Hi,

I have very successfully used Corona Discharge, a non vacuum form or 
plasma, to clean parts and improve adhesive adhesion.
It creates a fair amount of Ozone while running.

Rich,
as far as I know UV-Ozone is not capable to remove inorganic 
contaminations. Plasma on the other hand can remove both, organic and 
inorganic residues...

Betreff: [TN] UV-Ozone Cleaning Processes

Are any of you familiar with UV-Ozone cleaning processes?  I am 
considering using Plasma to clean some PCA's prior to coating to improve 
wetting of coatings, but now wonder if I should also consider UV-Ozone.



Anyone care to state some pros and cons of each for my application?



Suprisingly enough, I don't see any mention of UV-Ozone cleaning in the 
IPC -CH65B handbook.



Thanks
