Antminer A113D Control Board Chip Tin Tool Kit | Anti-Static High-Temperature Composite Steel Stencil Plate + Chip Holder Set for S21 / T21 / S19j / S19j Pro Control Board Repair
The Antminer A113D Control Board Chip Tin Tool Kit is the complete reballing fixture for A113D control board chip replacement on Bitmain Antminer S21, T21, S19j, and S19j Pro control boards. Ships as a stencil plate + chip holder set — the two pieces needed to reposition the A113D chip cleanly during repair: the holder keeps the chip aligned with the board pads, the stencil deposits paste uniformly across the BGA pattern.
Crafted from high-temperature-resistant anti-static composite steel that prevents static charge buildup during chip replacement — A113D is ESD-sensitive and silent ESD damage is the #1 cause of failed control board swaps. Precision-cut steel mesh guarantees perfect alignment, the reinforced holder prevents slippage during reflow. Survives repeated soldering cycles up to 300°C / 572°F without warping or deformation — production-grade for repair shops servicing volume.
When to Use the A113D Tin Tool Kit
- Failed A113D control board chip replacement on Antminer S21, T21, S19j, or S19j Pro — fresh tinning before reflow.
- Control board refurbishment — volume A113D swaps across multiple boards benefit from a dedicated kit.
- Post-failure salvage workflow — fresh paste application around a salvaged A113D before reseating.
- Pre-deployment QC — chip-level rework on used control boards before redeployment.
- Repair shop standardisation — kit-driven workflow replaces freelance manual paste application.

FAQ — A113D Tin Tool Kit
Q: How is this different from the standalone A113D stencil plate?
A: The standalone stencil (P2-732) is just the laser-cut steel mesh plate. This kit includes both the stencil PLUS a reinforced chip holder — the holder physically positions the chip during reflow so it doesn't shift on the molten solder. For production-grade replacement work, the kit is the right choice; for occasional one-off repairs, the stencil-only is cheaper.
Q: Will it work for newer A113D variants on S21 XP / S21 Hydro?
A: Yes — the A113D footprint and pad pattern are consistent across the modern Antminer S21 generation. The kit works for S21, S21 Pro, S21 XP, S21+ Plus Hydro, T21, and the older S19j / S19j Pro control boards that share the same control IC.
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. Multi-kit discounts available for repair shops running A113D swaps at scale.
