Mario,

We are about to start using a 3mm x 3mm QFN. The pad size is .2mm x .25mm with a thermal pad. We are currently using NC-SMQ92J with mesh size -325/+500. Should we change to the -400/+635 mesh. This product will also have QFP’s/BGA’s/Transformers/Inductors, etc.

We currently use Laser cut w/Electropolish stencils at 5mils.

Thanks for your help.

Regards,
Joe
