Here is some feedback I got regarding de-soldering: You may remove the SIP with an under-heater and then an airgun. This works well but the pads can come loose if you try to lift the device too soon before all the solder has flowed properly.

I will let you know if I find more information regarding de-soldering.

Have you checked with your manufacturing/prototyping company?

If you like, you may start with this design.

Hi Seth,

Yes, modifying the board so that pin 104-127 are floating would be a safe place to start. The pins have various properties and some of them certainly should not be grounded.

In any case. Please be aware that Nordic is offering free hardware design reviews. If you upload schematics and PCB design files we could review the part of the design that is related to the Nordic parts.

Best regards,

Håkon
