>but maybe you should get a practice board first, if only to get more confidence
No other boards... I'll have to 'do it live'.

>start by taking the other chip off. dont bother practicing unless you have a second identical board lying around, since every board is different and the board itself is the thing most likely to break. you can rip pads/traces off the board if youre too quick/forceful.
yeah, thats what I thought.
>turn the hot air up to max speed. temp is whatever, i think mine is set to 600 F. heat up the chip by waving the wand in little circles around the pads. keep the nozzle close to the
use the new chip to practice handling it with the tweezers, some chips can be deceivingly difficult to pick up with tweezers.
Great advice! I'll def take it slow and I'll plan ahead.
>you can protect stuff with Kapton/copper/aluminum tape if you want, but theres nothing in your original pic that i would be super concerned about (those two metal things are crystal oscillators, btw; exercise caution if youre planning to ultersonic the board afterwards). post a pic of the other side of the board if you can. also it doesnt have to be tape, you can use anything that can withstand the heat and will block airflow.
My DAC is slightly different than the original pic which was taken off the web.
Luckily, the chip is the same.
However, it's way more complicated. Lots of caps around too.
Not sure how to protect all this shit.
Anyway, here's top and bottom of the board.

I don't have an ultrasonic. I have a brush and a bottle of IPA tho.

I'll be doing it tomorrow. I feel tired af and my self-confidence level is at near zero.

I appreciate any advice between now and tomorrow evening!
