nRF52840 Lead Finish of the BGA Balls

John

We are having a very difficult time soldering the nRF52840 to the PCB. Our Operations Department is asking what the lead finish of the BGA balls is. Would be great to get on the phone with you guys to discuss all the things we have tried. You might have some ideas. Thank you!

    I'd like to bring our FW engineer into this discussion but I don't see how I can add him. I'll try converting this to a public question. By the way, we have tried the internal LDO and DC-DC 1 and we get the same failure rate.
