BM2110AA ASIC Chip Tin Tool for Antminer KA3 Hashboard Repair

BM2110AA ASIC Chip Tin Tool | High-Temperature Fixture for Antminer KA3 Hashboard Chip Replacement

The BM2110AA chip tin tool is a chip-level rework fixture for the BM2110AA ASIC used on Antminer KA3 hashboards (Kaspa kHeavyHash). Built from high-temperature-resistant composite that withstands repeated 220–250°C reflow cycles, with a steel mesh featuring precise hole positions matching the BM2110AA pad array 1:1.

Critical for Antminer KA3 repair: the BM2110AA package is dense and unforgiving to freehand iron-tinning. A misaligned solder deposit causes bridging across pads on first power-up and kills the chain instantly. The stencil deposits an even paste layer across every pad in one pass, with built-in anti-static protection to prevent charge-buildup damage that shows up days later as silent hash drops.

When You Need This Tin Tool

• Replacing a failed BM2110AA ASIC chip after KA3 chain diagnostics flag a missing chip in a specific position.
• Re-tinning chip pads after lifting a dead chip — even paste deposit for the next reflow.
• Recovering working chips from a scrapped KA3 hashboard for reuse.
• Bench throughput — speed and consistency over freehand soldering on the dense BM2110AA pad array.

FAQ — BM2110AA Tin Tool

Q: How do I identify which BM2110AA chip needs replacing on a KA3 hashboard?
A: A chain tester scans each chip serially and reports the position of the first missing or non-responding chip. Use a hashboard tester to localise the failure before lifting any chip.

Q: Hot air station profile for BM2110AA reflow?
A: Bottom-side preheat 130–150°C, top-side hot air 320°C following the solder paste manufacturer's reflow profile. Preheat the entire aluminum substrate before applying top-side heat — KA3 hashboards pull heat away fast and skipping preheat causes uneven reflow on the chip being installed.

Q: Reuse the stencil — how many cycles?
A: Composite material is heat-stable across many cycles. Wipe with IPA after every reflow — clogged apertures from dried paste cause starved joints on the next chip, not heat fatigue. Stencil end-of-life is usually paste contamination, not material wear.

Q: Bulk pricing for KA3 repair benches?
