Collection: Chip Tin Tool for Hash Board ASIC Chips - Easy Installation & Reliable Protection

Chip Tin Tools, Stencils, and Thermal Paste Molds for Hashboard ASIC Chip Repair

Hashboard repair work has become an industry of its own — repair shops processing batches of failed Antminer S19, Whatsminer M30, and Avalon hashboards depend on precision tin tools, stencils, and thermal paste molds to reflow ASIC chips, apply solder paste in exact alignment, and deposit thermal compound at OEM tolerance. This collection covers every chip tin tool, stencil, and mold we stock for Antminer (BM1387, BM1393, BM1396, BM1397, BM1398, BM1362, BM1366, BM1368, S19XP, S21XP, S21+ Hydro, S19j Pro+ Hydro), Whatsminer (KF1930 series M30 series stencils), Avalon, and other ASIC miner brands. Built for repair shops that process boards at volume, with form-fitted tooling for each chip generation.

When you need a stencil, a mold, or a tin tool

Each tool category covers a specific step in hashboard rework :

• Tin stencils (steel mesh) — apply solder paste to the chip pads on the hashboard before placing the new ASIC chip. Holes are laser-cut to OEM pad dimensions for each chip family (BM1398, BM1362, BM1366, BM1368, A3200 series, etc.). Critical for clean reflow without bridges or starved joints.
• Tin fixture stencils (plastic positioning) — hold the chip in exact alignment over the stencil during paste deposition, preventing the chip from sliding off-pad during placement. Universal fixture stencil covers multiple Bitmain BM series, dedicated fixtures for each Antminer generation.
• Thermal paste molds / heat sink alignment plates — deposit thermal compound at OEM thickness across all chips on a hashboard in one operation. Antminer S19XP, S21+ Hydro, S21XP Hydro and S19j Pro+ Hydro have dedicated molds for each generation.
• Large-chip hashboard tin tools — for hashboards using larger ASIC packages (S19j Pro L), where standard small-chip stencils don't apply.

• Antminer hydro stencils — S21XP hydro silicone grease stencil (stainless steel, 1:1 OEM hole positions, burr-free edges), S21+ Hydro thermal grease stencil, S19j Pro+ Hydro large-chip thermal paste mold.
• Whatsminer M-series stencils — KF1930 stencil plate for M30 series hashboards, M50 / M60 dedicated stencils where available.
• Large-chip Antminer S19j Pro L tools — large chip hashboard tin tool for thermal paste application on S19j Pro L variant.

Why source chip tin tools from LYS Shenzhen

Three reasons hashboard repair shops standardise on our chip tin tooling :

• OEM-precision tolerances — every steel mesh stencil is laser-cut to OEM pad dimensions for the target chip family. Burr-free edges, 1:1 hole positions, no off-spec stretches that cause solder bridges or starved joints during reflow. We don't sell loose-tolerance "universal" stencils that ruin boards.
• Multi-variant inventory — Antminer S21XP and S21+ Hydro both have hashboard variants (A3HB70501 / A3HB70503) with different chip layouts. We stock stencils for each variant, not just the most common. Select the correct version for your hashboard P/N.
• Bulk pricing for repair shops — at $4-$88 per stencil or mold, individual rework operations are inexpensive but repair shops process hundreds per month. Quote-based volume pricing reflects scale. Worldwide shipping with DDP option for US and EU customers — small tooling ships fast.

Frequently asked questions

How do I know which hashboard variant (A3HB70501 vs A3HB70503) I have ?
The hashboard part number is printed on the silkscreen of the board itself, typically near the connector edge. Read the P/N off the failed hashboard and order the matching stencil version. If the P/N is illegible, send a photo of the chip layout and our team will match the variant.

What's the difference between a stencil and a fixture stencil ?
A stencil is the steel mesh with cut holes that defines where solder paste lands on the board. A fixture stencil is a plastic positioning frame that holds the chip aligned over the stencil during paste deposition. Many repair operations use both : the steel stencil for paste deposition, the plastic fixture for chip placement. Both are stocked in this collection.

Can I reuse a steel stencil across multiple boards ?
Yes — steel mesh stencils are reusable for hundreds of operations if cleaned properly after each use (isopropyl alcohol + ultrasonic cleaning for residual paste). Plastic fixture stencils have a shorter lifespan due to wear at the alignment edges, typically 50-100 operations before paste leakage becomes an issue.

I'm a single-miner home operator — is component-level stencil work worth it ?
For a single miner, no — sending the hashboard to a repair shop or replacing the miner is typically more economical. Stencil-based rework makes economic sense at repair-shop volume (10+ boards / month) where the per-board cost drops well below repair-shop service rates.
