LM224: LM224DRG3 Performance problem

Emily li

Part Number: LM224

We purchased this product from TIstore, and found dirt on the product after delivery, which looked like water stains or oil stains
Could you please help to confirm what causes it, what marks it is, and whether it will affect the performance and use
thank you

Hi Emily,

Welcome to E2E! :)

Could you provide the topside image for the suspect parts and the TI reel label? How many devices do you see this on?

Thank you!
Best Regards,
Ashley

Hi Emily,

Our Assembly site has commented the following:

If the stain is only observed on the package bottom side, it is most likely a cosmetic defect and not impact functionality. The only possible concern would be if this appears to be on the leads and impact solderability.
They have not seen or been reported this type of stain, so the source is unknown at this time without understanding the composition of the stains.

Please let me know if you have further questions.
Thank you!

Best Regards,
Ashley
