There are some PCB designs where I need to have solder added to areas where high current is expected to flow. These areas on the PCB have the soldermask removed to allow for easy placement of additional solder. I add a region of solder to these areas in KiCAD. However, JLCPCB seems to ignore this and not add any solder to these areas. Is there a way to get JLCPCB to add solder to these specified areas of my PCB? Is there also a way to have JLCPCB add solder to the pads of non-populated components so that its easier when I go to add them myself?
