 IR recommends that the larger Power or Land
 When using SMD pads, the underlying copper
Area pads are Solder Mask Defined (SMD.)
This allows the underlying Copper traces to be as
large as possible, which helps in terms of current
carrying capability and device cooling capability.
traces should be at least 0.05mm larger (on each
edge) than the Solder Mask window, in order to
accommodate any layer to layer misalignment.
(i.e. 0.1mm in X & Y.)

 Ensure that the solder resist in‐between the
the edge of the device, IR recommends that these
are Non Solder Mask Defined or Copper Defined.
Window should be larger than the Copper Pad
by at least 0.025mm on each edge, (i.e. 0.05mm
in X&Y,) in order to accommodate any layer to
layer misalignment.
smaller signal lead areas are at least 0.15mm
wide, due to the high x/y aspect ratio of the
solder mask strip.
