Hi team,

I'd like to know about PCN(0240624000.0).
Is this a device marking change?

Hi! For PCN20240624000.0, the original device marking remains the same. The symbolization maintained the current Year/Month binary codes. The 4 additional binary codes are for internal use only for easier traceability.

Hi,

Thank you for your reply.
Do you have before and after marking photos of the changes?

You can refer to the illustration below. The blue dashes are what we refer to as additional binary code. This is on the PCN.

Hi Lorena,

I checked the sample I had and could not find how to read the code.
Please let me know what these numbers indicate and what changes will be made in the future.

Hi! This R2C top mark is not for TL41. Please double check.

Thank you for reply.

I couldn't understand yet.

Are you saying that the device markings will remain the same, still R2C?

If so, please elaborate on what this PCN will change.
If device marking, where is the marking?

BR,
Kengo.

Hi Kengo, the device id on the top mark will not change; it will remain R2C. Kindly review the PCN again. It describes in detail the change.

Hi Lorena,

OK, I understood the top marking not change.
However, I have looked at the PCN and do not know what will change.
Could you tell me more detail?
Is the label information changing?

Hi Kengo, when you start receiving units from the TIPI assembly site, you will see the binary code dashes (black color on the illustration) on top and below the R2C. Moreover, there will be an additional binary code (blue on the PCN illustration).

Hi Lorena,

I'm very confused by your comments.
Do you mean that the following changes will be made?

In other words, it will be added to the markings?

Hi Kengo,

This is an example but for a different device. You can see the dashes above and below the top mark. Hope this helps.
