sometimes stuff like that will melt parts and burn soldermask before actually reflowing your tiny part
because what is its like, 0402 on ground plane
next to it is like, relay or connector
with only small signal traces attached, no shield
without a tip to focus, youll melt the relay and connector way before the ground plane heats up enough to solder the smd
