RAK3172 PCB land pattern recommendation missing total pad length dimension

Hello-

I’m creating a PCB footprint for the RAK3172. During this effort, I realized the datasheet fails to show the complete footprint dimension for the recommended pads.

I can see the width of each pad is recommended to be 0.7mm. I can also see each pad should extend 0.8mm beyond the package dimension. But the “total” pad length can NOT be determined with the given layout drawings.

I need to know how long you recommend the pad should be under the package (or the total length of the pad).

Thanks!

Hi @loradev54 , I will ask the hardware team about it. I’ll get back to you asap.
