Spec on component says use solder which does not scavenge gold such as Indalloy #2, or conductive epoxy or low temp solder preform. Also says cannot withstand 200 C for more than 10 seconds.

Preforms, as well as Sipad are also Sn-Pb. I have no experience with conductive epoxies, but know that they are not as good as solder from a reliability perspective.
