Step 4Practice Soldering!

I'd say this is VERY IMPORTANT unless you do a bunch of small surface mount soldering. The last thing you want to do is fry your new unit. If you are anything like me you have a bunch of old boards hanging around to practice on. I found a chip that looked similer and did a bunch of practice runs to get down my technique.

I used a cold heat soldering tool. It actually worked very well which suprised me. I never used it directly on the point of solder but rather used it to heat the resistor wire well away from the point of contact. Cold heat is neat but you need to be careful to not ever burn out your electronics by shorting the two halves of tool's tip through your board. Heating the resistor wire away from the soldering point lessens your risk of this happening.
