"Copper Oxidation Level"

-----

2003

I am involved in Plastic Semiconductor packaging. I am currently working on a project to define the level of oxidation on copper leadframe. Do you have any advice on how to classify the level of oxidation?

Same question as letter 22189. How can I define the level of oxidation on copper leadframe after Die Attach Cure and before molding. Any advice to minimize this.

Weighing the part before and after is the traditional way of measuring oxidation level.
