Prototype Boards Without the Wait
Isolation routing, engraving, drilling and cutting — the tooling and the setup that keep a milled PCB flat and accurate.

PCB Milling Tasks
PCB Engraving
Cut traces and pads directly into copper-clad board.
Isolation Routing
Separate traces with a V-bit and a controlled depth.
Hole Drilling
Through-holes and vias with micro drills.
Prototype PCB
One-off boards in hours instead of weeks.
Accuracy Tips
Getting a Flat, Accurate Board
Level the surface
FR4 is never perfectly flat. Surface leveling or an auto-leveling probe is the difference between cut traces and ruined boards.
Shallow, consistent depth
Isolation routing only needs to break through the copper. Deeper cuts widen the gap and lift burrs.
Zero runout
A micro end mill with runout snaps. Seat the tool properly and use a quality collet.
