Black Oxidation Technical Inquiry


(2000)

1. I'm interested to know about black oxidation properties, chemical & physical.
2. How is black oxidation prepared/processed.
3. Is black oxidation compatible w/ Palladium plating? bare Cu?
4. Is it reactive/resistant to etching chemicals?
5. Does it react in contact w/ NO CLEAN flux.
6. What is the maximum temperature that it can withstand?
7. How is it applied?
Reason for the inquiry: I belong to the R&D group of Fairchild and we are developing parts that will/may need this process for improved product performance. I'd be happy if you can post a reply to this letter.

It would help if you would tell us what type of black oxide you need, i.e., what substrate and application do you have in mind.

I plan to apply the black oxide on a Ni/Pd plated leadframe. This will be for power application. Honestly, I don't have any idea on the different types of black oxide but what I'm looking for is something that would meet my initial requirements. This will be for high temp applications. I plan to use this as a solder dam.
