	''I built ten boards. Four did not work originally. Three were solder issues with the PT4115. I fixed these by using a cue tip to add flux to both the PT4115 and solder wick and using a clean tip draw excess solder off the PT4115. They looked fine but this worked on three of the problem boards. On the fourth board I powered it on and then using a jumper cable started working backwards from the led. Turned out that I had a cold solder joint on the ~~zener~~ diode. Re-flowing from the bottom of the board did not fix it. I had to do a re-flow from the top.''		''I built ten boards.

			The trick to soldering these little fellows are to:<br>
			1. Use some liquid flux on the pads<br>
			2. Use a fine, clean, tip on your soldering iron<br>
			3. Use VERY LITTLE SOLDER ! A fine gauge solder would be helpful<br>
			You should concentrate on tacking down one of the the outermost pads (not the center pad) to hold the IC in place.<br>
			Once you do this, the rest will be much easier.<br><br>
