IC Chips and Electronic Components for ASIC Miner Hashboard, Control Board, and PSU Repair

The IC chips, MOSFETs, capacitors, regulators and discrete components on a hashboard or control board are the failure points behind most "dead miner" scenarios that aren't a bad cable or a dead fan. When a single ASIC chip on a hashboard burns, a MOSFET on the PSU controller fails, or a capacitor leaks on a control board, the miner shows symptoms that point everywhere except the actual cause. This collection covers the full spectrum of electronic components we stock for ASIC miner repair — hashboard ASIC chips (Bitmain BM1397, BM1398, BM1362, BM1366, BM1368, BM1370, BM1373CC ; Whatsminer / MicroBT chips for M30 / M50 / M60 series ; Avalon A3200-3204 ; Iceriver UP9650AQR1), PSU repair MOSFETs and controllers (NCP1399AC, IPW60R037P7, SRC60R090B, G47N60EF), temperature sensors, voltage regulators, capacitors, and the matched components used in chip-level repair work across Antminer, Whatsminer, Avalon, Iceriver, and Innosilicon hardware.

When you need component-level parts (and when you don't)

Component-level repair makes economic sense when the miner is current-generation and the alternative is replacing a whole hashboard or PSU. Common scenarios :

• Single ASIC chip burned on a hashboard — most modern Antminer / Whatsminer hashboards have 60-120 chips in series. A single dead chip drops the chain. Replacing the bad chip with the matching part (BM1398, BM1362, BM1366, BM1368, etc.) and remapping the EEPROM saves a $300-500 hashboard.
• MOSFET shorted on PSU primary — IPW60R037P7 or G47N60EF MOSFETs on Innosilicon G1240 and Bitmain APW PSUs can short under sustained high load. $3-8 part replaces $200+ PSU.
• Half-bridge controller failure on PSU — NCP1399AC controllers on resonant PSU topologies fail closed and the PSU stops switching. Component swap is straightforward for repair shops with SMT skills.
• Capacitor leak or temperature sensor drift on control board — 47uF 50V SMD electrolytics, PA800V477M0E G477 polymer capacitors, 25TQC33M tantalums, LM75A, TMP102, S75 temperature sensors — sub-dollar parts that fix mysteries.

Why source IC chips and components from LYS Shenzhen

Three reasons component-level repair shops and farm engineering teams source from us :

• Sourcing depth — Shenzhen is the global hub for ASIC chip aftermarket. We have direct supply relationships with channels that handle both genuine and tested-equivalent components, including chips that are officially EOL but still required for hashboard repair on older Antminer S17 / S9 and Whatsminer M20 / M21 generations.
• Lot-tested for hashboard reflow — ASIC chips destined for hashboard repair are batch-tested before shipping. Defective chips that pass visual inspection but fail under reflow are the biggest hidden cost in repair operations. We filter them out at the source.
• Bulk pricing for repair shops — at $0.06 to $9 per component, IC chip repair only makes economic sense at scale. Quote-based volume pricing reflects that. Worldwide shipping with DDP option for US and EU customers — small parts ship fast.

Frequently asked questions

Are these ASIC chips original Bitmain / MicroBT or aftermarket ?
ASIC chips are original — BM1397, BM1398, BM1362, BM1366, BM1368, BM1370 and the equivalent MicroBT and Canaan series are sourced from channels that handle authentic factory chips. We don't carry counterfeit or remarked ASIC chips. Discrete components (capacitors, MOSFETs, regulators) are sourced from major electronic component channels and clearly labeled.

What's the difference between a "genuine" ASIC chip and a "pull" or "recovered" chip ?
Pull chips are recovered from used hashboards. They cost less but carry higher failure rates because they've already been through reflow once and may have suffered thermal stress. Where we stock pulls, they're clearly labeled. Most of our hashboard ASIC inventory is new genuine.

Do I need an EEPROM remapping tool after replacing a single chip on a hashboard ?
Yes for current-generation Antminer (S19 / S21) and Whatsminer (M30+) hashboards — the firmware tracks bad chip locations and you need to remap after physical replacement. Our universal EEPROM programming cable covers Antminer and Whatsminer hashboards.

I have a control board issue but I'm not sure if it's a chip, a capacitor, or a power regulator — can you help diagnose ?
Send a description of the symptoms (no boot, no IP, kernel panic, restart loop, etc.) plus a clear photo of the board top and bottom. Our team will narrow down the most likely failure point and the candidate replacement part. We don't charge for diagnostic input.

Can I order chips and components for older Antminer S9 or Whatsminer M20 series ?
Yes. Legacy chip inventory includes parts for S9 (BM1387), S17 (BM1397), older Avalon and Innosilicon generations. Some are stocked, others are sourced on request. Send your model and required part number for a quote.
