I have a question.

I checked datasheet on 28page.

Please tell me the size of the thermal pad shown in red in the figure below

Hello Ozawa,

I do not see any figure, but the land pattern given shows to make the thermal pad large enough for tolerances, so it should be 1.83mm x 1.89mm.

Clint

Clint-san

Thank you for your support.

And I could not attach images. I'm sorry.

Please see the attach picture.

Hello Ozawa-san,

That dimension should be 1.89mm. It actually has the pad dimensions in the datasheet a page or two after that picture.

Clint

Hello

I replied to the customer but the customer was not satisfied.

My customer said,

「Is this the opening dimension of the solder metal mask?」

I want you to see the figure below.

What do you think about the upright part in the middle?

Best regards,

Ozawa

Hello Ozawa,

I cannot see any pictures attached, they are just little "x"s. In any case yes, those are the dimensions of the solder mask opening. See the datasheet section near the end titled "Thermal Pad Mechanical Data".

Clint

By the way, you can request the CAD symbol for this under the "Quality & Packaging" tab on the product page. All the dimensions will be the same as those we use for our EVMs.

Hello Ozawa,

The measurements on page 28 refer to the DAP of the IC with tolerances (min/max).

The measurements on page 29 are for the PCB land pattern which is the max DAP dimension in each direction so that all devices will solder down correctly.

I hope that explains the difference.

Regards,

Clint
