I joined the Pad Lifter Club

[Mk.558]

I would clean the board first.

For me, I put the pad back where it belonged and glued it in as recommended. Well, predicatably, the glue did not hold for squat. Solder paste is not a bad idea.

For my second motherboard, I went to RadioShack and got 10 47uF electrolytic radials. It's very difficult to make a hot soldering job with my low level of skill. Short leads give me plenty of room, I will then glue the capaciters and leads for support. While not as good as tantalums, at least I won't have to worry about that for awhile.

Not quite ready to join this club as yet, though I'm resigned to the notion that I will be become a member soon! :

My lifted pad was actually TORN off and I found the Cap/Pad (along with a couple other components) inside the anti-static envelope. It/they must have been knocked off while the card was in storage or during shipment.

Thanks for all the great info in this thread gang! :b&w:

I have another SE/30 mobo that has some bad caps (no audio) and the most wonderful smell I adore and know since long ago: the smell of burning circuit boards. There was some liquidy stuff near C2 when the thing froze after about two minutes of being on.

So yes, I might also join that club too...

Count me in. Lifted my first on my Portable today. That will teach me to try to pull caps the quick way. There was a good amount of goo that attacked it underneath. The solder doesnt flow so well with that crap all over it. I was able to clean it up, repair the traces, put on the new capacitor and get it to boot again.

Needless to say the rest got cut off, can pulled and legs desoldered. It's the only real way to deal with the crusty old ones. Now to finish the rest on my Classic II board.

While we are here, most discuss Simasimac as the primary indicating of bad caps. However I still get Simiasimac when booting -- I heard I should clean my RAM and ROM contacts. Any other suggestions?

Also, in the ... ugh... stress of moving I broke the retaining springy plastic clips that hold in the ROM chip on my spare motherboard, so now it will go in but not "click".

Any way to fix that? I was thinking if I had to use it the ugly way would be to use a capped spring (so it won't conduct electricity) on the battery holder to "push" the ROM module in place.

I ended up jerry-rigging the ROM SIMM in place with a couple small diameter toothpicks (preferably square than round) and a lot of Scotch tape. It works okay until the ROM SIMM decides to slightly shift position or the tape loses some of its adhesive ability, then you are back where you started. I was tempted at one point to just solder the damn thing in place. } But even that was too scary, especially when you consider how many contacts you have to solder small wires to and swapping out the ROM SIMM socket for the more "permanent" configuration.

You could try and also experiment with hot glue to see if it will provide a more secure method, yet still allow you to remove the card, should you need to. Just a thought. :
