BM1766AA Antminer ASIC Chip Tin Planting Stencil | Replaceable Steel Mesh for Quick and Reliable BM1766AA Chip Tinning
The BM1766AA Tin Planting Stencil is the laser-cut steel mesh for solder-paste deposition during BM1766AA ASIC chip replacement. Used in conjunction with the matching tin tool fixture — the stencil aligns precisely over the BM1766AA chip footprint, the mesh apertures deposit a uniform paste layer on every pad, and the technician reflows the chip onto the hashboard without uneven welds or short circuits.
The stencil is a consumable — over enough reflow cycles the tin steel mesh wears out, leading to uneven tin application and leakage. Replacing the worn stencil restores precision and dramatically improves the chip-welding success rate. Crafted from environmentally friendly materials with high-temperature resistance, anti-expansion properties, and no deformation under sustained reflow duty. Precise hole positions ensure accurate tin plating on every cycle.
When to Use the BM1766AA Tin Planting Stencil
- BM1766AA chip replacement on Antminer hashboards — primary use case for restoring failed chip positions.
- Worn stencil replacement — original mesh has accumulated wear, uneven paste deposition is degrading repair yield.
- 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 replacement on aging Antminer hashboards with marginal BM1766AA chains.

FAQ — BM1766AA Tin Planting Stencil
Q: Does this stencil come with the tin tool holder?
A: No — this listing is the stencil only. The matching BM1766AA tin tool / chip holder ships under a separate listing. For the complete reballing setup buy both.
Q: How many reflow cycles before I need to replace the stencil?
A: Depends on solder paste type, cleaning rigour, and reflow temperature profile. Stencils typically handle 100–500+ cycles before aperture geometry drifts enough to affect paste deposition uniformly. Inspect under magnification regularly.
Q: Is the steel mesh compatible with all standard solder pastes?
A: Yes — the laser-cut steel mesh is compatible with both leaded and lead-free pastes. Match the paste choice to the chip's reflow temperature spec.
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 tin tools.
