It is a good idea to clean the PCB before you start soldering
An easy way of soldering smd components is to pre-tin one pad first. Then position the component by melting the pre-tinned pad and placing the component on its footprint. Then continue to solder the other end. Using extra flux will help a lot.
When soldering the LEDs to the board you must start with the upper most one.
the cathode (negative) must be on the outer most pad
starting clockwise, we will add all the other LEDs. The next LED must have its anode (positive) pad pointing outward.
Continue to alternate the polarity of the LEDs until you have soldered all 8.
You can figure out the polarity of your SMD LED here http://www.niktronixonline.com/Articles.asp?ID=140 . Another easy way of checking is to use the diode tester on a multimeter.
add the 18 or 22 ohm resistors in the positions shown below
add the final 10k/12k resistor
solder on the chip with the notch pointing to the right
Finally solder the battery clip on the backside
and it should light up!
