HELLO THERE,

I will design a 4 layer PCB engineered for controlled impedance, high speed signal integrity, and reliable manufacturability. My design approach focuses on stack up engineering, return current continuity, reference-plane integrity, differential pair routing, and noise reduction to support demanding digital and mixed-signal applications.


What I Provide:

  • 4 layer PCB layout and optimized layer stack-up
  • Controlled impedance routing for single ended and differential signals
  • High speed routing for USB, Ethernet, LVDS, and other supported interfaces
  • Signal integrity optimization and return path management
  • Power and ground plane design with decoupling optimization
  • Design rule checks (DRC) and electrical rule checks (ERC)
  • Gerber, drill files, BOM, pick and place, and fabrication outputs


Why Choose Me?

  • Impedance aware stack up and trace geometry
  • Signal integrity focused routing strategy
  • Clean power distribution and grounding
  • Organized design files and technical communication


Ready to move your PCB from concept to fabrication? Send your schematic, interface requirements, and board constraints so I can define the appropriate stack up and routing strategy for your project.
