hi guys
im looking for a decent tweezer style desoldering iron

the type you can slot down the side of ic's and heat all the legs at once

i think on older boards this would be an easier way to remove the old ic's without damaging the trhough holes on multi layered boards

thanks

I find that a good hot air station in the right hands has more uses than just a tweezer.

One issue is that you might get the IC out, but all the holes will be flooded with solder, so you'll still have to suck it out.
Can't say I've tried such a tool though - I use a Weller solder sucker station and it still takes me AAAGES to remove devices, especially intact.

I had one of those Weller stations, it doesn't help they're 30 odd years old but they aren't great. You need to get yourself a Hakko John, they need constant cleaning but they remove the solder / chips fairly easily and quickly which means less heat on the pcb.

You can tell when someone has used hot air on a dip chip, there's always blister marks and discolouration on the pcb. Hot air should only be used for surface mount stuff imo.

I think tweezers that size would have the same problem of heating the board for too long.

Funny you should say that, my dad acquired a Hakko and it was extremely impressive, so I do need to get one!

The Weller is the same concept as the Hakko (heated tip with a vacuum pump) and probably £2000 new (10 years old now), but it never seems to suck the solder out 100%, so you have to wiggle things around loads to free them without damage. It's not mine anyway, so I do need a Hakko.

the tweezer soldering iron you would not in theory have to touch the board, basically put the 2 prongs heated directly on the legs of the chip till solder is motlern and lift the chip out

any ideas where to get one guys ?

thanks
