i used Proteus 8 to design my PCB. recently i received my fabricated PCBs and notice that the MOSFET's drain SMT pad is somehow covered with the soldermask, which it shouldnt.
i have asked the PCB house and they mentioned that unfortunately based on the given Gerbers that the MOSFET's drain pad is not visible.
tried some modifications and yet the PCB house still unable to see the pad in the Yellow circle.
