https://devzone.nordicsemi.com/f/nordic-q-a/118601/nrf5340-hardware-stackup-e-g-pca10143I am looking for an example 6 layer stackup for the use of the nRF5340 / nRF7002 combo that has been proven producible by pcb manufacturs. The nRF5340-QKAA requires microvias in the second row to go to a lower layer for fanout.

Microvias are always blind, so you have these from layer 1 to layer 2 only for the fan out of the inner row of pads. Else, there are no additional complication by adding more layers to the PCB.&nbsp;</p> <p>Here&#39;s the stackup for PCA10143:&nbsp;</p> <p><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1738762872231v1.png" alt=" " /></p><div style="clear:both;"></div>
