The Elektor PCB Prototyper is a professional PCB routing machine designed for routing your own PCBs with isolation tracks down to 100 µm width, and drilling holes as small as 0.2 mm (.008’’) in diameter. Here at Elektor Labs—in the cellar to be accurate—we use our own PCB Prototyper machine when a PCB is needed in a hurry for building a prototype, or when we want to experiment with PCB shapes.
