Adam, You might try marine products such as 'Salt Away' or 'Salt Terminator'. These are made to get rid of salt residue in marine engines used in saltwater applications and are not harmful to standard wiring. They are available at marine stores al

White residues

MadReindeer If this white residue is salt, * Why do you say is the presence of it 'not dangerous it only looking bad'? Don't salts sometimes go into solution with moisture on the board from humidity in the air and form cathodic plating shorts betw

Sorry if I was not clear. We have a Flex Circuit Board that is ENIG Finished. There are two connectors that are SMTd to either side of the Flex to connect to other PCBs within the system. Then, we have conductive rubber contacts that are press fit on

Dear adam Sounds to me like it may not be Salt water contamination or even flux residue's, as both of these are commonly cleaned semi aqueosly or with IPA. Have you considered it may be Talcum powder used as fillers in solder resist, mineral salts

we have more of a problem with transfer of salts from skin onto the products. Oils ect can be cleaned off in our solvent based cleaning system which we put everything through, but the only way to remove salts is with warm water. And we dont use a wat

5000 hours, yeow!!! Salt spray testing "periods range from a few hours (e.g. 8 or 24 hours of phosphated steel) to more than a month (e.g. 720 hours of zinc-nickel coatings, 1000 hours of certain zinc flake coatings)." Look here: http://www.ancatt.c

Mario: Your ask a very broad question and give no background information. Generally, the amount and type of residues present on a printed circuit board at the very beginning of a SMT line depends on the exposure of the board up to that point. For

Flux residue on connector pins

Electronics Forum | Sun Aug 29 19:17:34 EDT 2004 | aqueous

Chen, It is always best to place one�s effort on determining the cause and content of the residue rather than trying to work around it. The first thing you must determine is the nature of the residue. Is it flux? In many instances, the residue is

Conformal Coating Immersable in Water

Parylene is arguable the best conformal coating there is, unfortunately it's also the most expensive. We had considered using it some time back, but due to environmental and safety issues, we would have had to build a new building to house the proce
