User’s Manual 59
It is recommended that you allow for an “exclusion zone” of 0.04" (1 mm) around the
RCM3400 in all directions when the RCM3400 is incorporated into an assembly that
includes other printed circuit boards. This “exclusion zone” that you keep free of other
components and boards will allow for sufficient air flow, and will help to minimize any
electrical or electromagnetic interference between adjacent boards. An “exclusion zone”
of 0.08" (2 mm) is recommended below the RCM3400 when the RCM3400 is plugged
into another assembly using the shortest connectors for headers J1 and J2. Figure A-2
shows this “exclusion zone.”
