Additionally, is there an equation that I could use to calculate clearance depending on voltage? Aug 11, 2017 · Dust is another factor since particulates that collect on the surface of the PCB can form a track over time, shortening the distance between conductors. Henry Gault, my mentor at the time. See the IEC 62368-1 table for the PCB creepage and clearance base factors. Otherwise, you must multiply the different altitude correction factors by the obtained clearances. However, it is important to consider several factors such as the dielectric breakdown strength of the PCB material and the required clearance based on safety regulations. Jul 16, 2024 · How much current a PCB trace can carry limits your design, so you can use this tool to verify if everything is going to be okay without having to return to the drawing board in the future. 5mm.
