The fine pitch of the IC leads requires accurate alignment of the stencil and the printed
circuit board. The stencil and printed circuit assembly should be aligned to within + 1 mil
prior to application of the solder paste.
No-clean flux is recommended since flux from underneath the thermal pad will be
difficult to clean if water-soluble flux is used.
