Mask Fiducial Problem | 25 January, 2017

Our Stencil Mask Fiducial vanishes from black color to light where our Screenprint machine unable to detect fiducial during batch teaching (auto set-up alignment). Does anybody here encounter the same problem? I am searching for a dark marker or any material that cannot easily disappear after frequency of cleaning so that we can rework the mask fiducial by simply applying with the marker. thank you

Hi,

I used black marker before and it will works for a while, but it is not a permanent solution. Ask stencil house what kind of material and process they use to apply the black material. I think this operation might be done manually after the stencil is cut(just like painting it with a brush).
