SM320F2812: SM320F2812GHHMEP

Page 154 of the datasheet (www.ti.com/lit/SGUS051) shows the lead/ball finish to be SnPb. I presume you are asking about the composition of the ball. I need to reach out to our packaging team. Please give me a few days.

thank you.

This type of information can be generally found at  https://www.ti.com/materialcontent/en/search?partType=tiPartNumber&partNumber=SM320F28335.  However, I am unable to pull the information for this part #. I am researching why. Can you tell me when you bought these devices? You can respond to me by private message, if you wish to do so.

we purchased this item from a broker.

At XRF test the lab found balls composition of 47% Cu, 20% Sn, 20% Pb.

Im trying to understand if this is typical for this devise or whether im supposed to see composition of 63/37 as a leaded part?...

Hi Iris, one other comment, the substrate/tape that the ball is connected to does contain Cu which may be why that was found in your XRF test.

is it reasonable to find 47% of Cu?...

thank you very much.

can you please share with me the source of the composition ?
