ExpressPCB order you need stencil for.
Each selection is one physical stencil.
Home Base apertures are used to control solder balling and tomb-stoning of chip components. Trapezoidal Apertures are created by distorting the beam on the laser, creating a draft in the aperture wall.
Fiducials are alignment marks consisting of a 1 mm circle surrounded by a 2 mm clearance. If your screen printer is equipped with a vision system, fiducials half cut (into the thickness) of the stencil will allow for the printer to automatically align the board with the stencil. If you are manually aligning the stencil with the board, you could either fully cut the fiducials through the stencil or just us any surface mount pad to align the stencil.
Kit includes Solder Paste, Pick & Place Tool, Temperature Marker (331 degrees to 379 degrees), 1 pair of gloves, 2 alcohol wipes.
