Take one step or the whole development path. Each engagement ends with something you can check: a document, a log, the captures.
Turn what the product must do into requirements you can test, then choose the architecture and the key parts that meet them.
Schematic and PCB layout, or an independent review of yours, checked for signal integrity, power, thermals and DFM before you commit to fab.
First power-on, validation against the requirements, and root cause on anything that fails, intermittent faults included.
Make a working prototype repeatable: test plans, documentation and the fixes that make it manufacturable.
Schematic, layout, BOM, the symptom. Whatever exists.
A written scope with what is in, what is out and the price.
Findings and captures shared as they happen, not saved for the end.
A controlled document you can file, with everything needed to repeat the result.
Schematic and layout reviewed before fab, findings in writing.
Your boards on the bench from first power-on to working, with the log and captures.
Hardware help on call through design, validation and production.
