https://devzone.nordicsemi.com/f/nordic-q-a/18753/nrf52832-footprint-designHi - I am designing some boards using the NRF52832 and would like to check a couple of things about footprint design. Unfortunately I don&#39;t have access to Altium, and am therefore dependent on the pdfs of your reference design. the large grounden-USTelligent Community 13Wed, 04 Jan 2017 12:58:27 GMThttps://devzone.nordicsemi.com/thread/72407?ContentTypeID=1Wed, 04 Jan 2017 12:58:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dbc77fb2-15c4-46d3-8217-6cfa67426501Gavin<p>Many thanks for the quick response - v helpful</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/72406?ContentTypeID=1Wed, 04 Jan 2017 12:54:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0978dd13-83f0-4498-a019-c9d7770a9198Hung Bui<p>Update on 2) If you are talking about the bottom layer then tenting is good.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/72405?ContentTypeID=1Wed, 04 Jan 2017 12:36:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1c06a1c9-2c64-4d78-8b33-d8a71a312442Hung Bui<p>Hi Gavin,</p> <p>You can use the Altium Designer Viewer, it&#39;s free.<br /> Or you can use any Gebber viewer to open the Gerber files.</p> <p>When you open using Altium, you can see the hole go through top layer (how could it be not if it&#39;s 2 layers PCB ?) I will check with my coworker to see why we have a solid pane in the pdf.</p> <ol start="2"> <li>I don&#39;t think tenting needed.The pad acts as GND contact and heat sink.</li> </ol><div style="clear:both;"></div>
