BM2110AA ASIC Chip Stencil Plate | Laser-Cut High-Temperature Resistant Tinning Tool for Antminer KA3 Hashboard ASIC Chip Replacement and Reballing
The BM2110AA Chip Stencil Plate is the dedicated tinning fixture for BM2110AA ASIC chip replacement on Antminer KA3 hashboards — the Bitmain Kadena (Kaspa-class) miner that uses the BM2110AA hashing chip. Drop-in tool for repair shops servicing KA3 fleets: deposits solder paste uniformly across the BM2110AA pad pattern with no bridges, no cold joints, no manual paste application that wastes 30 minutes per chip.
Crafted with high-temperature resistant materials that survive repeated reflow cycles without expansion or deformation. Laser-cut to precise dimensions matching the BM2110AA OEM footprint, eliminating misalignment during the tin implantation process. Repair shops running KA3 chip swaps at volume benefit from the consistency of a dedicated stencil — manual paste application varies between technicians and leads to rework that costs more than the stencil itself.
When to Use the BM2110AA Stencil Plate
- Failed BM2110AA chip replacement on an Antminer KA3 hashboard — fresh tinning before reflow.
- KA3 fleet refurbishment — volume chip swaps across multiple boards benefit from a dedicated stencil.
- Post-failure salvage workflow — re-tinning surviving BM2110AA chips that came off a board during a fault event.
- Pre-deployment QC — clean tinning on chips installed during refurbishment.
- Repair shop standardisation — stencil-driven workflow replaces freelance manual paste application for consistent quality.

FAQ — BM2110AA Stencil Plate
Q: Is the Antminer KA3 still economically viable for mining in 2026?
A: KA3 economics depend on Kadena (KDA) price and difficulty trajectory. Operators with low-cost power and existing KA3 fleets continue to run them; new deployments are rare in 2026. Chip-level repair is a cost-effective path to keep existing fleets producing vs writing off boards.
Q: Why use a dedicated BM2110AA stencil vs a generic one?
A: Generic stencils don't match the BM2110AA's specific aperture pattern. Result: solder bridges between pads, cold joints, or wasted paste. A dedicated stencil for the exact chip footprint gives consistent, repeatable tinning across the chip and across multiple chips in volume work.
Q: What solder paste should I use?
A: Standard lead-free solder paste (Sn96.5/Ag3/Cu0.5 or equivalent) sized for fine-pitch BGA reflow. Match your hot-air rework station's reflow profile.
Q: Bulk pricing for repair shops?
A: Yes — email contact@lys-sz.com with your monthly volume. KA3 fleet operators get multi-stencil discounts.
