Here are the instructions from some other kits: Install surface-mount inductor L3. Pre-tin the inductor pads on the PC board sparingly with solder before installing the part. Place this component on the two pad locations and restrain carefully in place with tweezers. Tack one end down with the soldering iron, solder the other end sparingly, and retouch the end originally tacked down. Good component alignment is important to ensure that there are no short-circuits- check your work carefully for solder bridges.
U1 Installation: It's important to install the Surface-mount IC (U1) first- it's more difficult to install when surrounded by other components. Remove U1 from its protective packaging and place it over the pads on the board. Do not pre-tin the pads. 'Tack' down one of the IC corner pins while holding the device down with a fingertip. Move to the opposite side of the IC and solder all pins down. Note: it's easiest to use an excess of solder and remove the excess with solder-wick. (Solder the second group of 4 pins and wick as needed. I have built both kits and had no problems. I didn't use solder wick on the 8 pin U1 chip, just careful use of a narrow chisel soldering iron tip and thin solder. I use a temperature controlled, ESD safe soldering station.
