Antminer BM1398 Stencil Plate for S19 S19Pro T19 ASIC Chip Repair

BM1398 Stencil Plate – Antminer S19 / S19 Pro / T19 ASIC Chip Repair

This BM1398 stencil plate is a precision solder-paste stencil for reballing and replacing the BM1398AC, BM1398AD, BM1398BB and BM1485 ASIC chips used across Bitmain Antminer S19, S19 Pro and T19 hashboards. Manufactured from high-temperature steel with an anti-static coating, it delivers consistent paste deposits for high-yield chip rework. This is the stencil plate only — use it with your existing chip holder or reballing jig.

How to Use the BM1398 Stencil

Secure the BM1398 chip (or board area) in your reballing jig, align the stencil apertures to the BGA pad pattern using the corner marks, squeegee low-residue lead-free solder paste across the mesh, lift straight up, inspect the paste bricks under magnification, then reflow using the BM1398 thermal profile. The anti-static coating protects nearby passives during rework and the steel mesh stays flat across many reuse cycles.

Why BM1398 Stencils Matter for S19 / T19 Repair

The BM1398 is the main hashing ASIC across the S19 / S19 Pro / T19 generation. Chip failure is one of the most common root causes of lost hashrate on these boards — rework without a dedicated stencil risks solder bridging, cold joints and chain failures after reassembly. A chip-specific high-precision stencil pushes first-pass yield close to 100 %, which compounds across a farm-scale repair bench.
