PCB EXPERT
When a PCB fails, the visible symptom is rarely the real fault. A blown fuse, no output, low voltage, overheating MOSFET, or a dead board usually starts deeper in the power path.

About this Gig
When a PCB suddenly stops working, overheats, resets randomly, or fails after assembly, the real issue is usually deeper than a single bad part.
I help identify why your board failed, which component is causing it, and what must be corrected before the next build.
This gig is focused on PCB component failure analysis, fault isolation, and root cause debugging for prototype boards, custom electronics, assembled PCBs, and production problem boards.
Problems I can help diagnose
PCB not powering on
Short circuit on power rail
Burnt resistor, capacitor, MOSFET, IC, regulator
Intermittent failure or unstable output
Board heating abnormally
Prototype works once then fails
Batch production failures
Unknown faulty SMD component
Open circuit or solder-related failure
Wrong component selection causing failure
What I do
Review schematic, PCB layout, BOM, test notes, scope readings, or board photos
Trace likely failure path
Identify suspected faulty component or failure region
Determine probable root cause:
thermal overstress
voltage/current overstress
wrong footprint
assembly defect
polarity issue
layout-induced failure
poor decoupling
grounding/power integrity issue

FAQ
What do you need to analyze my PCB failure?
Send any of these if available: schematic, PCB layout, Gerber, BOM, board photos, voltage readings, thermal photos, oscilloscope captures, or a short explanation of what failed.
Can you identify the exact failed component?
Often yes, especially when enough design files or measurements are available. In some cases I can narrow it down to the most probable failure region or suspect components.
Do you repair physical boards?
No physical shipping is required. This gig focuses on engineering diagnosis, failure analysis, and root cause identification.
Can you help if the PCB worked before and suddenly failed?
Yes. That is one of the most common cases thermal stress, electrical overstress, aging parts, assembly defects, or layout-related instability.
Can you help before I send the board for manufacturing again?
Yes. Many clients use this to avoid repeating the same fault in the next prototype or production batch.
Can you analyze production batch failures?
Yes. If several boards fail with similar symptoms, I can help trace likely common-cause failure mechanisms.
