#Rosin flux removal free#
After a minute I put a lint free cleaning wipe over it and start brushing over with a toothbrush or small painters brush. I spray the flux remover onto the contaminated area and wait a few moments for it to start dissolving the flux residue. For practical purposes I pour some of the flux remover into the 100ml spray bottle and save the rest for later use.Īfter every rework on a printed circuit board, I remove the flux residue for the above mentioned reasons. You have made one litre of flux remover, that quantity should suffice for quite some time. Add 100ml of Isopropyl alcohol and 50ml of Ethyl acetate to the 850ml of the Ethanol in the container. Take a liquid measuring cup and pour off 150ml of the Ethanol from the container. If you bought Ethanol in a 1L container, it’s best to use its container for storage of the homemade flux remover. Additives such as water greatly reduce the cleaning effectiveness and could leave residues on the board. Purity of the Ethanol and Isopropyl alcohol is essential, both should be at least 95% pure. Work in a well ventilated area and remove all sources of ignition. Safety first: put on protective gloves to avoid damage to your skin. If you use different units, please use a friendly liquid volume converter – Mixing procedure 50ml Ethyl acetate (also called: ethyl ethanoate, EtOAc or EA).100ml +95% pure Isopropyl alcohol (also called: isopropanol, 2-propanol, IPA).850ml +95% pure denaturated Ethanol (also called: ethyl alcohol).It can be used on circuit boards and on most of the plastic parts (discoloration may occur on some plastics). It works better than some commercially available products and it doesn’t leave any residue when used properly. The homemade flux remover is able to remove the rosin based, non-rosin based and no-clean flux. to improve the cosmetic appearance of the board.it prevents an adhesion of conformal coating.
gummy residue prevents test accuracy when doing in-circuit testing.Rosin flux is highly corrosive so it needs to be removed after soldering, still, why would you want to remove a no-clean flux residue? There are essentially three types of flux – water soluble flux, no-clean flux and traditional rosin flux. The contaminants could be removed by mechanical or chemical cleaning prior to soldering, however, high temperatures required during the soldering process would cause an element to re-oxidize and thus prevent a successful solder joint. By removing impurities such as dirt, oils and oxidation, it helps to achieve a stronger solder joint. The use of flux is essential when soldering electronic components.
