What are the rosin flux formulas?
I have a book in my hand. The recipe in the book should be available. Mainly ethanol, isopropanol and other solvents, plus rosin, and then add some organic acids and surfactants. The point is, what do you ask? Bought directly, ha ha!
There are many types of flux, different types, and no ingredients inside
The best effect is the alcohol solution of rosin ~ ~!
