Is it possible to replace fried PCMCIA connector ???
Last night I inserted a PCMCIA card adapter into the PCMCIA slot and smoke started to pour out . The PCMCIA connector fried on one of the pins .
I have tried this card once before and it did not work , so I tried again last night and the above happened . Is it possible to replace the connector ? If so where would I get one from ? Please dont tell my im screwed and need a new motherboard Any help from you good people is greatly appreciated . http://eab.abime.net/attachment.php?...2&d=1272456330 |

See if you can get hold of a scrap (non-working) A1200 or A600 motherboard, and take the PCMCIA connector from that.
This will give you some practice at removing another PCMCIA connector before you attempt the one on your existing motherboard, to minimise the chance of lifting any pads. |

It will not be an easy job.
I have not replaced a PCMCIA connector before, but I have replaced 72-pin SIMM sockets, and I would rate them about the same in terms of difficulty. You can destroy the one you are removing from your existing motherboard by carefully crushing and cutting away the plastic, so that the pins will just fall out of the motherboard when the joints are heated. It goes not matter if you lift some of the pads from the donor motherboard whilst you are removing the replacement connector. Then you should just clean up the pads on your existing motherboard, removing excess solder with solder wick in preference to a solder sucking tool and fit the new socket and solder it in. Remove any flux from the board with isopropyl alcohol or methylated spirits to leave it looking clean. It would be best to use a temperature-controlled soldering iron for the job. |

Just realised the plastic mount will not take kindly to heat gun EDIT: I do have a very small nozzle for it so I can always test it on removing the old one and see how it fairs . |

In circumstances like this, it is recommended that you mask exposed, heat-sensitive parts from the heat gun using silver foil. |

I have an A1200 with pin 44 and 43 missed in the IDE interface. Sorry about this 'cause this Amiga works perfectly, but I believe it could never have an hard drive.

With a hot air re-work station this is relatively simple
ingredients -
Method
All I can say is go slowly and be gentel and you will save the port and board. REMEMBER ALWAYS CLEAN, both the PCB and component. most Fluxes are corrosive so have at it with IPA / Diluted Car Screen wash - worse case washing up liquid and water! Quote:

My question is, what smoked?
PINs from a connector don't usually smoke.... Was it (hopefully) the PCMCIA card you used? Or did something on the motherboard other than the connector loose it's magic smoke? I'd carefully look at the components... desiv |

Thanks Zetro , Most informative
By rights should be able to pull the connector off in one go and clean solder afterwards . |

The Remainder of the pin is welded inside the PCMCIA card adapter . Card adapter must be faulty . |

I find that the amount of heat required to melt/smoke plastic usually isn't to good for the electronics connected to either end of the pin. But it could be... I've seen some seriously damaged looking electronics still work! Good luck! desiv |

Fingers crossed . A1200 still works and worked fine without smoke till I inserted the card adapter . But your right the pin burned like a fuse wire and its not exactly a fine pin either .

Your best bet is to look on Ebay for connectors and alike, Hong Kong is the flavour of the month or China, they usually have heaps of these sorts of things for very little and free postage.
