Inspection of pads

Hello,

I am experiencing issues with one of my PCB suppliers. Specifically, I am having trouble with solder shorts occurring on a SOIC8 component, and always in the same pads. Upon inspection with a microscope, I discovered that three of the pads are 3 mils shorter than the other ones and the stencil is leaving solder on the solder mask instead of the pads. To prevent this problem from happening in the future, I am interested in finding an optical inspection machine that can measure all the pads accurately. If you can help me with this, I would greatly appreciate it.

Thank you.

Thanks
