Dear Ilan,
Could you explain more on your question? I don’t know the exact meaning of “plating materials”.
It’s kind of “reflow condition”? ![:question:](https://emoji.discourse-cdn.com/twitter/question.png?v=12)
Thanks,

Hello,

I need to know what chemical elements composes the plating of the pins, so it can be determined how should it be soldered in a leaded environment
Thanks
