Milling – Eurocircuits

What we here mean with “milling” is a form of routing performed inside the PCB. This can be required to cut out the contour of a component, or to make room for any mechanical connection or for making slots, either NPTH or PTH in the board. The standard router is 2mm in diameter. Smaller diameters up to 0.5mm are...
