In Reply to: How do you unsolder DIL8? posted by groman on January 5, 2002 at 05:45:32:
I use a low wattage iron(about 10w)and a solder sucker.It usually takes a couple of times with the sucker to get enough of the solder away from each pin,so that you can finally free the IC from the board.Once you've gotten the IC out,check eack hole for leftover solder,etc..Make sure each one is clean.Look at each of the solder pads and if there's any excess solder,go at it with the solder sucker.Install sockets,watching for the notch on end to correspond to what was on the board.Sometimes they're marked on the board.Actually, that's the very first thing to do.I'm assuming you'll be reading whole post before doing. Now some folks get really tweaky and couldn't stand to have that socket in there,but if it doesn't bother you,bend the socket leads over so that they touch the solder pads,or get close.This will help hold the socket in place while you're moving the board around and will help improve the contact between socket and board.Solder the socket in place and get ready to install the new IC. Installing and removing IC's is tricky.Some people use special tools.It's VERY easy to bend the pins and screw one up.Look at the IC and make sure all the pins are straight and in line.I hold the chip by each end and get one row started and then gently push the chip so the other row can fit into the socket.You'll see what I mean.Trying this a couple of times on something else is a good idea.Once you have both rows engaged in the socket,make sure it's seated. When it comes time to remove one,I try to carefully pry up each end a little bit at a time until I can pull it free with fingers.There is a tool for removal that's U shaped and grabs under each end.It works. This stuff CAN be done.Be careful and take your time.It takes a while to get all the connectors marked and unplugged so that the board can come right out.You might get lucky and have one that will tip over without disconnecting everything.
