Hi to all,

We are testing stencil-printing process for adhesive dispensing in bottom
side for 0603 components.
We found that there are some adhesive dots that are touching the pads.
We found that the maximum distance that the dot penetrates the pad is
approximately 0.0025".
Is there any standard that defines if it is acceptable to have a small
quantity of adhesive over the pads?
Is there any thumb rule that indicates the size of the stencil aperture.
We have a 0.028" clearance between the pads, and an average dot size of
0.0225".

Thanks,




Alejandro Becerra
