    Oops! Screwed The Pooch

    My progress on modding a donor radio to retain the DIC with a Navi HU was going well until I broke a small part off the DIC board. You can see the tiny part below the board in this pic. Timing sucks to get a replacement because I have trip due 15 May next week.



    I've heard of a product called Silver Conductive Epoxy Adhesive. It claims to be an electronic grade epoxy with good electrical and thermal conductivities. Anyone tried anything similar with good results? If its doable, not even sure I can even get something like this locally.

    I may end up having to remove and cut the DIC board from my original 6 disc radio. If I do, and want to get a replacement later on, will I need a replacement DIC board thatís actually from another 6 Disc radio?

    Well here are some picís of the modded parts that I took just before I broke the part off the DIC board.



    If you look closely at the MB below, you can see the two Aluminum "L" Brackets that I made to attach it to the sides of the case.


    Got diagnosed with an upper respiratory infection this morning, so off to the pharmacy to pick up medication. Real Bummer!

    I see the capacitor sitting on the towel just below the daughter board. But I don't see where it came from on the DB. Have you tried it out to see if that cap actually did something that you need for this mod? I know this, depending on how far you cut up. You might of disabled the right side lights for board that contains the dial and what not. There's a thread here some where that explains what needs to be done to get it back. I wish that I saved it, but it was before a time that I knew how. lol. So if those lights don't work, don't be alarmed. I've been living without those lights for the last 2 or 3 years.

    That just sucks, get this better before you lose patience on the radio though.

    I used that compound to reattach a rear window antenna lead. It worked fine, though the lead was a standard size male flat connector (considerably larger)

    Best I can tell is the capacitor was in the location by the red arrow I just drew on the pic.


    I haven't tried it yet, not feeling too energetic today. I should have stopped working on it yesterday afternoon before attempting to cut a bit more off the ends of the board, since it was still a little too long when I dry fitted the new HU. Hopefully, I’ll feel much better with more energy this Saturday and can install to see if the DIC operates or what functions might be missing without that capacitor. I can live temporarily with the lights not working, if that’s the case for the length cut.

    Yea, I definitely want to get this respiratory problem cleared up. Hopefully, I'll feel much better with even better concentration with two days of meds in my system.

    Thanks. So far, I haven't been able to find anyone locally the stocks the product. Few places say 2-3 days for orders.

    Re: Oops! Screwed The Pooch

    For Crying Out Loud, Wes.

    You broke that little can capacitor off, its so simple to fix.

    If the legs on the can are still long enough (hold it in place on the board where it broke off and match the broken legs to the pieces sticking out of the solder) you can just buy a soldering pencil and if you are temor-free, hold the can in place and touch the tip of the pencil to the solder on the board until it changes from a solid to a liquid and push a leg into the solder blow your breath on it and pull the pencil away. It will turn back into a solid. Then do the other leg. Its that simple.

    Any electronics shop or Boy Scout with a merit badge can do it.

    That capacitor new comes with an inch worth of leg, thay aren't part of the capacitor's operation, just what's inside the can is. It stores electricity.

    KOT and DuMaurier have it.

    Umm X, the cap is directional. It's a DC circuit sir. Besides, it has that black mark on the top indicating negative.

    Wes, don't be scared though. Even the board indicates the direction. So just match it up with the others. Where the black mark is as compared to the board.

    OUCH!

    You could also buy a new cap. at the same value for like 15 cents and re-solder it in if the original is screwed. You don't even have to push it thru the board you can tack solder it to the broken legs that are still in there. Any radio or TV repair shop could also do it for like 5 bucks. (forget the glue crap....it won't work right)

    It's surface mount cap. Little legs are used, they aren't even chopped off when done soldering.

    Yes it's a electrolytic capacitor. (Polarized with the black indicating positive.) Can't read the value though. Totally fixable but it's going to be fun re-soldering
    it when there are barely any legs left on it! (it may work out) I would try and desolder the two silver pads first so you can get clean holes to re-mount either the
    original cap or a replacement one. Or I would use a new cap with legs long enough to tack it to the pads.
    On the bright side this is the best componet to break off if you had to have it happen...ever try and re-solder one of those surface mount resistors....oh man

    Re: Oops! Screwed The Pooch

    I think I made my point. Solder it back on. If you have to buy a new one you'll get jabbed for something that's $8 /100 or whatever but its no big deal.

    Hey guys, thanks for all the good info and suggestions. Kind of thought that cap might be directional. Downside is, I'm just not comfortable, as a first timer, trying to solder that tiny capacitor or a replacement back on the board. So that would be a desperate attempt for me.

    Will trying calling some electronics and computer repair shops to see if they will repair it. If that fails, then look for a replacement capacitor at the Shack and then go for it. I can also just remove and mod my original radio's DIC board. Just hate go that route.

    Wes, its an easy firsttimer. Caps are hard to ruin. Buy a soldering pen with a fine tip. Just hold the tip on the solder that's already there until it melts and stick the correct leg into the solder. Then do the other one. You can buy some solder to practice with before you work on the board. Its really so simple to do. Low wattage soldering iron, warmed up and as simple as dipping a pen in ink.

    Why would you want to dip a pen in ink? I thought pens came with their own ink, don't they?

    Re: Oops! Screwed The Pooch

    If someone charges you more than 5 bucks for this repair, they're ripping you off. I do a lot of electronics work, and it'd take longer for the iron to heat up than it would to fix it.

    I know you don't know me, but if you can't find someone local, send me a PM, I'll do it for the cost of return shipping. I modded my DIC as well, changed all the LEDs to make my DIC and A/C display blue instead of that nasty orange.
