PCB Net Routing Issues
Thought for 7 sec
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:
- Manually route the listed nets in the PCB editor using the Trace/Route tool.
- 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
- After each net, run DRC and confirm that airwire disappears.
- 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.
