just 'ponderin'... 1k lb mobos...approx. 600 boards?
.5 ounce p/heat sink X 2 p/board... 600 ounces=37.5lb of AU @ .50 p/lb..$16.87
mmmm.. if yer docked .50 lb ?? (just a guestimate) on 1k lbs... $500 .25 p/lb $250..
...I guess it depends on how much they would dock you, and what yer time is worth. As is usual with breaking down scrap ...
I would think I could go through a couple hundred boards p/hour.. $75-$100 p/hr ???
