I’ve got a large inductor that needs to be soldered to my board. The pads are hidden underneath the component so hand soldering is not an option. The data sheet says to reflow at 260c for 40 seconds max.
I did just that with a hot air gun and pre-heating underneath at 180c. I still couldn’t get any flow after a whole minute since the thermal mass is just so huge.
My super wide 2oz copper traces aren’t helping either. How do I solder this part?
