I no longer have Altium license since when I moved to Kicad. If you are comfortable with KiCad design, I could replicate this design in Kicad, I would be happy to address the issues and recreate the design nicely to handle it. In KiCad there is JLCPCB Toolkit and will create the design in such a way that you can directly place the order to JLCPCB. I can share more details when contacted. Thanks

Hi Sergio T., Just last week I completed a similar task successfully, so I can get started on this without any ramp-up time. Can you confirm the intended JLPCB production stack-up (4 vs 6 layers), outer copper weight (2–3 oz), board thickness, and whether via-in-pad/back-drill are allowed? For the digital soft-start, are we ramping the MOSFET gates via a dedicated driver (part no.?) with current-sense feedback, or via ESP32 PWM/DAC through RC; and what is the target inrush profile and surge duration? Use a robust gate driver with Miller clamp and per-FET gate resistors; verify SOA with transient thermal modeling and size the ramp to keep each die within IDS–VDS limits during startup and surges. Harden measurement and returns: Kelvin-connect the shunt to an INA, star-tie PGND/DGND via a net-tie at the shunt return, add stitched copper fences in the power path, and enforce ESP32 antenna keepout to preserve WiFi. Action Plan: Phase 1 — DFM/DRC sweep; confirm JLPCB rules, stack-up/impedance, thermal/via strategy. Phase 2 — Power path refinements (trace/via/plane splits), implement soft-start and select driver/values. Phase 3 — ESP32 review (RF, decoupling, GPIO/sensors), add test points, bring-up checklist. Phase 4 — Signoff: annotated Altium commits, BOM with flagged substitutes, JLPCB FAB/ASSY outputs, panelization notes, impedance table. Phase 5 — Next-spin validation and brief report with soft-start waveform and ESP32 checks Best Regards, Sid

Hi, I can take your design from a solid prototype to a clean, production-ready board for JLPCB. Most of my recent projects are built around ESP32 (IoT control, high-current switching, and industrial monitoring), so your architecture fits perfectly with my experience. For your board, I’ll start by reviewing the 30A power path (trace width, copper balance, via stitching, thermal relief) and validate it under surge conditions. Then I’ll refine your soft-start approach (gate control + timing optimization) to reduce inrush and protect the MOSFETs. On the ESP32 side, I’ll run a full bring-up checklist: WiFi stability, GPIO mapping, and sensor interface validation to ensure reliable operation. Finally, I’ll prepare production-ready outputs: cleaned Altium files, validated BOM, and complete manufacturing package (Gerbers, PnP, assembly notes) ready for JLPCB. I’m available for live review sessions to explain decisions and close the remaining 20% efficiently. Let’s finalize this properly.

@Feriver
