ASIC Diagnostic & Component-Level Repair Masterclass
Master oscilloscope waveform tracing, faulty ASIC chip isolation, LDO voltage regulator replacement, and hot-air SMD rework on commercial hashboards.
Who This Is For
Technicians, electronics hobbyists, and mining managers looking to stop shipping broken hashboards overseas for routine chip repairs.
Practical Knowledge & Bench Outcomes
- Use diagnostic test fixtures and multimeters to trace the 5 basic hashboard signals (CLK, RST, RX, TX, BO)
- Isolate blown domain voltage chips and replace low-dropout (LDO) regulators
- Execute high-precision hot air soldering and chip reballing with solder stencils
- Flash and recover corrupted EEPROM firmware chips on Antminer S19 and Whatsminer M30/M50 series
Curriculum & Session Schedule
Signal Path Tracing & Test Fixture Setup
Understanding how clock, reset, and telemetry signals pass through sequential ASIC domains.
Thermal Camera Fault Identification
Using FLIR thermal imaging to pinpoint shorted power domains and failing ceramic capacitors.
SMD Desoldering & Micro-Soldering Reballing
Temperature curve control, lead-free solder paste application, and stencil alignment under stereo magnification.
Bench Validation & EEPROM Verification
Powering boards on an isolated bench tester to verify full chip count and stable frequency response.
Scope & Equipment Exposure
In-depth component-level electronics troubleshooting on damaged hashboards using digital oscilloscopes, soldering stations, and thermal imaging cameras.
What Is Included
- Individual diagnostic test bench with Rigol digital oscilloscope, hot air station, and microscope
- Set of practice scrap hashboards and replacement ASIC chips for hands-on soldering
