Rather than cleaning a water soluble flux residue off the board, by encapsulating the product. covering the board or the component with lets say a Hysol encasulant. Would this prevent the active flux residue from migrating and deteriorating the elect

Steve, Water-soluble fluxes are per definition very corrosive and need to be cleaned (read the data sheet) Encapsulation will prevent humidity reaching the water-soluble acids but will not prevent reducing the metals the flux is in contact with to m

I had problems with white residues on both WS609 and WS 3060.The WS 3060 turned out to be a carbonized material.The composition after analysis (Energy Dispersive X-ray spectrum) turned out to be tin,tin,phosphore and cloline and tin. Alpha also have

My company currently uses water soluble paste for our SMT process. We were having trouble retaining hot water in our in line, closed loop DI cleaner. The cleaner kept shutting down when the water temp. dropped below 125C. As a result, the conveyor

Greetings All, Anybody out there experiencing white residues after cleaning? We currently use a batch cleaner to clean water soluble fluxes. this cleaner makes its own DI water by means of carbon and resin tanks. After cleaning there are residues

There should be no problem. Recognize that the residue of some low residue fluxes turn a milky-white color when you wash them. This could freak your quality people.

Davef is right on as usual. We are doing exactly what you do. Some smt with no clean paste then the plate through connectors on our selective solder machine using water soluble flux. We then clean with a ultrasonic water process. We do see the re

It realy depends on what no-clean you use, I had on that would get under IC's and not get fully activated it was fine here in the states but when it was shipped over seas the salt air and humidity gave us fits, another we used didnt have that problem

At my last place of employment, that was the big reason why nobody (especially the Design Engineers) bought into a no-clean process - interference with high-impedance circuits. One guy was so paranoid about flux residues remaining on the board, that
