Topic: Copper plated pillars are looking dome shaped instead flat

Hi All,

My copper plating process is giving me dome shaped pillars instead of a flat shape. Does anyone saw this before? Pillars are 15um tall and 30um in diameter. Please advise me if anyone knows any quick fix for this. Bath is analysed regularly and all the additives are in right proportion.

Thanks and Happy new year,

Without seeing a picture, I would venture to say that you have some contamination in the tank. Check that your filters are running, and maybe change the filter media while you are at it.

If what I am thinking of is true, you may want to search on the term "Treeing" and see if any pictures you find are similar to what you have.

Hope this helps!

I'm not sure if this is the right pic or not - but I found this on the string.
