PCB Net Routing Issues

flux

0:26

Thought for a moment

You’re right to be frustrated. At this point, I can still help diagnose nets, verify schematic connectivity, clean stale traces, run DRC, and export once clean — but I currently cannot draw arbitrary manual PCB copper traces/vias from this chat session unless Flux exposes that manual routing action to the AI session.
To let me finish it automatically, Flux would need to add AI-accessible support for:
  • drawing a trace between two pads on a named net
  • choosing layer, width, and path points
  • placing vias tied to a net
  • routing differential pairs with spacing/length constraints
  • editing/deleting individual trace segments reliably
You do not need to add this yourself unless you are developing Flux. As a user, the practical path is:
  1. Manually route the listed nets in the PCB editor using the Trace/Route tool.
  2. Route in this order:
    • FSYNC → GND
    • EP pads → GND vias/pour
    • LOUT+ → speaker connector pin 1
    • RTS/CTS/RXD → TXS0104E ↔ SIM7600G
    • USB D+/D− last, carefully as a short matched pair
  3. After each net, run DRC and confirm that airwire disappears.
  4. Once you finish, ask me to “run DRC and export Gerbers,” and I can validate and generate the manufacturing files if clean.
For USB D+/D− specifically: keep the two traces parallel, same length, close together, avoid vias, don’t cross gaps in the ground plane, and keep them away from LTE/GPS/RF and switching regulator areas.
