Vinesh: You�ll find no papers that "clearly describes the harmful effects" of your style "of white residues," because no one is crazy enough to brag that they are doing what your customer wants you to do. The residue of no-clean fluxes are designe

While there may not be any specific requirement to cleaning prior to coating, cleaning an assembly prior to coating will only serve to increase the reliability and integrity of the coating. Some residues from low-solids fluxes can interact with conf

OK� Nap time�s over! Technically speaking, water soluble flux is just that, soluble in water. Technically speaking, one does not need a saponifier or any other chemical agent to remove water soluble (OA) flux residues. However, one must conside

I have had Selective issues such as yours on two very different Selective Solder Machines. I was able to eliminate these issues by using Alpha EF-9301 wave flux with any SAC305 solder. It's a more aggressive flux, but really made the difference. Anot

The residues are from the flux, not adhesive. Do you have flux management system in oven? You also need to check the flux type = can you use low solids. The effect is the same as steam in bathroom - it is cooling affects in exhaust and flux reforming

Residues from what type of flux are you cleaning?

Hi All, We are in the process of converting from RMA solder paste to no-clean process across the shop. This will allow me to carry my semi-aqueous cleaner out of the building and set it ablaze using the terpenes as the fire water. Then I can go ab

Improper washing of water soluable flux residues can be a major contributor to flux residues remaining on the board surface. ;-O That you appear to be only complaining about the pathetic state of the ability of your washer to clean under BGA, it may
