Splet28. nov. 2024 · Hole to Line spacing not working Fredda over 2 years ago Constraints: Constraints are enabled: But some other constraint seems to be active: The pink color is the hole and the kind of shaded part in the middle is the pad, which will be removed by the drill. So it's a NPTH. Any ideas why I can route as close as 0.15 mm to the hole and not 0.3 mm? SpletThe values should be based on a “Right First Time Design for Manufacturing” principle and functionality of the PCB. Track widths and isolation gaps are important as they define the current load, impedance and electronic signal integrity for a PCB. Therefore, the track widths chosen depend upon the actual functionality of the PCB.
