Is it necesary to repair lifted traces/pads ?
its actually a pad at the end of a trace to mount a wire/pin connection to another board (not a hole) if one does need to repair then how does one ree-glue or repair a lifted trace/pad ? thanks for any help, robb |

Be careful when you solder over it, the fumes are nasty. 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. --- sam | Sci.Electronics.Repair FAQ: http://www.repairfaq.org/ Repair | Main Table of Contents: http://www.repairfaq.org/REPAIR/ +Lasers | Sam's Laser FAQ: http://www.repairfaq.org/sam/lasersam.htm | Mirror Sites: http://www.repairfaq.org/REPAIR/F_mirror.html Important: Anything sent to the email address in the message header above is ignored unless my full name AND either lasers or electronics is included in the subject line.

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. |

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. Agreed. One of the boards that I work regularly on, were previously repaired by an agent whose only soldering equipment appeared to be a gas poker and some plumber's solder. Many of his previous 'repairs', when they show up again here, have lifted tracks and pads that just fall away as soon as you try to remove the bad component that connects to them. I just use the long leg on the new resistor or whatever to connect back to the nearest undamaged point - either tracking that's still in place and can be scraped back and soldered to, or the next genuine solder point up the track. If a pad is still in place, just 'flapping free' of the board, it can often be re-attached just by heating and pressing. The original glue will remelt and stick it enough to work with. I try to avoid superglue as it fumes badly when heated and is a killer if you get it in your eyes. Remember that forensic scientists use its fuming and recondensing properties to highlight otherwise invisible fingerprints ... Arfa |

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 |

glue that is now outlawed. You have to wear a face shield when applying in a very opened or ventilated area. You place one compound on one piece while you place the other compound on the other piece to be joined. Nothing takes place until you actually join them. You have to be rather quick in getting them into position correctly. It gives off a mist that is very toxic. This is for industrial use only and requires a on sight [sic!] permit to use it. 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. |

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). Theo |

Theo At work, some of the products that get manufactured there uses a copper tape with an adhesive backing that requires heating prior to be laid on the surface. I keep a small piece in my drawers when I need to repair a board. I just cut, press and hold with the soldering iron. It's a high temperature glue that is inductive heated at process time while it's being wrapped around a cable core. The inductive heater and controls was one of my projects and the mechanical was done by the other skilled personal. The whole project was credited to a process engineer that did nothing but probe all us for idea's and had us implement it. And when it's time to go home for the day, they don't know you any better than the day of your hire. That's gratifying to say the least. -- "I'm never wrong, once i thought i was, but was mistaken" Real Programmers Do things like this. http://webpages.charter.net/jamie_5 |

I'll be getting to the other topic presently. 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 ... Arfa |

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. robb |

I believe there are clearly Brit (or perhaps Continental?) influences in both of them. Regards, Michael 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 ... Arfa |

Poster's remarks were rife with other structure, grammar and punctuation errors. Laugh all you want guys. The tab is on me. And yes, I can understand you guys over there in England. The language in the states is full of twisted slang how ever, I do understand the brothers over here want to reform our language. ![]() Who knows, pig Latin in school might be refreshing! It sure would give the boys in mother England something to talk about, more so than ever. I took real Latin in secondary school, and over the years, it's proved really quite useful in working out the meanings of words, as many have a Latin base. Sadly, the very great majority of government schools no longer teach it. It has been replaced with other useful subjects like how not to get pregnant, and making the best use of the social security system if you do... Arfa |

You place one compound on one piece while you place the other compound on the other piece to be joined. Nothing takes place until you actually join them. You have to be rather quick in getting them into position correctly. It gives off a mist that is very toxic. This is for industrial use only and requires a on sight permit to use it. Now we can't get any more, but still have a rather good supply of it. When you need to do things like bonding Nylon, Teflon etc. that is what we use. Why is it "outlawed"? Or another question.. What is it? Or where this shop is, so OSHA can shut them down? -- Service to my country? Been there, Done that, and I've got my DD214 to prove it. Member of DAV #85. Michael A.

Just not legal any more to buy it and in the first place it was a specialty product for industrial use only. If I remember, i'll get the chemical composition of it this week in work. -- "I'm never wrong, once i thought i was, but was mistaken" Real Programmers Do things like this. http://webpages.charter.net/jamie_5 |
