burnt my balls off
Hello engineers I’m a newbie with a simple question for you. I am trying to learn how to micro-solder and was practicing on an i-phone 7 logic board, attempting to remove the audio i.c. Probably too complicated for training, but after i finally got the i.c. off I noticed several of the balls on what I guess would be the base were missing. They looked silver as opposed to the copper colored ones on the i.c. I tried to apply solder thinking the solder would be attracted to the spot where it should go but no luck
