I've tried it, crushed & powdered standard violin rosin and dissolved in 91% isopropyl alcohol and it seems to work fine as a liquid flux for soldering/de-soldering. I didn't measure anything, just put enough powdered rosin in so when completely dissolved and set for a while there's a small layer of thicker mixture of rosin at the bottom of the bottle that mixes in when shaken before use.

Re: Violin rosin used as flux
Yeah, I got the idea from the same eevblog link. Thanks for the other links. Personally I like the smoke, it is incense to me. Reminiscent of Christmas trees and campfires.
Being a (retired due to arthritis) musician I had a block of violin rosin hanging around with nothing to do so I've put it to use. I figured why spend money for something I can mix up right here with what I've got. I don't have any glycerine on hand or I'd have tried a drop or two of that for fun. I highly recommend a dropper over a syringe though. The rosin makes the syringe plunger stick and you wind up with a lot more of the liquid all over the work than counted on once the plunger finally moves. I haven't tried making it thick enough for a paste or goo yet, The liquid as is works fine but it does drip and run if using too much.
Mixing the rosin into 91% alcohol it did not take long at all to completely dissolve, only a hour or so.Comment

Re: Violin rosin used as flux
I have some MG Chemicals liquid flux that smells like this, so I think I know what you mean
. It is good for general soldering, but not so much for BGA since it evaporates and dries too quickly and usually way before the proper temperature has been reached for the reflow to take place.

Re: Violin rosin used as flux
I also spreads over the board real fast. Perhaps adding the glycerine will help for those issues. I'll have to get some and try adding it.Comment

Re: Violin rosin used as flux
Same for the paste flux in syringes they make... good for BGA work though. But very smoky and smelly...I have some MG Chemicals liquid flux that smells like this, so I think I know what you mean .

i recently bought a block of solid rosin flux from aliexpress. i intend to use it for reflowing cold solder joints and cracked solder joints. but im not sure how im supposed to be using it? do i just break off bits and pieces of it with a knife and put the bits of solid rosin on the bad joint im soldering then bring on the iron?
i tried asking google and they pointed me to a headphone forum and eevblog? and they said to just dip the soldering iron tip into the solid block. a small piece of flux will be attached to the soldering iron tip end and im supposed to use that to reflow... -
I want to purchase any good flux remover But "chemistronic flux off es835b" is the most common flux remover in my nation..
Is it good to use chemistronic flux off es835b for flux remover?
Or I have to purchase "3m novec flux remover" which is quite expensive in my nation? -

Now that my de-soldering gun is working i was able to remove this panel i made about a week before i noticed a issue the F segment of digits 2 and 3 would go out, digit 2 would go before digit 3, but would come back after the humidity got down from running the ac (note the weather outside is 30.5 / 74%; panel data is from a BME280)
Temp is on the left humidity is on the right
i noticed when the humidity got up one or 2 of the center digits on the right panel would loose a segment
The pin out looking down from the top is (note this is common cathode)... -
I have tried to bridging tiny broken trace which is shown in the below link,and I found that it is impossible to remove any flux after soldering task.
Is it possible bridging tiny broken trace - Badcaps - Capacitor Search Engine
Because the 0.02 mm copper wire is very very fragile,So It broke itself very easily whenever I tried to rub excess flux with cotton bud.
Is there any way to remove flux with the smallest rubbing or without any rubbing?
Any reply would be appreciated.
