FAQ — B20 ASIC Chip Tin Tool
Q: B20 vs BM1489 tin stencil — which to choose? A: Both target Antminer L7 hashboards but match different chip families on different board revisions. Verify the chip silk marking on your L7 board (B20 or BM1489) before ordering. Wrong family won't have matching footprint.
Q: Do I need B20 replacement chips separately? A: Yes — this is the tin tool kit only. For complete L7 hashboard repair, you'll also need (1) replacement B20 chips and (2) thermal grease for re-pasting after new chip installation.
Q: Stencil + chip holder vs stencil alone? A: The chip holder fixture is what makes this kit professional-grade — it secures the chip in correct alignment during reflow, eliminating positioning errors that cause solder bridges or cold joints. Bench-only stencils without holder are cheaper but produce more rework defects.
Q: Bulk pricing for L7 refurb shops? A: Yes — email contact@lys-sz.com with your monthly L7 hashboard rework volume for tier pricing.
