Two things ... A friend in the contract coating business said: "... the board is not being baked out long enough, 30 min is certainly not long enough depending on how many layers this board is, as the vacuum (from the parylene process) is pulling t

Ionograph measures conductivity while the Omegameter measures resistivity. They both accomplish the same task in terms of ionic contamintation detection, but go about it a different way. One is really no more accurate than another. For more informati

I would be glad to help you out in recommending a couple of coating choices,(at a very competitive price) but I believe you will have the most success with Parylene coating as long term reliability looks to be very important as well as flexiblity. Th

Have you talked to people [Specialty Coating Systems 800-356-8260 317-244-1200 scscoatings.com/parylene_equipment/omegameter.aspx] about repairing your Omegameter? Major differences between the testers are: * Ionograph measures conductivity, while t

We regularly strip conformal coating for military customers. Connector removal is not required. The type of coating is the biggest factor. Acrylics and silicones are easy and will come off nicely without any other damage. Epoxy and fully cured polyur

Looks like moisture bubbling out of the board. I doubt that your baking at 60*C for a half hour is going to do very much to dewet the board. 60*C is warm to the touch, that's it!!! Water boils at 100*C. 60*C is the temperature of a cup of Dunkin. Cr

There is too much variation in the different Conformal Coating types and application requirements that you will get many different answers. Your controls will be tailored to the job requirements. My controls for parylene coating aerospace product 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

| Who knows something about the reliability of plasti PEMS and its enhancemant by application of conformal coating (Parylene, metal, SiO2, SiNxOx, etc.) ? We have performed failure analyses on PEM's in our lab for many years. The vast majority of pa
