Maybe something like this could work?

I am optimizing a stencil opening for BGA with 0.4mm pitch and pad diameter of 0.2mm. Can anyone advice of stencil thickness and stencil opening I can use in order to have a good paste release. Thanks for all your answers.

Yes, 0.25x0.25 square could work @0.1 thickness, use nano-coating or electroform stencil for better solder paste release.

Use a type 5 solder for maximum paste release.

Please check what is the actual pitch size. I found some of the designer use 15.7 mil pitch and no accumulate ie 15.7, 15.7 and 15.8...... Also, I recommended the pad width should be 10 - 11 mil for 0.4mm pitch. You can open the 10 - 10.5 mil aper

I will have to process a PQFP 128 with a pitch of 0.4 mm. Given that the width of its leads are about 0.13-0.23 mm, i dread the worst when printing the solder paste. So, i would like to know if some people have yet test this type of fine pitch, what

check the archives (keyword="16 mil pitch") and also consider 45 degree pattern printing. Regards.
