Re: what is pastemask ??

Paste Mask

A stainless steel template in a tightened frame, with holes corresponding to landpatterns on the bare board that are either cut, punched, or drilled with a laser. The solder stencil is used at the beginning of the circuit assembly process where it is placed on top of a bare board, solder paste is pushed through the holes, then the stencil is lifted away. This leaves small solder paste deposits on the bare board, onto which components are placed.

Solder paste output don't need to be included with the PCB manufacturer data set. But many designers find it reasonable to send the complete gerber data to all involved parties.
