Hi

In 3310 D/S, title is LQFN but p.26 package is LGA.

And in SUGGESTED PCB LAYOUT TOP VIEW, expose pad footprint don't have size information.

How long these PCB are ?

Best regards

Thank you very much.

Hello, the recommended center pad should match the EPAD of the part, 1.5mm x 1.5mm. We should add that dimension to the drawing. Thanks for pointing that out.

Hi Marty M, I'm an FAE closely working to the questioner. He's essentially asking if '1.5mm x 1.5mm' part mentioned in your answer was just a typo, which contradicts to what you say at first place. Just double checking.
