I was told by my MFG ENGR that Castle - ation comes from the shape along the
top of the wall in the living place of the Knights and Lords of England,
Whales, Spain etc. I was asked to make a 'castellated' footprint for a DPAK
transistor so it would create a solder fillet around the top of the mounting
tab...

Does anyone else know more about this term and whence it came?

Hi Franklin!
It's a type of soldering termination on a part, instead of being leaded,
it's
lead-less. Usually a half-round plated area on the sides of a part...
Go to my pictures and you can see what one looks like (with bubbly plating
and all...)
