I can wholeheartedly recommend designing your own PCBs as well. It's a lot of fun, and routing the tracks on the PCB is surprisingly calming.

- Athrunen 7y agoI am currently designing PCBs for my next post using EasyEDA, anything to pay attention to? I'm especially concerned about the track width and clearance and stuff. For 12V and I think a max of 8A I calculated 2mm width, 0.6mm clearance, 1.5mm via diameter and 0.75mm via drill diameter.
- StavrosK 7y agoMake sure you have your fab's clearances entered in, I had PCBs come shorted because my clearances were smaller than what the fab could deliver. 2mm sounds too narrow for 8A unless your length will be small, my calculator says 5mm+. Other than that, it's pretty foolproof, so enjoy the process!
- Gibbon1 7y agoYou can use this for calculating trace widths. I think 2mm is too narrow with 2oz copper and definitely too narrow with 1oz. https://www.4pcb.com/trace-width-calculator.html https://www.4pcb.com/trace-width-calculator.html Most PCB houses can handle 8mil (0.2mm) traces and clearance with no problems. Best thing way to handle vias in high current designs is to avoid them. Run the trace from point A to point B on the same layer. Second way is to use planes for distribution. Other things you can do. Make sure there isn't a thermal relief. Use multiple/arrays of vias.
