To remove solder balls and improve overall cosmetic appearance.

How to clean no clean solder flux. Using a cotton swab or acid brush cut as Pete stated soaked in alcohol helps to break down and remove. 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. Yes solder can be used without flux.

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. Step 1. No-clean fluxes leave much less residue behind than the conventional R type flux and this smaller amount of residue will usually not interfere with the operation of the board or cause long-term corrosion-related failures.

Could you advice if our process is right and could you recommend any better solutions andor. The mixture works on both resin and non-resin based flux as well as no-clean flux too. Any of betaine glycine alanine beta-alanine or GABA or a combination of these totalling between 1 and 5.

This depends greatly on what kind of solder and flux you used. In order to effectively clean and remove no clean solder pastes and no clean flux residues a polar solvent or a solution of water and saponifier is necessary. No-clean solder pastes cannot be cleaned with water alone aqueous based or solvent based cleaning agents are necessary Automated cleaning systems such as conveyorized inline cleaner or a dishwasher cabinet style batch cleaner may be required with the use of aqueous or solvent based cleaning.
