    Default Electronic wizards please help !

    I decided i needed to know what got busted on my CD30 after my fishing brolly hit it at speed.

    Once opened and stripped down, i find that the printed circuit board has fractured and broken the copper circuit, hense only one side of the stereo is working !

    What i need to know from you electronics guys is can it be repaired or is it totally fect ?

    Couple of pics of it below for you to study.


    Have consideration for the deaf, if you're gunna fart, make it smell !

    Im an IT Consultant by trade, and iI'd say you goosed there. Though its possible to reconnect the bridges etc, it's also cracked through the points where there is solder.

    So they would have to be resoldered etc.
    May be worth seeing if you can get the PCB off of fleebay

    Depends if it's a multi layer board. If it is...it's fit for the bin. If it isn't, you could do a repair but it looks like a fairly big job andthere is room fir errors. I could have done it in my avionic days, but not now. I don't have the tools now.

    As above a pretty straight forward repair providing you have the right tools and a steady hand and assuming few components have been cracked, obviously worth a bash as you have nothing to loose.

    It's probably repairable and is almost certainly a dual-sided board rather than multi-layer; but it will take a lot of effort, a good soldering iron with a suitable tip, lots of suitably tinned wire and a good deal of patience. You'll also have to create test points and thoroughly test it with a multimeter. Lastly, there's always the chance that one or more discrete components have been damaged already, and irreparably, if voltage has been applied *after* the physical damage was caused.

    As the last poster stated, I'm inclined to think its just a double sided pcb, and tracks looks quite well spaced out which makes the job much easier, from the pics I would say it is repairable. If your soldering skills are not too good then best to get someone else in to do it. Tracks should'nt pose too much of a problem to repair, though it depends if any of the smt components have suffered any fractures where the crack has passed underneath or close to them.

    I bet Kman could have that up and running for you mate. Other than that buy another broke CD30 and swap parts.

    Hi Phil , I could get it working....only problem is that its a stress fracture and when you go to use the buttons there's a chance it may go faulty again. if you want to post me the board I'll do some magic with it , but remember I cant garauntee it will work for ever.

    Might be possible to reinforce the damaged bits after repair with small bits of fibreglass mat and epoxy, have done that with some pcb's at work before.
