Tool/software:
The description in your data sheet is: Creramic quad flatpack with flat leads brazed to non-conductive tie bar, Hermetically sealed with metal lid, leads are gold plated
I need to know the materials used.
What alloy are the leads made of?
Is there a nickel underplate under the gold plate on the leads?
What alloy is the lid made of?
Is the lid plated?
What alloy is used as a seam sealer between the lid and package?
What braze alloy is used between the leads and tie bar?
Thank you!
