LMH6881: WQFN package questions about packaging (leads and resin molds) follow-up

FRANK1

Part Number: LMH6881

Hi Team,

is there any package engineer or product line engineer can help me on this customer query?

The customer has been asking and I can not get response from QEM.

Please check this URL.

Is LMH6881SQ/NOPB 3.4.1, 3.4.2 or 3.4.3?
I think it's 3.4.1.
The LMH6881SQ/NOPB I have looks like the figure in 3.4.1.
I would like to confirm whether there is a possibility that it will be like 3.4.2 due to manufacturing variations.
The attached email you received seems to be discussing 3.4.3, is it different?

Hello Frank,

The LMH6881SQ/NOPB has a flat leadless package with an exposed thermal pad which is internally bonded to the ground pins. Here are some additional resources on the package: link1 and link2.

I will have to talk to a packaging expert on the specifics with regards to molds and get back to you as soon as I receive an update.

Thank you,

Sima
