Okay so I have this microboost, I got it in a host from moh that was setup for a 445, it was already thermally adhered to a little aluminum heatsink. It was having problems overheating at 1.3A even on the heatsink, causing the laser to actually pulse slowly, then very quickly as it heated up.

So I tried to get it apart and this is what I came up with.

there is alot of thermal adhesive still on it, and the thing that looks like a little spool with wire wound around it, the top kinda chipped.
My question is, is this still useable, and also, how would you guys go about getting that thermal crap off? It's on there pretty good.

It's useable with the chip in the top cover on the inductor. I have a micro-boost that's missing the whole top cover, and it works just fine.

Thermal crap I have no idea, but if you can get to the pot you don't need it all off.

yeah. It's just set to the highest range, and can't change it because of all the thermal crap, was wanting it to be like 500mA but the lowest in the range im at is ~600

Also thanks, I didn't figure it would affect it if the top was chipped.

dude I'm such an idiot. I thought that the solder points were on the back, opposite of the pot, like on a flexdrive. But there on the front, the same side as the pot, so I can get to them and change the range position haha.

Yep, i was just gonna say bhwollen, it's all yours if you want it. It works fine, you just have to unsolder the resistor to get to the lower range which will let you get 500mA out of it.

I can't desolder worth crap. I have desoldering wick, and have never been able to get it to soak up the solder. I must be doing it wrong.

I have the exact same problem! The wick ends up getting stuck to the damn thing I'm trying to desolder. And plus my soldering iron's tip just broke and now all i have is a big knob. :(

EXACTLY, that is exactly exactly exactly what happens to me every single time! I broke my tip too and had to go get a new one yesterday.

I'm going to work now, pm me if you still want the driver, maybe one of us will invest in a desoldering iron/solder sucker

If you can up your iron temp. Another trick is place your wick and get a ball on your iron tip and place on the wick. that heats up the wick and underlying pad for easy solder removal.
