Hello again group and I want to thank you for helping me with past
questions. I have another question regarding the thickness of gold that
should be applied to PCBA pads. We have standard gold over
nickel/copper pads. The pads are not used for any insertion but used as
a contact point for board interconnection via a zebra strip.
What is a recommended gold thickness over nickel to prevent nickel
oxidation caused by migrating nickel?
Thank you for your help again.
Thanks
David Harman
