SM320F28335-HT: SM320F28335-HT device that withstands 200 ºC and is RoHS compliant

Juan,

      I have reached out to the Packaging team for answers. Please allow a few days. Thank you for your patience.

Juan,

     I apologize for the long delay in replying. I got the following answers from our packaging expert.

"Yes"

Juan Manuel Fernández Muñoz said:

- Page 179, notes E. If we use ceramic lids instead of metal lids, could the device be RoHS compliant?

"Our Metal lid or ceramic lid, will still be ROHS compliant. This device 320C50GFAM50CS is currently using metal lid"

Hi Hareesh,

The P/N you mention in the above reply is not the one that I pointed out previously. Just to clarify, can the P/N SM320F28335GBS be RoHS compliant if we select gold-plated pins and any lid?

On the product page, if I go to "Ordering & quality" and click on the column "Quality, reliability & packaging information" for the P/N SM320F28335GBS (https://www.ti.com/quality-reliability-packaging-download/report?opn=SM320F28335GBS) it specifies that it is not RoHS compliant. Is it possible to obtain an offcial document from TI clarifying that the above option is RoHS compliant?

regarding the other P/N SM320F28335KGDS1, mentioned in the first message, could you please answer the questions?

Thanks.

Juan,

            I am aware your part is SM320F28335GBS. I think my colleague only quoted 320C50GFAM50CS as an example for a device that is using metal lid.

I need to check on this with the packaging team.

Hi Hareesh,

Any news with the official confirmation of the RoHS option of the P/N SM320F28335GBS?

Any news with the technical information about the P/N SM320F28335KGDS1?

Thanks.

Juan,

    I think your questions about gold-plated pins and ceramic lid has already been answered. The  information that needs to be provided to you are:

Official document.

Drawings of the die.

Is the above correct?

Yes, it is correct.

You only plan to buy the bare die from us. The die itself is RoHS compatible. You mentioned you intend to employ a subcontractor to encapsulate it. An official document certifying RoHS compliance should then come from the subcontractor, not us.

Juan Manuel Fernández Muñoz said:

I can't find the drawings of the die version. In the datasheet I have only found the drawings for the ceramic and HLQFP versions.

The information you need is in pages 19-25 of the datasheet.

We plan to acquire SM320F28335GBS if it is RoHS compliant, so we need the official confirmation of the gold-plated pins option.

If the above option is not RoHS compliant, we will plan to acquire the die. In parallel we are in contact with a subcontractor, and he has told us that the information in the datasheet is not sufficient to desing the packaging, so we need addtional information about the die for this design.

Juan,

            I was under the impression that you were asking for a document for the KGD version. I think I understand your requirement correctly now: 

For the GBS package, you want a document from TI that Gold-plated pins and ceramic lid qualifies for RoHS. Is this correct?

Juan Manuel Fernández Muñoz said:

What we have in the datasheet is all we have. Can you please check with the subcon what information is missing?

Yes, it is correct.

Hareesh Janakiraman said:

"Our Metal lid or ceramic lid, will still be ROHS compliant. This device 320C50GFAM50CS is currently using metal lid"

If both options (metal lid and ceramic lid) are mentioned in the document, the better.

Hareesh Janakiraman said:

OK, we will translate it to our subcontractor.

Thanks.

Juan,

    I will explore about the document.
