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.
