One repeatable path
Start from the failure record, map the dependency chain, form testable hypotheses, and document what the evidence actually supports.
Free public review edition - July 2026
Systematic Debug
A Production Technician's Guide to Troubleshooting Electronics
This is a floor-oriented troubleshooting method for production PCB assemblies: receive the failure, preserve the evidence, identify the affected function, isolate the smallest defensible cause, and close the loop without pretending a guess is a root cause.
What makes it useful
Tools in context
DMM, oscilloscope, controlled power-up, thermal imaging, signal tracing, fixtures, ATE, rework, and known-good comparison.
Beyond the component swap
Traceability, escalation, quality integration, handoff, batch patterns, and case studies built around production constraints.
Safety and authority boundary
This book teaches diagnostic reasoning. It does not authorize electrical work, energized testing, rework, disposition, or deviation from controlled processes. Your training, qualification, employer procedures, product documentation, applicable law, and equipment ratings control the work. De-energize exposed hazardous circuits unless an approved exception and qualified-person procedure applies.
Free means accessible, not disposable
