Arhi tried his hand making DIY rosin-based solder flux. He added crushed rosin to isopropyl alcohol until it had the desired viscosity.
The video is a test of the new flux on 1 mm and 0.5 mm pitch components. By his account it works better then some commercial products, but there’s also more smoke and residue.

Hi
Nice tip on doing flux, i was looking for something so and tried my own experiments but the results weren’t quite… mmmh nice.
Thank U.
been doing that for ages, but i must say, that because of flux made this way i’ve learned that i really need to clean my boards after soldering them – microcontrollers go bananas otherwise. This flux is conductive as hell.
Can you describe where you got the rosin from? Was it in chunks/sold form -or- liquid/dissolved form?
Also was it _really_rosin or was it a synthetic ‘equivalent’ ?
Pictures would be _great_!
Thanks,
rsk.
I experimeted with rat shack Flux using that alcohol from paint stores. Get a paint filter and coffee filter then dump the Flux in. Throw in the alcohol and wait a while. The precipitate will be an amber liquid Flux and in the filter will be WHATEVER that gelling compound is, but white.
