Desoldering Trick for Through-Hole Parts

Although MS pcb holes are generously sized, removing parts, especially chips and sockets can be difficult for the beginner.
Chip Quik may help. It's made for surface-mount desoldering but I use it for tight through-hole components that won't desolder well with my tools. Not cheap but better that pulling a plated through-hole out.

It's low temp solder that stays molten long enough so you can just pull the part out; then clean out the holes. About 15.00 for a kit with flux.


No affilation other than being a customer of Howard. Just occured to me it might help.

Don't forget to use pricing code of MEGASQUIRT if you order from Howard. I think he still gives an additional discount to this group for solder stations and maybe supplies as well

I use a vacuum desoldering tool and it works great. Just heat up the joint and suck up the solder. I think it cost about $6 and it has come in very handy.

I usually snip the legs off of whatever I'm desoldering (provides some satisfaction :twisted: ) then use solder wick.

Admittedly low tech, but I get frustrated with all the maintenance solder suckers require. I usually get too much heat on the board using suckers. With Wick, the thru hole is usually cleaned up nice and bright.

Wick also doesn't require a third hand with trying to hold the board, Iron and working the sucker. For Wick, press the wick onto the hole with the iron. It helps to apply a small amount of solder to the iron to get the heat into the wick.

Just my $.02

Good info to know, me being a electronics novice I didn't know "wick" existed. You learn something in this forum every day.
