Advanced Hashboard Component Diagnostic Lab
Precision component-level troubleshooting, oscilloscope testing, and LDO voltage regulator repair.
Format & Location
2-Day Advanced Lab Session (14 Hours) • Logic Bridge Hub Diagnostic Lab, 67 Main Street, Dawson VIC 3858
Tuition & Pricing Basis
$1,650 AUD per person (includes micro-probing consumables and test fixtures)
Program Overview & Real-World Result
An advanced hands-on lab dedicated to oscilloscope signal tracing, finding open circuit traces, testing level shifters, and replacing failed buck converters on ASIC hashboards.
Expected Practical Competency: Attain proficiency in using digital test fixtures, identifying faulty 1.8V / 0.8V LDO regulators, diagnosing temperature sensor communication breakdown, and performing solder rework on surface-mount passive components.
Delivered By
Senior electronics repair engineers with 10+ years in micro-electronics diagnostics.
Target Audience
Electronics technicians, repair shop operators, and self-maintainers who have completed our foundation masterclass.
Curriculum & Technical Scope
- Schematic reading for Antminer 17/19 series and Whatsminer hashboard architectures
- Signal line tracing: Clock (CLK), Reset (RST), Command (CMD), Data (TX/RX), and Return (RI)
- Buck regulator circuit diagnosis and MOSFET gate driver troubleshooting
- Using specialized single-board test fixtures and serial log debugging
Step-by-Step Delivery Process
1. Schematic & Architecture Deconstruction
Walking through domain-voltage series chains and signal transmission paths.
2. Signal Probing on Live Test Fixtures
Injecting test signals and following the oscilloscope trace to pinpoint the defective chip.
3. Component Replacement & SMD Rework
Hot air desoldering and replacement of faulty capacitors, diodes, and LDO regulators.
4. Full-Chain Stress Testing
Running the board through a 60-minute automated test sequence to confirm stability.
Included in Program
- Individual workstation with Rigol digital storage oscilloscope and precision micro-tweezers
- Practice hashboard units with simulated hardware faults for live diagnostics
- Lab safety gear, fume extractor stations, and solder consumables
Program Exclusions
- High-volume commercial contract repair services (this is hands-on diagnostic instruction)
Preparation & Requirements
Prerequisite: Completion of our foundation masterclass or demonstrable electronics soldering experience.
Capacity Constraints
Strict limit of 4 participants per session.
