If there are no such standards, and this application is indoors in a relatively benign environment, then 5 µm (0.0002") minimum would be a good place to start because that's pretty much the commercial minimum. I am familiar with plating but not with IEEE [link is to specs at TechStreet] or NEMA [link is to specs at TechStreet] or other standards that might dictate plating thickness for this particular application. letter 122/11.

Have you considered the thickness on this part also? currently our plating thickness is Fe/Zn 12.5 microns and for cost effectiveness shall I reduce it to Fe/Zn 8. new LazyLoad({ elements_selector: "iframe" A.
