Electrical tolerance
Tolerance for scoring cut (V-cut)
If you have scoring on the outline of the printed circuit board, the following tolerances apply:
substance like an ink tolerances Mechanical and is applied in a thin layer similar to varnish on the entire surface of the printed circuit less on the soldering pads and it also has a role of antioxidation of the copper traces. Being a substance with a high degree of
circuits, the inductance and capacitance of the printed circuit board conductors become significant, usually unwanted, circuit elements; rather, they can be used as part of the circuit design, as in distributed element filters, antennas, and fuses, Mechanical tolerances avoiding the need for additional separate components. High Density Interconnect (HDI) PCBs have traces and/or insulation less
better adaptation is required. When producing the printed circuit with controlled impedance, tolerances Mechanical the impedance will be controlled by acting on the dimensions of the tracks and the distance between them, i.e. the insulation. For a multilayer printed circuit with a specific stack-up, it must be taken into account that the internal tracks
