Part Number: LM2904

Dear Sir,
Hello, I am Lee Yeong eun of ITM Semiconductor.
We use LM2904DGKR product through vendor, and we have been informed that Bond Wire uses two materials: Gold and Copper.
When you do'Material content search' on the TI website, different'Component Information' is provided depending on the wire.
Is it correct to use both gold and copper for the bond wire?
And if you use both, how should you use Component Information?

Hello Lee,

I'd like to know a little bit more to better answer your question. What is your main concern with the type of bond wire being used?

Best,
Jerry

Once the material composition is registered in the customer's system, it cannot be changed, so it is necessary to check the type of bond wire. (The supplier said that the LM2904DGKR model uses both gold and copper)
If Bond Wire is registered as Gold, the report must also be submitted for Gold.

Hello,

Both gold and copper can be used, so I would submit reports for both copper and gold.

Best,
Jerry

Dear sir,

Copper and gold are not simultaneously written in the material composition table, and a material composition table including copper wire and a material composition table including gold wire are separately provided.

If it's a material that uses both, is there a reason why we provide a material composition table separately for each wire instead of marking it at once?

Thank you for your response.

Lee,

Parts do not use both copper and gold simultaneously, however there are some devices of that part number that use copper and some that use gold bond wires. The material composition table is provided separately because there are two different possible material compositions.

Best,
Jerry
