Linear Issues Review


flux

Done. I focused the local reroute-prep rules on the hotspot cluster using the direct layout/review workflow: inspect with real-time project tools first, then apply targeted layout-rule changes rather than broad guesses
Updated local rules

Left unchanged Current review state
The hotspot prep is in place, but the board is still blocked mainly by existing unrouted/conflicting copper:
  • 96 airwires
  • 9 overlapping copper
  • 0 floating copper in the latest check
What this means
  • J2 now has friendlier local escape-routing rules for the 0.5 mm FFC area.
  • U5 keeps a slightly wider local trace rule than the buttons.
  • The button cluster KEY1 to KEY5 is now loosened consistently for future rerouting.
If you want, I can next:
  • review the exact nets around J2 and U5 that should get priority first
  • or tighten the backlight-related area around U5 separately from the button signals
Review priority nets
Separate U5 backlight
Check overlap hotspots
