For the surface mount versions of the ULQ, use the Recommended SMT Pad
Layout illustration as a starting point to locate pads to mount the converter.
This diagram is for the pads on the mating printed circuit board—it is not
the dimensions of the lead terminals on the converter. Note: the pads are
slightly larger than the lead terminals to accomodate solder wetting and
meniscus. Also, your particular application may require some deviation from
this diagram.
