Could you please confirm whether Pin-1 orientation .

Hi rahul1998,

Thanks for reaching out!

The round indicator in the footprint indicates the 1st pad of the component/physical package. For this BGA component, it is pad/ball A1.

Feel free to let me know if you have further questions or concerns and we're here to assist.

During cam scanning for production, It creates error and manufacturer asking the footprint pin 1 alignment is different or mismatch pin 1 alignment .how to resolve it,If the footprint is okay???

Thanks for sharing more information Rahul!

The pin indicator, in general, always points out to the first pad of the package/component. It is possible there's a different cause of the error.

We checked this further and it seems like there was a discrepancy when the footprint was created. The datasheet shows the bottom view of the pinout which led to having a mirrored footprint. This might be the cause why you're seeing an alignment error.

Our team will work on updating this part asap and we'll get back to you. Thank you for your patience!

The footprint available in your library was used in good faith, assuming it had already been verified. Now you are confirming that the footprint itself may have been created incorrectly due to the bottom-view interpretation, which is quite concerning.

This is not a minor issue, as an incorrect BGA footprint can result in PCB assembly failures and significant rework costs.

Please treat this as a high-priority issue and provide the corrected footprint along with an explanation of the exact changes made, so that we can verify our design before proceeding with manufacturing.

Thanks for sending your honest feedback, Rahul!

We completely understand the frustration. This a legacy part created a few years ago and rest assured we have strengthened and improved our verification process since then.

The team is currently working on this part and we'll get back to you shortly.

Hi Rahul,

We dug deeper on this part number TXS0102YZTR and it seems like it is already obsolete in the distributor's site and it is no longer represented in the current datasheet from Texas Instruments. We will be removing the part page for this as well.

However, please feel free to download the similar part, TXS0102YZPR here: https://www.snapeda.com/parts/TXS0102YZPR/Texas%20Instruments/view-part/

The symbol was improved and the footprint has been updated according to IPC-7351B. The entire library has been verified as well.

Please feel free to let me know if you need anything else and we're here to help!

Sincerely,
Vik
