MSP430F5419A: About Markings of ZCA (nFGBA) package

O.H

Part Number: MSP430F5419A


Hi experts,

Q1:Where can I find Markings information about ZCA(nFGBA) package of MSP430F5419A?

Q2:Also, is it correct to assume that the "A1 Coner"(Pin1 Location) on the ZCA(nFGBA) package is the same as the white circle on the ZQW113?
(The silk on the device surface is slightly different, but otherwise the same?)

My customer is currently writing a specification document for a product with MSP430F5419A and needs accurate markings information. But in the MSP430F5419A Device Erratasheet (Rev. AC), only ZQW113 and PZ100 are listed. So, the best solution would be to provide the information as a document. 

We apologize for rushing you, but my customer are in a hurry and we would appreciate it if you could respond to Q2 by July 30.

Best reards,
O.H

    Hello,

    The ZCA (nFGBA) package marking details can be found in the datasheet (page 110 to 111) or the ZCA package overview. Looking at the ZQW113 package overview, it seems to have an A1 Corner as well. Both should have a white circle in that location.

    Hello,

    Thank you for your quick answer.

    I now understand that there is a white circle in A1 CORNER for ZCA as well.

    By the way, do you have any plans to modify the erratasheet?

    It is expected that formal Marking(silk) information such as erratasheets will be required as documentation. It would be great if you could tell us if there are any plans to add this information.

    Best regards,
    O.H

    Since the above answer did not satisfy the customer, I am sorry, but I would like to confirm a few more things.

    Is the white circle mark on the ZCA package REALLY located at the "BALL A1 CORNER" as shown below?

    The customer has checked the ZCA package overview, but can't be sure because there are no markings specific to the package. Thank you for requesting the update. However, we would appreciate it if you could share the definitive information as a manufacturer, even if it is a tentative version.

    Best regards,
    O.H

    Hello,

    I've dug deeper into this topic. The package markings in the erratasheet indicate where the 1-pin is located on the package with respect to the text (e.g. part number, lot trace). The actual marking may be a white dot, concave indent or shaded area depending on the type of package.

    The ZQW113 package overview is your best resource to know what the package marking for the 1-pin will look like - a shaded area in this case rather than a white circle. I've ordered a ZCA sample to check for myself, but it may take longer than a week for me to receive it.

    Hello,

    Thanks for the reply.

    I got an actual photo of the surface of the device package from a customer. For convenience, I can't post the actual product, but the ZCA package had the text printed on it as shown below. (Both the ZCA package and the ZQW113 package had no shaded area and a white circle.)

    Is it correct to assume that the "BALL A1 CORNER" in the ZCA package overview is definitely located at the white circle in the above figure?

    Please let us know if we need to wait until you get a sample yourself in order to get definitive proof.

    Best regards,
    O.H

    Thanks for sharing these details. It looks like my earlier assumption was correct. Thus, it appears that the shaded area in the ZQW113 package overview indicates where the 1-pin marking will be located on the package. In this case, the marking is a white circle.

    Yes. If they have access to a physical device in the ZCA package, then the customer can confirm this themselves by looking underneath the device on the corner where the 1-pin marking is located. There, they will find the C3 pin (asymmetrical compared to all the other pins) which indicates where A1 is located. The following diagram comes from Figure 7-3 in the datasheet.

    You do not need to wait on me. If the sample varies from what the customer described, I will reach out to you.

    Sorry. We missed that we can also determine by checking the C3. The above answer has satisfied our customer. If there is any mistake, please let us know and we will do our best to fix it.

    Thank you very much for your kind support.
