Depending on the designers pad size, I generally go for 0.010" aperture with 0.010" spacing - stencil thickness 0.005". This combo with metal squeegees and the "usual suspects" of printer set up and placement details should you you hassle free.

Hello. I think, good stencil apertures is 80% from pad. And stencil thickness is 0.15mm - 0.20mm. I use 0.15mm thick stencil almost every pcb. Sorry my very bad english but i too learning. :)

Is there something I need to do to keep the Flash 5.0 download menu from popping up on my screen every few minutes? I have a higher version already loaded and do no want to download 5.0, but the constant prompting to do so is annoying.

nope, only placed 0.75mm pitch myself. I looked around some data sheets and did not find any 0.4mm.

Any aperture/stencil thickness suggestion to provide a rigid solder joint for 0.8mm pitch PBGA with 0.4mm ball diameter. The pad is based on IPC7095 and it is 0.3mm. Thank!
