How do i remove factory installed chip sockects on a pcb

I need to remove some chip sockets on a pcb...the sockets are so close to the board i can't get my snips in between the socket and the board to cut the legs...they are very flush with the board.....and i do have a hakko desoldering gun but the solder on the soldering side is so small and flush with the board im having a hard time removing the solder.

Any suggestions?
 
What PCB are you working on?? On some of them (Williams and a few others), you can remove the top of the socket, and desolder the pins one at a time.

What yaryar said and what HudsonArcade said
 
There are some really good youtube tutorials on removing through hole components. I know there's one that I think Adam from OneCircuit did on this and it was excellent.

But the easiest method that I've found is to remove the plastic body of the socket first. If you can't lift the body off easily then you can use your flush cutters to cut the socket into sections and remove it in pieces. Then carefully heat and remove each pin one at a time using a pair of tweezers to lift the pin from the hole. Once the pin is removed then you can use your desoldering station to remove the solder. Then use some flux and a solder wick to clean up each pad if needed. If the solder is hard to remove, then add new solder to it, and then attempt removal again until you get it. It is a lot easier to do this after the pin is removed. If you are using a desoldering station make sure you are using the correct tip size that matches the solder pad. If your tip is too large it will not remove solder very well.

If you don't own one of these, I would recommend it.

I second this.

single wipe sockets as noted above (indicative of you being able to only see the socket pins through the slots) will have removable plastic housings. this may work on Nintendo boards too, I had to change a Z80 socket on a Popeye once without much grief, but probably used the FR300. the premise however is once you remove the housing you'll have the pins exposed.

the strategy I use is add solder to all the points, and flow it properly all around. then melt the point and press down on the pin. once you get them all up high enough, flip the board over and with a 90 degree pick hook the pin, touch your iron to the joint, and lift the old pin out. do this until they're all removed. then you use the solder sucker with greater ease and greatly diminish the risk of tearing up your solder pads trying to desolder the pins straight.

in the case of dual wipe sockets, or where the pins overlap the housing, you just have to desolder the socket straight. use flux if necessary and make sure you reflow very well first.
 
My method is to
1) reflow solder as others have mentioned
2) I've got a board holder that I stand the board up so both the solder side and parts side are accessible.
3) I heat the leg of the ic on the parts side, then use a RadioShack desoldering iron and pump from the solder side of the pin I am working on. Often the solder is on both sides of the board and that's why I heat them simultaneously.
4) Before pulling the chip out, I push the pin on the solder side away from both sides of the hole to ensure it's free from being soldered to either side (this will help to not pull pads out accidentally) if the legs isn't free yet, reapply solder and repeat step 3. This is the method that works best for me
 
i don't own a hakko but my edsyn zd500 has many different tip diameters and if not using the correct one that definitely don't work as well for those smaller holes. does the hakko use different tips??

Hakko 850 (CAUTION edit: apparently this link is a knock-off brand called Quakko):

Yes. 1.0mm is the standard that comes with it. I use a 1.3mm for thinks like Flybacks, etc...
 
Do you know if the IC's survive this method of removal or is it just to remove them without concern of them working afterwords?

Not sure, it's Clay Cowgill's vid. Are you concerned about the heat? It does appear to be the least invasive, the other method I saw was snipping all the legs...lol
