I guess that I need to reword this a little differently. I know that the
oxide peel strengths are different from the old sodium brown and blacks
compared to the oxide replace chemistries, but what I was looking for was if
people see a difference in peel strength between suppliers of alternative
oxides given the same copper weights and material types.
Thanks

We see peel strengths higher than that of black oxide - 2x over
non-reduced and 30% over reduced.

I have been asked by a colleague to find out what PCB manufacturers have
been getting for peel strengths from the various alternative oxides
suppliers. I think that the numbers are very close, much like the old
sodium browns and blacks but I would be interested to see if people are
seeing a difference. It might be better to reply directly to my email
address as I do not want to start a vendor up roar on the subject.
Thanks in advance
