LOL, I'm not sure I do either, haha, but I'm figuring it out
And you're right, with a good soldering iron, it is very easy to solder these boards up. This is how the Real Time Clock and ITDB02 MEGA shield comes comes:
and this is what it looks like after about 3 hours of soldering:
Actually it wouldn't have taken 3 hours except, see that tiny little chip to the left of the teeny little silver cylinder? I soldered it on backwards and had to unsolder it (much more difficult than it sounds) clean up all the solder pads and re-do it. I actually don't know if there is a right way or wrong way to put it on, but there is a teeny weeny little dimple on one corner and one of the photo's I found on the net of another guy who built the same thing had the dimple in the opposite corner that I did. Logically I just assumed I was the one between us that got it wrong
And the back:
