Hi,

This may not be the most appropriate forum but I am hoping somebody can
help or at least steer me in the right direction.

I am looking at plating Electroless Nickel on aluminum blanks that are to
be subsequently plated, machined, and soldered.  I have evaluated several
different types of electroless nickel (hi, mid, low-phos) from several
different suppliers.

I have been told some wildly varying information with regards to the
minimum surface area to be plated required to activate the electroless
nickel bath.  One supplier told me that "surface area to be plated used to
be important, but is less so with some of these newer baths".  One told me
that surface area to be plated did not matter at all.  One told me that I
needed a minimum of 0.5 sq. ft. per gallon to activate the electroless
nickel bath.  I am not really sure who is correct.

Can anybody help?

Thanks in advance.
