Share your interfaces, target data rates, layer count, and fab house, I will deliver a stable, production-ready high-speed pcb you can manufacture with confidence.
FAQ
Do you manufacture or ship physical PCBs?
No. I deliver fabrication-ready design files (Gerber, BOM, SCH/BRD, STEP). You can manufacture and assemble with any PCB fab/assembly house.
What interfaces do you support for high-speed routing?
HDMI, PCIe, USB/USB-C, MIPI DSI/CSI, Ethernet, and SDIO. I handle differential pairs, length matching, and impedance control.
Do you provide controlled-impedance stackup and fab notes?
Yes. Standard and Premium include stackup guidance and fabrication notes to meet your target impedance with your chosen fab.
Can you review or fix an existing high-speed PCB?
Yes. I can audit routing, return paths, pair matching, and constraints, then provide optimized layout files and recommendations.
What file formats will I receive?
Gerber + drill files, SCH + BRD source files, BOM (CSV/XLSX), and optional 3D STEP for enclosure fit.
What layers and complexity can you handle?
From 4 to 8 layers, including complex boards with HDMI/PCIe/DDR/MIPI interfaces.
Do you include signal integrity simulations?
I provide SI-aware routing and impedance control. Full SI simulations can be added on request if needed.
What do you need from me to get started?
Your interfaces, target data rates, layer count, fab house (if chosen), constraints, and any existing schematic or reference design.
Can you help with prototype bring-up and fab handoff?
Yes. I provide DFM notes, stackup guidance, and prototyping advice to ensure smooth manufacturing.
