    The solder cools as the air hits it so short burst is enough. One of those "cans O air" works well.

    Blowing through a drinking straw will also work. Not much air is needed. As long as you do not hyperventilate.

    Wait for the solder to just start flowing and apply air.

    I use this often, I make many mistakes!

    Hi Dave,

    Using fine tipped cutters, clip each pin as close to the IC as possible. Then with needle nose pliers holding the clipped end of the pin, heat the solder joint and pull the pin out. You must be carefull when pulling on the pin just in case the pin is bent over on the solder side. I use a solder sucker to remove the excess solder. Sometimes you need to put some more solder on the joint to use a solder sucker or wick but I have found it to a very good method.

    HTH,

    Chop the legs off the chip as close to the body as possible - leaving as much on the PCB as you can to grab in the next stage. A good pair of flush side cutters should accomplish that. One at a time, heat up each joint and with a pair of long-nose plyers pull the pin out through the top (you should have left enough of the pin in the previous step to grab). Use a standard $5 solder sucker with a half-decent nozzle to SUCK the joint clean... digressing (only slightly) - what I don't understand is why it's called a 'Blow Job'... - but I could be on the wrong forum again....

    I was thinking about cuttin the legs off. One thing i normally do for small circuits is heat it up then drop it and the solder falls off onto a bit of wood. Thats hard here though because theres more components under the chip. I think cutting it up then blowing the solder off is the best option based on the tools i have
