SE FDHD battery leakage + capacitor explosion (I guess it's my turn now!)

Posted by: JRL on 2019-12-19 05:19:44 So I picked up a non-working SE FDHD for free last Sunday as part of a larger free score. I anticipated that it would have the exploding Maxell syndrome and it indeed did. The actual acid damage doesn't seem to be terrible (it did disintegrate one pin on the scsi chip, I have a replacement on the way) but the cap directly to the next exploded dramatically as well. Haven't had time to do a detailed wash just yet but the cap leakage seems to have left white stains on the board that aren't coming off with a IPA/toothbrush scrub - would anybody have any ideas on what I could use? This FDHD is in pretty nice condition overall so I would like to fix this board eventually. (First picture is what the board looked like when I pulled it out) (2nd is after the quick scrub) -J

Posted by: JRL on 2019-12-19 13:56:17 Thanks guys! And thank you LaPorte, I read through it earlier! Waiting on a new desoldering gun to come in before I go further.  I still am having trouble getting some of the white capacitor residue off of the board though, some of it scrapes off with a small flathead but i don't want to be too harsh on the board (already scrubbed at it with IPA a lot). Has anybody dealt with a similar thing? I think if it's safe I'll try some acetone next.
