For the high voltage tracks ground and 450V, I use very thick tracks in order to withstand enough power (>4mm width). And then, the rest of the tracks for signal and 12V, are using just 1 mm tracks. And that’s it, the PCB is ready, but this time with 10 coils and it has a size of 47 cm long by 5 cm.

I generate the GERBERs and go to PCBWAY.com. Insert the PCB size and click quote now button. Here I select the red color for the soldermask. I add to cart and on the next page I upload the GERBERs generated with Altium. Submit the order and receive the PCBs in just a few days. They look awesome. I know that the black finish is my favorite but I also like the red color, it looks great, right? So, if you want to try my project, download the GERBERs for free.
