Well, here in Tulsa, we're just like a lot of other people in the country this morning, trying to stay warm. Right now we're sitting at -10 C. with a wind chill of -15 C. It's supposed to be colder tomorrow... GA, I have your pictures posted now.

Hi All experts, Testing (combine test of 16G at 85 oC) was performed on evaluation boards with under-filled BGAs. Open issue (cracks) was detected only at some corners of the BGA (35x35mm with 1156 balls) after the test. Lead-free process and PCB with ENIG surface finish. Peak temperature is 248 oC with a 65 sec above 217 oC. FYI, the service lab has not come out a report. What are the possible causes? (CET mismatches, Lead-free alloy related, material, processes) Thank you in advance.
