hello guys

i have a problem with 5 pcb way, they arrived last week, when I fed the pcb with an external source I noticed that the mosfet 2940 was very hot, I noticed that it had a short to ground on capacitors c37, c7 and c9, basically all capacitors around the ci STM32, the line of 3.3v shorted too, I removed the ci and the short disappeared, I believe it was something wrong mounted, I don't want to believe that the ci's placed on this board are really shorted, did anyone have the same problem?

Can you give some more information about the pcb when it was shorted. Did you replace any parts or just remove and are they working now?

 

PCBWay will send you pictures of components before soldering, can you check back to those and see if anything was mounted the wrong way. If it was they would have gone ahead and done every pcb the same.

 

Thanks
