Could someone give me some advice for removing stubborn icu's? I'm trying to desolder U12 and U13 from a 500+ and they are proving so difficult.
I've a good solder sucker and it seems to have removed the solder from the underside of the chips. However when I look at the top side there still seems a lot of solder caked around the pins. Which probably explains why the chip still won't budge.
So my question is, how do you remove the solder which is applied to the pins on the top side of the board?
