2.1 Recommended Metal
Solder Stencil Aperture
It is recommended that only
0.152 mm (0.006 inches) or
0.127 mm (0.005 inches) thick
stencil be used for solder paste
printing. This is to ensure
adequate printed solder paste
volume and no shorting. The
following combination of metal
stencil aperture and metal stencil
thickness should be used:

3.0 Pick and Place
Misalignment Tolerance and
Product Self-Alignment after
Solder Reflow
If the printed solder paste volume
is adequate,
the unit will self-
align
in the X-direction after
solder reflow. Units should be
properly reflowed in IR Hot Air
convection oven using the
recommended reflow profile. The
direction of board travel does not
matter.
