    Hey guys, I'm currently in the process of recapping my model 1 Sega CD. Unfortunately, the contact pad for C44 came off and I have no clue what to do in order to fix this (if there is any).

    Anyone so kind as to tell me what my options are?

    Like any pad repair. Run a link to where it was going.

    The picture should be pretty obvious where you need to scrape and solder.

    Also, it looks like you iron is way too hot. Not that the pad got loose.

    It's the track on the top right? I've never had to repair a broken pad before, do I scrape that little hole or should I pick another location?

    I have my iron at around 350-400 degrees celcius.

    This is the trace, you can see at the top of where the solder pad this is where it would connect.

    You can scrape right near where the pad was a solder a wire or something

    Thanks mate. I'll get back to work then.

    Edit: I've scaped a bit off, applied some flux but can't get anything to attach to that surface. Am I doing something wrong?

    Ok it seems to work now. Just not very durable it seems. But hey, at least I learned something. Thanks again!

    Alright, so everything is still working fine (including your BIOS). I'll finish this tomorrow by adding a tiny bit of hot glue to this and some other loose pads. Right now I'm really happy I didn't demolish the system AND that I learned how to do this in the future (and that my iron was too hot).

    What flux and solder are you using?

    At a guess, I'd say no flux and lead free. Hence why you overcooked it and burnt out the pad trying to get the solder to wick. At a minimum get a tub of rosin and some rosin core leaded solder for this kind of work. You'll also want bottle of Isopropyl alcohol and an old toothbrush to clean the flux off after.

    A properly soldered joint will never need hot glue to keep it together.

    Thanks for the tips. The pad got off after I finished soldering because I was too uncareful. I'm using rosin core solder, but have no idea if it's lead free or not. I'm always using isopropyl alcohol 96% with a cotton swab to clean after I desolder. I sometimes use addition flux before I start with the new sodder. I don't always clean up with alcohol after I'm done though, should I just get used to always doing so?

    I've lowered the temperature of my iron to 300 degrees Celsius when working on things like this now.
