I received 5 oz of pine rosin finely powdered I bought on e-bay. So following on the reply to my question, I mixed up a trial batch consisting of 20 gm rosin powder, 0.40 gm (0.2%) citric acid, 0.2 gm glycerin, 20 gm 95% isopropanol and one drop of Joy dishwashing detergent (nonionic surfactant). With intermittent swirling, the power appears to have fully dissolved in a couple of hours at ambient temperature. In initial trials using old stranded copper wire it appears to work just as well as the MG Chemicals liquid rosin flux I had been using. To dispense it, I am using a one ounce plastic bottle with a needle in it (sold as a glue dispenser for hobby applications). That allows me to put the liquid flux right where I want it and not have a brush to clean up every time I use it. I'll report back if I have any issue, and thanks again for the information on how to do it!
Thats pretty hard to tell. Since you don't want to eat away your traces you should be very carefull not to overdo it. I personally used only a small amount, like.... hmm... the tip of a knife?
@@TinkertubesLab OK, thanks. Good to know. I think I may just try the straight rosin first by itself. It may be good enough for my uses and then I won't have to worry about corrosion. Nice video, by the way. Thanks for posting it.
@@JohnClulow Thank you very much for your feedback :) Maybe there will be a new video in a few weeks - havent posted one in over a year :O Would be glad to see you there again :)
I've heard heating the mixture or partial mixture will cause it to gel. Danger is though this mixture it bad if it catches fire. Any other ideas on 'gelling' the mixture

Hi Dr. Smith, I didn't weight it to get exact measurments. I just stuffed as much rosin chunks into the flask as I could fit in there and topped it with alcohol. This could very well be even more than 50% rosin. Just try to stuff as much in there as possible.
My hearing is a bit bad, could you please write the ingredients for all 3 types, fully activated, mildly activated and inactivated flux? If there are proportional amounts could you give those to me as well. Example To make inactivated flux: Fill bottle with rosin, top off with 99.9% ISO alcohol and shake, put away in warm place and shake bottle daily for 2 weeks until rosin is fully dissolved, if alcohol is evaporated refill bottle with alcohol. I hope I am not asking for too much but thank you for your consideration. :-)
That is basically all you need for standard rosin flux :) To activate it just add some acid. Many people use aspirin to get the salicylic acid, but there are also many additives and filler materials in those tablets, so I don't personally like that. I prefer to use citric acid, which is easily obtained as cleaner for coffee machines. Just add a bit of that, more or less "to taste", and you have your activated flux done in no time :) How strong the activation is is dependent on the type of acid you use and how much you dissolve in the rosin flux. Hope that helped you :)

@John Doe Not sure.... citric acid is a weak acid, but I don't know about the need for clean-up
Still using it although I'm not doing nearly as much electronics work anymore as I'm getting older
@@JohnDoe-u3b still using the same batch
Pretty sure you have to distill it in order to remove minute organics
add few drops of glycerin to make the solution non-sticky, also improves solder flow,
good idea i vape and got my own VG , just made a flux 100ml bottle well i think i did lol so a odd drop will do it?
Gum rosin makes better flux paste making but add mix what is solvent camical please 🙏 explain name please 🙏 😀
Isopropyl alcohol (rubbing alcohol)
It works with Ethanol too.
Use high purity 99%+
Dear Sir zee india 🇮🇳 rosin flux paste home makeing add &MIX TRICHRORETHYLENE CAMICAL VIDEO 📹 PROVIDES PLEASE SIR 🙏
Violinist apply rosin to the bow to improve its friction against strings so the sound will be better and louder
When you use citric acid to improve activation, about how much would you add?

i like that solder wire holder i take it you made it i can do that, that's how i say isopropanol it never comes out right lol
Could this also just be applied with a Q-Tip (Wattestäbchen?) :D
Absolutely yes, I do that regularely
Нow to make a tacky gel flux similar ChipQuik SMD291?
I am experimenting on making something like that. If I find a way I will let you know.
Thanks, I'll be wait :o))
Ваня Иванов Add 10ml of 90% alcohol,5g of rosin and add vaseline until you like the consistency

Much better to use naphthalene acetic acid, (NAA), because although is very good at dissolving any oxidation, the residue is not corrosive.

Thanks for the tip, I will try it :) Where can you get it for cheap as a hobbyist?

What % of alcohol and rosin did you use? 50% + 50% ?
Hi Dr. Smith,
I didn't weight it to get exact measurments. I just stuffed as much rosin chunks into the flask as I could fit in there and topped it with alcohol. This could very well be even more than 50% rosin. Just try to stuff as much in there as possible.
What if i use ip and rosin
Well, that is exactly what I used to make that stuff.
@@TinkertubesLab I want to say local ip. Mixed
Well, why don't you just try it? :) I never did, so no Idea what should happen.

are you a chemical engineer?
No, I am an electronics technician and right now studying to become an electronics engineer.
@ulol metro I'm fine, thank you.
Where is the rosin come from
Ebay :)
Trees :D
Thanks
It came from pine tree, instead you can use Arabic gum it will give same result. Search google to be sure
I love your video. It is always great to have humor!
