How to remove thru-hole IC from multi-layer PCB?

[Alexandre]

Greetings to all!

I need to safely remove a through-hole DIP IC from an old ISA soundcard. See the picture. The board doesn´t matter and can be trashed. I´m not sure if it´s double-layer or multi-layer. The holes seem very tight on the pins and there´s solder on both faces of the card, on all pins.

I do have some ideas, but not the right tools (I wish I had a Dremel)... So I´d like to hear your ideas on this. All help is highly appreciated!

Thanks,
Alexandre

The best way to remove this IC is by using a very expensive vacuum desoldering iron. Second choice is to get a cheap desoldering iron like the Weller DS-40. You can also use the non-heated pump vacuum type in combination with some type of solder wick. In all cases, you should also use liquid RMA flux. Flux is your friend.

It is much easier to save the board than the IC. It's hard to get a DIP package off a through hole board even with a good solder sucker.

If itbwere my problem I wopuls suck out as much solder as possible and if it still doesn't come out gently, I would get out the Demel tool and cut the board *carefully*right up to the pins to expose them the complete the desoldering

use solder braid in combination with a good soldering iron.the braid can easily suck out the solder,the ic will come out easily.

Depends; some do, some don't.
If it doesn't come out by removing solder,use the opposite method: Melt lots of solder and spread it down each row in turn. The IC will fall out by gravity. Do the job as quickly as possible with the highest wattage iron to hand - 2 if you have them.

If you don't care about the pcb, use fire! Cigarette lighter or gasol burner.

as you dont have a dremel you could score along where you want to cut then snap the board. You have to make a deep score and bend it slowly tho. The blue lines on the pic are where you should cut. Make sure you cut right across the board.

Or you can use an electric powered paint stripper, you know that thing that looks like a hair dryer. Heat the board from the bottom side where the IC is located.

Be sure to use one of the thermostatically controlled ones

Thanks for all the replies. I´ve been practicing on some other ICs with a desoldering pump, but I don´t think this will do.

I actually liked the fire idea (by peranders), but I´ll leave that as a last resort!

Someone suggested using two irons at once, thats nice! I think I´ll try bending copper wire to an "L" shape and use this tip on the iron, to touch the entire row of pins.

I´ll let you all know how it goes!

Best regars,
