My worst nightmare has come true

[MikMac]

In the summer of 1993 I purchased a Macintosh Color Classic. I maxed out the memory, added the FPU, and added VRAM. I used this system for a long time. It has been sitting unused for the last 10 years. A few weeks ago I opened it to discover all of the caps were leaking. I had one try at recapping my Macintosh Classic, so I felt I'd give this one a try.

In the process of desoldering the caps I pulled up 2 pads. I have no idea if or how I can fix this. I think it's destroyed.





What can I do? Can it be repaired? I'm not very skilled with soldering. Maybe I can arrange an outsource agreement for someone to repair this for me.

i think you will be just fine, i am sure someone on here knows where those pads go, you can just run some wire to the proper spot,
i personally do not have a schematic for that board.

If nostalgic reasons make you wish to keep it stock, repairs ought to be good experience for you. Otherwise, there are excellent MoBo upgrade options available, from a simple swap to G3 level complexity, if your board can't be saved.

Did you keep the pads? All you need to do is super glue the pads back onto the board and with an exacto knife probe around the ends to find the trace it was connected to (you will have to lightly scratch off the green coating to find the broken trace). Then just solder bridge the broken trace together and you are good to go soldering a new capacitor on top.

Sorry to hear about this. There are quite a number of folks with the knowledge (as evidenced by the previous responses) to help - and quite a few with the actual skills.

I know thetechknight has a number of videos on his YouTube channel in which he recaps and otherwise repairs Classic compact Mac logic boards. I obviously can't speak for him, but I'd bet his repair rates are fair and reasonable, if you feel you can't complete the repair yourself.

Yeah, I ended up lifting about 4 pads trying to do my Classic II. (Which I later read online was notorious for weak pads.) I've managed to put three of them in a bag, and lost the forth. When I have the funds I plan to have someone else to (hopefully) fix the pads and put on the new caps.

It was a real bummer for me, cause I was planning to learn THINK Pascal on it. (I can always use my PowerBook or something, but the Classic II was my first Mac.)
Also looks like my LCIII needs new caps, cause it ain't booting up anymore.

I see right where both pads go. Look at the picture, if you use a magnifying lense, itll be easier to see that where the traces are that go right up to the pad.

Just follow the trace and make your repair with a piece of 30guage wire.

BTW, I like the monster picture. love it. Also , you see the via right where the pad would have gone just above the pad. For example. The second cap, you see the trace twisted from where the pad lifted off, and at the same junction , you could see where the trace ran to the via.

LC III's are pretty easy to recap, you have much more room to work with. I revived one of my dead LC III boards (sound died with a whine, never rebooted again) with a simple cap job (still have that board on the shelf since I stuck a 68040 board inside).

Sorry, couldn't help it.....



It's all I could think off since I read the title.
