how to repair lifted trace pads ?

I have used super glue (ca). Be careful when you solder over it, the fumes are nasty.

Superglue is relatively nontoxic, it's been used to close wounds, but the fumes sure do sting.

If the pad is badly lifted I often just use a scrap of resistor lead or wire wrap wire to jumper the component lead to good trace further up.

It's nice to glue the pad back down but more important to make sure the connection to the trace is secure. Having lifted, it may be weakened and ready to break off.

I agree with the former poster that it's better to solder the lead to the remaining trace. I've done that on several boards, and it's caused no problems.

Thanks Tom, component was allready soldered to pad but pad had lifted (too much heat ?)

so i used the super glue and small spring clamp to press it tight to board ... worked great.

mabe i should paint a small skull and cross bones on top or nextt o pad forfuture reference :) robb

wounds, but the

lead or wire

up.

Thanks for reply,

the pad lifted after soldering the connection, so i wanted to stabilize the pad in case i was too rough or so it would not lean over onto some other trace.

thanks for ideas, robb

it can often

will remelt

it fumes badly

thanks Arfa,

that was exactly the situation... flapping around i tried the super glue before i read your post though

in this case the reheat may not have worked as the under side of pad became contaminated with rosin flux which i flushed before super gling

thanks for ideas, robb

IMO,the only sure way for pad repair is to set an eyelet. You get mechanical security that way,and can replace the component again if necessary without further damage.

Why is it "outlawed"?

Or another question.. What is it?

It sounds as if it's a two-part spray-on adhesive. There are non-spray adhesives of this type, as well as single-component spray adhesives. I'm curious as to what it is, and why it requires an "on-sight" permit. It's hard to believe that a company would manufacture a "highly toxic" spray adhesive.

On SMD boards I've used little slivers of RF shielding tape to make new tracks. It's copper tape with adhesive on one side, you can choose whether the adhesive is conductive or not. The adhesive is just enough to keep the pad in place, and probably enough if the component isn't too big. You can then solder it straight onto the component and an existing track (flux helps here). The biggest difficulty is avoiding surface tension holding it to the soldering iron and coming away when you remove the iron. (Using lead-based solder tends to help here).

I keep a small piece in my drawers when I need to repair a board.

You don't know how funny that sounds in England ... !! :-)

There's some interesting linguisic things coming up this week ! I didn't realise that you used the word "drawers" to mean anything other than its basic over there, or that the American sense of humour made use of inuendo or double entendre. Watching American comedy shows over here, and having visited many times, I'd always thought that your humour was pretty straightforward. Learn something new every day ! Did you see the reply to your question about "going down a storm" ?

I know what you mean, which is why I usually do put the smiley faces. Many is the time that I have 'put my foot in it' over in your fair land, when I have made some straight-faced throw-away comment to a person, only to get a perfectly blank stare back, instead of a "yeah, yeah" grin that I would have got here. I can't remember exactly what it was now, but last time we were over in Florida, my wife made some witty comment to a restaurant server that was somehow linked to his name, and he gave us a look like he thought we were being really rude to him. I felt compelled to explain the 'joke' to him, and when he got it, he was in hysterics, and went away muttering stuff like "boy that's a good one ...!!" I too like dry humour. Some of your comedy programmes go down really well here, as I'm sure that some of ours do over there, but I'm equally sure that many of ours that find their way onto your screens leave a lot of those blank stares behind ... Come to that, they probably do here, as well ...

I sure miss Fawlty Towers; I tried taping the series in one of its 1980's reairings here (U.S.) on VHS but alas its like watching a blizzard out a dirty window now. I wonder if there are uncut episodes on DVD?

Do you have any favorite U.S. sitcoms? What do you think of Married with Children (episodes after 1990 are better) and Two and a Half Men? I believe there are clearly Brit (or perhaps Continental?) influences in both of them.

don't stop there Smitty2, almost all American entertainment seems **engineered** and for what ? i believe mass market appeal as it is considered a vehicle/means for selling stuff and making lots of money. Entertainment lost it's art but every once in a long while some clever entertainment appears and quickly dies because the few 100s thousands that watch do not contribute **enough** to the bottom line.

there are plenty of clever people, just too many numbed by the garbage they let the industry dump into there brains. maybe the entertainment industry will be the next to fall like the **big tobacco**. Scientists prove that poor entertainment does reduce your IQ and dull your wit. Of course there is no law against dumbing people down but i am sure some class action lawyer is working on it.

I used to love "Married with Children". I don't know the other one. Another that I used to really like was "Soap" and also "Cheers". Currently, I like "Scrubs". I think that it is an intelligent blend of humour and serious message conveyed by humour. Everthing in the first half of the show is straight comedy, but with a theme leading to the second half, which often has an underlying sadness. I think a lot of why that show works is the faultless casting. "Friends" worked for the same reason. Did you ever get to see the originals of "The Office" with Ricky Gervaise, before it was remade for your TV using American actors ? Also, did you get to see Ricky in "Extras" ? Although they were a bit variable in quality, when they were good, they were superb. The one with Orlando Bloom in, for instance, was hysterical, particularly the line about Johnny Depp where he said "Willy Wonka ? Willy Wanka more like ! " The one with David Bowie in, however, I thought was poor, and sad rather than funny.

As for Fawlty Towers, that gets run and run and run here. They were talking to Prunella Scales (Sybil Fawlty) on the radio a while back, and I was really surprised that there was only twelve episodes total. She said that in some ways, she rued the day that she ever signed up for it as, considering that there were only 12 episodes, it has defined her whole career in acting. I also saw an interview with John Cleese and Connie Booth (Polly) who co-wrote it with him. They said that most episodes were written in no more than a half hour, and were modified in concept and ad-lib'd a lot during filming. I would have thought that a lot of it might well be around on the 'net for download with a bit of searching - YouTube perhaps? - but failing that, I'm sure it would be available from the BBC website, but whether in NTSC / region 1 format, I don't know. I would have thought that Virgin Megastores would be a good place to look also, as they carry a lot of stuff like that over here, and always look to have very similar stocks in the stores of theirs that I have looked in your side of the pond.

If you want to see some British dry humour with a London East End flavour, check out on YouTube a programme called "Minder". There are loads of clips on there, and you will see where my Usenet nic comes from ...
