Hi, I am a new engineer and I will be doing some of the ordering of stencils in the future. I am inquiring about the possibility of making the stencil fiducials through hole. We are forever coloring in the fid with a black sharpie marker so that the camera would pick the fid up. Would making this a through hole be possible and if so I was wondering how any you felt about its effectiveness. Would this work and eliminate the problem or do you see any draw backs?
