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

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

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

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

Good day everyone, I'm hoping that there are a few of the Westek Ionic Contamination Tester systems out there... I am in need of standardization solution for this unit and my current suppliers have dried up. I was purchasing from Stoelting, #1-67

Gold should not be corroding in salt water. I have swum hundreds of miles in salt water with my wedding ring on my finger. My ring is a shiny and corrosion-free as the day it was cast over 120 years ago. It's possible that your gold thickness of 0.0
