CC3220MOD: STICKER LABEL AND PRESSURE ON THE MODULE

YOUNG LIN

Part Number: CC3220MOD

Hi,

We are using the CC3220MOD for the laboratory test devices, just some questions related with the metal case on the CC3220MODSF module:

1. Can we put a sticker label (no conductive) on the surface of the module? I suppose it will not impact on the Wi-Fi performance of the device, as the Wi-Fi antenna is out of the module.

2. How much pressure can support this metal case ? Because our device will be encapsulated (potting), sometimes the potting material like epoxy can produce pressure on the board.

Thanks and Regards,

    Hi,

    I think own label on module will not be issue.

    But potting / conformal coating of the module is not recommended. It can ingress into module and damage them. From CC3220MOD datasheet:

    TI does not recommend the use of conformal coating or similar material on the SimpleLink™ module.
    This coating can lead to localized stress on the solder connections inside the module and impact the
    module reliability. Use caution during the module assembly process to the final PCB to avoid the
    presence of foreign material inside the module.

    Hi Yong Zha,

    What will be on the sticker? Can you share a picture of it? 

    Yes, the sticker will not impact the Wi-FI performance.

    Hi Seong,

    I don't have the sticker picture (we are just planning it now), it will be used to indicate the lot number, an ID of the device.

    Thanks and regards,

    Yong Zha,

    What about the certification IDs? Will these be visible on the sticker?

    Which region's certification will you be leveraging?

    BR,
