We are discussing the importance of pre-hating components or the pcb in order to repair the board. I am interested in other peoples opinions on pre-heating.

Steve, We're not so sure that we've had enough of your rant. You say "I think it is the only place that looked pre-SMT for issues that everyone else just assumes is SMT. Any complete solution to SMT changeover times will look at pre-SMT as much as

Hi Chunks, Starting copper on outer layer with .0007 is 1/2 oz. copper foil. so if starting copper is .0007 and your Board house will plate an additional .0021 mils of copper. which will give you a finished copper weight of .0028 Mils or (2 oz.) Y

The board warp is a good place to look. Also: -Are you pre-rotating? -Are you using the largest nozzle possible? Most of the time this ends up being a component slip on the nozzle caused when the part is rotated if not doing pre-rotate, or slippa
