Best way to pull SMD chips off without a solder sucker

Solder wick and some liquid flux (if you've got it). Heat it. Wick it. Flux It. Wick it some more. Gentle lift up each lead if you have to. Then work around the part until it is off. Sometimes adding more solder and rewicking gets the job done.

Here is a post I started a while ago about removing SMD chips: link

Good suggestions there and most people don't even mention a solder sucker.

a quick and dirty way is to just rub your iron over both sides of the chip quickly while wiggling the ic with some tweezers. Usually lift one side of the chip at a time. Careful not to pull a pad though.

jefemeister's suggestion is very practical and the same method i use. but if you have two soldering iron with fine tip, you could use them like tweezer to pull out smd components like resistor /capacitor.

for smd chips, what i do is lift up the legs one or two at a time with sharp pointed tweezer or blade while heating the pins. you would need a magnifying lens to aid you. care must be taken not to over heat the pads.

the most convenient method that i tried so far is using a hot air station. such equipment has the ability to heat up all together the pins, lift out the smd part by using tweezer.

"For removing surface mount chips, if they're two sided, I cover one entire side of pins in moltent solder and with a jewelers screwdriver I lift up the chip about a mm or so. Then I use solder wick to remove all that excess solder on that side, leaving one side free. Then I do the same thing to the other side - remove excess solder - and I'm done. Quick and easy. But the important thing is to be very fast - you don't want that hot solder on there for too long, otherwise the chip can get damaged."

I was about to say I completely agree with that - then I realized you were quoting me.

If I'm removing a smd resistor I no longer need, I'll just coat the entire part into a blob of solder. That removes the entire piece from the board very easily.
I did that on my old Geforce video card when I removed the low-pass filters for better image quality.
For the Quadro mod (shifting resistor), I used jewellers screwdriver to lift one side and then the other.
