depends on the type of solder but yeah, I’m not exactly holding it there tho. just high airflow at that temp for a few seconds to push the rosin underneath the chips. helps a lot with bga chips where water can actually get underneath the chip and short connections or leave debris even once evaporated. for actually reworking chips I use around 480c.
depends on the job. shitty jobs I won’t give two weeks especially if there’s already animosity from management (which has lead to some pretty entertaining quitting stories). most I’ll do for something like that is ask my coworkers if they think they can get by without me (assuming I also liked the coworkers).
if it’s a job I liked, I typically give notice via email and then go and bring it up in person to the recipient as well.
