Trace width?

Hey,

nice work! Whats the max. resaonable trace width to route between the inner pads?

Assuming you're getting JLCPCB (or a manufacturer with similar capabilities to make it), here's what I've found.

JLCPCB Capabilities

  • NPTH to Track: 0.2mm
  • Min Trace Width: 0.1mm

(NPTH = Non-Plated Through Hole, aka Mechanical Hole)

KiCAD Settings

  • Set "Copper to Hole Clearance" to 0.2mm
  • Use wide traces for the outer pads (e.g., 0.25mm), especially for power.
  • Use 0.15mm traces for passing between the mechanical holes.

One more detail to note is that it may be possible to route trace(s) to the inner pads from the edge-side of the PCB. Perhaps the bigger question is here "how close does this footprint need to be to the edge of the PCB"? Will report back in a month when my clip arrives.
