This life hack for desoldering multi-pin (multi-legged) microcircuits and parts is different in that it does not require special equipment, or indeed scarce devices. All you need is a thick stranded wire or braid from a shielded cable.
You will also need liquid flux; of course, regular rosin will do, it’s better than liquid rosin with alcohol.
How to solder multi-pin chips and parts easily
For example, it is necessary to unsolder the microcircuit. We generously moisten its legs with flux.
We also generously wet the wires.
And, we lean the wire against the terminals and heat it with a soldering iron.
The solder from the contacts will transfer to the copper wire strands due to the capillary effect, and the contacts of the microcircuit with the pads will remain clean.
In this way, you need to go through all the contacts one by one.
You just have to pull out the chip from the back side.
This method is very easy and simple to desolder any part with a large number of contacts without damaging it.
