I help clients design dense, high-speed, multilayer, and HDI PCBs with controlled interfaces, reliable return paths, and manufacturing-aware stackups.
This service is ideal for R&D teams, product companies, embedded and computing hardware teams. It is structured for commercially serious projects where reliability, performance, documentation, communication, and production readiness matter more than simply completing a drawing.
SERVICE SCOPE
✅ Layer-stack planning, material/thickness coordination, impedance strategy, and fabrication-capability alignment
✅ High-speed placement and routing for clocks, memory, USB, Ethernet, PCIe-related, MIPI-related, LVDS, high-speed serial, and processor interfaces as applicable
✅ Differential pairs, length matching, skew control, reference planes, return-path continuity, via transitions, and breakout planning
✅ Blind/buried vias, microvia strategy, via-in-pad considerations, dense BGA fanout, and compact placement
✅ Power integrity, decoupling, plane strategy, thermal spreading, EMI/EMC-conscious layout, and testability
✅ Manufacturing-output creation and final design review
WHAT YOU WILL RECEIVE
✅ Editable PCB source, stackup and impedance notes
✅ Complete fabrication/assembly outputs and 3D STEP model
✅ Critical-routing constraints and engineering documentation
ENGINEERING APPROACH
I normally begin by reviewing the product objective, development stage, available files, interfaces, expected quantities, enclosure constraints, operating environment, compliance targets, and the client’s main technical concern. For complex work, architecture review and finalization are completed before detailed circuit or PCB design begins.
High-speed PCB success depends on the interaction between stackup, placement, routing, reference structures, power distribution, packages, connectors, and manufacturing—not only trace-length matching.
RELEVANT EXPERIENCE
PCB experience includes up to 32 layers, controlled impedance, differential pairs, length matching, advanced stackups, blind/buried vias, and compact high-density designs.
Projects may be completed hourly or through clearly defined milestones. Components, fabrication, assembly, shipping, laboratory certification, paid software/services, and other third-party costs are separate unless specifically included.
To receive an accurate scope, please share the product requirements, existing schematic or PCB files, block diagram, datasheets, mechanical information, expected deliverables, target schedule, and any known technical issues.
