PCB FINISH FOR HIGH PIN COUNT SAC ALLOY BGA | 3 June, 2016

I am planning to attach 1760 pin BGA. The pitch is 1mm and Balls are SAC alloy type. The PCB is for aerospace use and expected to work in harsh environment.

What is the recommended PCB surface finish and the attachment process for such a application.
