Barry,

I have seen this term used once.  It refers to an aluminum plate which
covers the PWB.  There are holes in the plate for component leads.
These openings look similar to the steps of a ladder, hence the name.
The body of the component rests against the aluminum plate and the heat
from the component is conducted to the plate then away from the
component by conduction within the heat ladder.  This can be used to
cool a CCA by pure conduction, or can simply increase the surface area
for convection cooling if there is airflow over the CCA.  This is one
way to deal with cooling, but is quite expensive.
