I am trying to cover the vias on my PCB using the solder mask however when I upload the PCB to a manufacturer's website the vias are not covered. I am using DesignSpark PCB software

There is a post in a forum from 2019 on how to cover vias however I cannot get it to work.

Do I expect the mask to fully cover the thermal vias or is the current configuration correct?

  • \$\begingroup\$ Check your gerber files with Gerbv. You should look into your solder mask layers. If the vias tented you would not see any holes on the solder masks. \$\endgroup\$

    \$\begingroup\$ The PCB manufacturer might supply such software. Or, have you looked at KiCad? \$\endgroup\$
