Advanced protoboard layout with 1.27mm pitch for smd parts

Advanced protoboard layout with 1.27mm pitch for smd parts

Main Features

  • Plated through holes in standard 2.54mm raster like on traditional protoboard
  • Pads for smd parts in 1.27mm raster in between
  • SOIC parts can directly be used without adapters
  • SMD pads are not contacted to the other side:
    • Different tracks can either cross each other or connect
    • No wires to solder in like on non-plated-through protoboard
  • Allows for much more dense layout

You can build your own protoboard for SMD component using the production file on
