Who I Work With

Technologies & Tools

Every design undergoes rigorous validation against IPC-2221, IPC-7351, and real-world DFM rules. My PCBs are optimized for high-yield manufacturing.

IPC Compliant
RoHS/REACH
CE/EMC Ready

My Engineering Process

A structured, battle-tested approach that minimizes risk and ensures manufacturing-ready results.

1

Requirements & Architecture

Define system specs, power, comms, environment, and create block diagrams.

2

Schematic Design

Professional schematics with proper net naming, power planning, and component selection.

3

PCB Layout

Precision routing with focus on signal/power integrity, thermal, EMI, and DFM.

4

Review & Optimization

Full validation: crosstalk, return paths, power delivery, thermal, DFM/DFA.

5

Deliverables

Gerber, ODB++, BOM, assembly drawings, test docs — ready for manufacturing.
