IPC-SM-782 Figure 3-8 specifies that the minimum land to land spacing
between two different SMD IC type components is 0.050"(1.25mm).  Section
3.6.1.4 seems to indicate that the spacing between any two component lands
could be as small as 0.020" (0.05mm).  I would like to use the smaller of
the two since my board is very crowded.  What do you believe the real
clearance is?
