Hi,

I am trying to get NiP pattern with plating. Anyone have relevant experience?
Some papers reported that the bath's pH value should be around 3-5. The as
obtained bathes have pH near 0-1wether you use H3PO4 or NaH2PO3. The normal way
to get this value is add NaOH but I found it is quite hard to handle it since
NaOH reacts with Ni2SO4 and the product is not easy-solving in water?

Any comments and suggestions are apreciated.

Thanks!

Zhang
