Hi,

As discussed, the instructed PCB land pattern for nRF9160 is according to Product Specification:

However, we have noticed that land pattern exceeds nRF9160 dimensions by ~0.5mm in DK (picture and gerber files):

devzone.nordicsemi.com/.../91GerberFootprint.zip

Why extended land pattern is used in DK? Do you recommend this DK land pattern to be used in customer applications?

Br,

JuhaK

Hi Han.

If you look at the Objective Product Specification 10.2, you can find measurements.

You should design using 0.8 x 0.8.

Best regards,

Andreas

Hi Andreas,

As check "nRF160DKschematicandpcbv082.pdf", we can see the layout in pcb format.

But we wants to know the precision size when place in PCB.

Ex, if the pin 103 (VSS) is 0.8 x 0.8 mm in the module, should we design 0.8 x 0.8 in PCB or we should design 0.9 x 0.9 in PCB ? (we think it may have some tolerance when design in the PCB).

Just like below land pattern that show the precision value

Thank you.

BRs, Han

Hi Han.

You can find schematics and layout for nRF9160 on the product page under downloads.
