Hi all,
I hope one of you may be able to help with this ... and that I have posted in the right sub-forum ...
As it is I have for some time now been searching for a very high purity copper electroplating process for high electrical conductivity, and have now ended up preferring Heimerle-Meule's 501 bright copper plating solution because it should be possible to achieve 99.5 - 99.9% copper plating purity.
However, in their application datasheet (pdf attached) they specify the use of Cu-P anodes (Cu-P ~ (0.04–0.06% P)) but these appear to be quite difficult to find![[ponder]](/data/assets/smilies/ponder.gif "[ponder] [ponder]")
... Google searches don't give any hits for such a copper alloy .. What I can find though is Cu-DHP anodes which have from 0.015% to 0.04% P content (99.9% Cu). The difference is not huge yet I don't know if it may be significant - might one of you know if the Cu-DHP for these "practical purposes" will be the same as Cu-P?
Thanks for any insights - also if you have a suggestion for an even higher purity copper plating solution (in a small scale - for trials).
Cheers![[wink]](/data/assets/smilies/wink.gif "[wink] [wink]")
