I usually solder @ 358°C, 3-4 seconds on the to-be-joined metals, then apply a solder bridge, then solder the other bit to join to the bridge (4-6 seconds total). But according to the datasheet these have a MAX time of 3 seconds with a MAX temp of 260°C. Which means I would probably destroy everyone I soldered using my ‘norm.’ If you’re like me then yes you probably overheated them…
tl;dr: Solder it in under 3 seconds and under 260°C
