I was wondering when I was trying to remove/replace SMT caps. As I am using a hot air rework, it heats up much more than just the solder joint. What I noticed is that the once normal looking board is browning up where I point the hot air.
The cap was dead and still dead, but is the stuff on the board that turned brown (must be some sort of organic?) or some conformal coating?
I still cant believe virtually *all* of the caps are bad and not just one or two...
