Component-Level Repair
Board inspection, fault isolation, schematic tracing, soldering, component replacement, and post-repair testing.
About
Electronics Test, Troubleshooting, and PCB Development
My background includes component-level repair, industrial electronics testing, schematic analysis, soldering, and PCB development.
I am Kweisi John. I came into electronics through the practical side: fixing phones and laptops, learning to solder, reading schematics, repairing power supplies and other boards, and testing industrial electronics down to the PCB level.
That background changed how I look at design. A board is not finished because the schematic is clean or the layout looks good. Someone still has to power it safely, reach the right node, understand the failure, and prove the result.
My current work combines repair and test experience with original PCB and embedded-hardware projects. I show the decisions, uncertainties, and evidence state without pretending a simulated result is a physical measurement.
Industrial Hardware Test
Functional testing and troubleshooting of industrial motor drives, tram controllers, power electronics, and PCB assemblies.
Schematic Analysis
Power paths, signal paths, component behavior, expected measurements, and fault-isolation decisions.
PCB Development
Requirements, component selection, schematic capture, PCB layout, test access, bring-up planning, and project documentation.
Where to go next
Hardware projects
Original boards and design work with explicit evidence states.
Services
Board diagnostics and repair, PCB assembly and rework, hardware testing, and documentation.
Technical writing
Circuit analysis, design decisions, testing, and diagnostic notes.
Connect
Collaboration, project inquiries, and relevant technical partnerships.
