Refine STM32 PCB for Production
Budget: $10 – $30 USD
I already have the complete KiCad project — schematic and routed PCB — for a compact STM32-based board. The core functionality is proven, but the layout still needs a professional polish before I commit to an industrial run at JLCPCB.
Here is what I expect:
• Clean, manufacturable routing: tighten up trace widths, via placement, and layer transitions so power paths are short and low-impedance.
• Robust ground strategy: a continuous ground plane with stitched vias that controls return currents and keeps EMI in check.
• Signal-integrity fixes: length matching where required, impedance-controlled nets, and reduced stub lengths to eliminate the poor signal integrity I’m currently seeing.
• Component upgrades: review and, if necessary, re-footprint the USB Type-C connector, key power components, and critical signal-line parts to boost durability and assembly yield.
• Thermal management: address the local hot spots already flagged in the prototype by improving copper pours and adding thermal relief where needed.
• Full JLCPCB readiness: final Gerbers, CPL file, and BOM formatted for their assembly line, plus any design-for-manufacture tweaks to stay inside their standard capabilities.
Deliverables are the updated schematic, PCB files, fabrication outputs (Gerber, drill, pick-and-place), and a concise design report summarising all improvements.
If you work in KiCad and have taken STM32 boards through production before, your input will let me move straight to the next hardware spin with confidence.
