BM1366AL Hashboard ASIC chip for Antminer S19XP and S19XPhyd

BM1366AL Hashboard ASIC Chip – Antminer S19XP & S19XP Hydro Replacement

The BM1366AL ASIC chip is the hashing IC used on Antminer S19XP and S19XP Hydro hashboards. When a hashboard loses chips or reports chain errors, the BM1366AL is the first-line replacement — swapping the faulty chip restores lost hash power and returns the chain to full chip count. Every chip is selected for reliability across both air-cooled S19XP and water-cooled S19XP Hydro setups, so the same part number is reused across both SKUs on the repair bench.

Diagnosing BM1366AL Failures on S19XP / S19XP Hydro

Typical symptoms of BM1366AL failure: hashboard reports "x / y chips" short in the miner UI, single chain shows a cold spot on thermal camera, chain fails chip-count scan on a test fixture, or hashrate drops below nameplate by a discrete step matching one or more chips. Once localised, the faulty position can be reworked off and replaced. Pair the rework with a full chain scan and reflow of adjacent passives for best yield. A small buffer of BM1366AL stocks keeps S19XP fleets hashing without waiting for parts.

Rework Workflow Reminder

Preheat the hashboard to the recommended profile, desolder the failed BM1366AL with hot-air or IR rework, clean the pads, apply fresh paste through a matching BM1366AL stencil, align the new chip, reflow, then verify with a test fixture before returning the board to production. A chip-specific tin fixture avoids bridging and yields a near-100 % first-pass.
