shorts and dry joints that come from uneven manual paste application.
Built with ±0.01mm hole tolerance via CNC laser cutting, on high-grade steel alloy with a burr-free finish. The high-temperature resistance lets the stencil survive repeated reflow cycles without dimensional drift. Designed specifically for the M20 / M20S / M21 / M21S generation — the aperture pattern matches the KF1922 chip layout used across this miner generation. Stencil plate only — matching chip holder ships under a separate listing.
When to Use the KF1922 Stencil Plate
- KF1922 chip replacement on Whatsminer M20 / M21 hashboards — primary use case for restoring failed chip positions.
- Repair-bench volume work — repeatable paste deposition across multiple boards per shift.
- Post-rework reflow — fresh paste layer before re-seating a salvaged or reworked chip.
- Fleet refurbishment — chip-level rework on aging M20 / M21 hashboards before redeployment.
- Repair shop standardisation — fixture-driven workflow replaces freelance manual paste application.

FAQ — KF1922 Stencil Plate
Q: Does the stencil come with the chip holder?
A: No — this listing is the stencil only. The matching chip holder is sold separately. For the complete reballing setup buy both.
Q: Will this stencil also cover the M30 / M50 generations?
A: No — the KF1922 aperture pattern is specific to the M20 / M21 generation. For M30 / M30S use the KF1930 stencil; for M50 / M50S use the KF1968 or KF1978E stencils depending on hashboard revision.
Q: How many reflow cycles before I need to replace the stencil?
A: With proper cleaning between uses and flat storage, a high-grade steel stencil typically handles 200-500+ cycles before aperture geometry drifts enough to affect paste deposition uniformly. Inspect regularly under magnification.
Q: Bulk pricing for repair shops?
A: Yes — email contact@lys-sz.com with your monthly volume and we'll send tier pricing on stencils and matching chip holders.
