    So... is there a localish soldering expert?

    Got a machine with a circuit board where one of the capacitor's has broken off in transit, the company that makes it is based in Spain and sending it back for repair would be costly. Wondering if anyone knows of a person or company who can resolder it back on?

    Capacitor is about 5mm wide and connects on a circuit board fairly close to other parts of the circuit making it a delicate job (I can supply a PDF showing the repair in advance)

    Re: So... is there a localish soldering expert?

    If it conventionally mounted, it should be straightforward - if it is surface mount - that is specialist stuff. Conventionl soldering is fairly easy (I've just repaired a couple of cct boards where the capacitors have failed - and obtaining the parts isn't difficult. Pic would be useful! Unfortunately I'm not local - is the board postable?

    Re: So... is there a localish soldering expert?

    If you're talking about the black capacitor, what's exactly wrong with it? Has one of the places where it's soldered to the surface mount capacitor come away slightly?

    If so, I'd say anyone with a half-decent soldering iron, and a tiny bit of flux could reflow that solder joint in about 10 seconds.

    That's some shonky board design though. Just awful. In fact, it looks like a plain hack for some additional decoupling maybe? I'm not so good at electronics these days.

    Re: So... is there a localish soldering expert?

    Hmmm - agree with Fraz - not very clever! Yes, it could be repaired, but although I'd probably attempt it on my kit, I wouldn't like to try it on someone elses! I suspect that one of the joints was dry if the lead has come away from the land - caused by someone not wishing to risk dislodging the SM device - and therein lies the risk.

    Re: So... is there a localish soldering expert?

    Yes it is a "hack" basically, it's supposed to damp down interference on the RS-232 socket that connects to an additional device that basically gives the unit more processing power and capabilities.

    The solder has come away whilst the machine is in the post back to us to get updated, ideally we don't want to charge the customer any more than we need to but lack a decent soldering iron. What's more annoying is the machine works more or less fine without this, as it's a "just in case" thing rather than needed all the time!

    Re: So... is there a localish soldering expert?

    If addng the capacitor was part of the modification, I'd be tempted to send it back as the job wasn't done properly - the capacitor should not have come adrift if it had been soldered on properly.

    However if time is important, it may be quicker to buy a soldering iron and do the repair yourself, although you then carry the risk if anything untoward happens.
