If you have to remove many of these connectors, the solder wave or solder pot solutions are best. I have removed a single connector (like this one) with the following process: 1. Strip a piece of wire from some house-wiring cable to retrieve a length of 10 or 12 gauge copper wire the length of your connector. 2. Roll this piece of wire between two flat surfaces to remove any kinks. 3. Coat it with a generous layer of solder. 4. Position the board such that the connector can fall down (or be pulled down) without interference. 5. Add gobs of solder (a technical term) to each pin of the connector, forming a solder ball at each pin. 6. Lay the copper wire (heat spreader bar) across all of the solder-balled pins. 7. Heat the copper wire with two (or more) medium to high wattage irons, adding solder as necessary to form a continuous bar of molten solder across all of the connector pins. 8. If the connector doesn't drop out, gently pull it out of the holes after all the solder melts on the top of the board. 9. Lift the wire from the board (while maintaining contact with the irons) with your favorite grabbing tool. 10. Remove excess solder from the holes and clean the board as necessary. Warning: take precautions to avoid injury from excessive solder dropping or splashing from the board as the connector is removed.

Count to 5 and gently pull up... have an assistant turn the wave off. We have also replaced connectors this way, on occasion. Very handy for very large connectors, but otherwise not recommended... and keep in mind that there are lots of very hot things in there where you usually don't stick your hand. regards, Graham Collins Process Engineer, Northrop Grumman Canada Corporation Halifax (902) 873-2000 ext 6215 >>> [log in to unmask] 11/05/04 12:04PM >>> Try this method using a scrap board first to get a feeling of the fine details. Mask board area around the connector with hi temp tape or other material. Preheat board in an oven. Place board on a solder wave fixture. Have one person slide the fixture over the wave till connector is right over the solder and another pull up gently and easy the connector after about 8 seconds.

I need to remove a 72 pin through hole connector. However, I am not able to remove the connector using solder iron & solder sucker. I understand if I am to use solder pot, I should be able to remove it. But I do not have a mini-solder pot. I am wandered if there is other way to take out the connector. Can someone help to advise me other methods to remove the connector. Thanks.
