AlphaMetal WS1208

Do you have some experience with solder paste WS1208. What is the "best" conditions for printing process? I mean type of stencil, apertures, squeegee.

Do you have original data sheet of this solder paste? - life time, working time on the stencil, shelf life, storage conditions.

We have problem with quality of the print - how to setup large process window.

Thanks for inputs and opinions.
