How To Clean No Clean Solder Flux
The no-clean flux residues are more difficult to remove than other fluxes.
How to clean no clean solder flux. This solder paste exhibited SIR value above the IPC spec 100 MΩ without any dendrite formation even with a wet flux residue on the comb pattern. No soldering was done. You have made one litre of flux remover that quantity should suffice for quite some time.
If you are considering an inline system this will raise the equipment price substantially as a chemical-compatible inline cleaner costs considerably more than a water-only system. Cleaning flux from a solder joint also allows for proper inspection no copper exposed. The problem most people find with it is that it has a dark residue and when we used to use it on Printed circuit boards the test folks would get upset because it would foul up their test fixtures and test pins.
Most assemblers in the electronic industry use no-clean solder paste mainly to eliminate the requirement of cleaning the circuit board. Percentages are by weight. After soldering we using Vapor Degreaser process with RHO-TRON 225 AES-L to clean up the flux.
You dont have to clean an RMA Flux. Avoid no-clean soldering flux as solvents it cant remove these. No-clean fluxes were designed to help circuit board manufacturers skip the time and expense of cleaning the board after soldering.
The flux will be activated by the heat that will start a chemical reaction to eliminate the oxidation. This depends greatly on what kind of solder and flux you used. Always wear gloves before you handle the ethyl and isopropyl solutions and start mixing them.
If you are using our 4140 Flux Remover you may spray it liberally as it is safe on your components. But for wires this was and still is the flux to use. The flux hardens and can be left on.
