MarkT:
OK, I'll rephrase my question: how are you going to solder that and have it exactly level and aligned on the circuit board so that the X, Y, Z axes are aligned to the board?[edit: and if you can, show us how you do it!]
For now, i'm not worrying how exactly It would be aligned to the circuit board. I just want to solder it with whatever I could and connect it to my Arduino Uno. If necessary I would just solder it to some wires and not worry about sticking it on a board at all. If i'm going to build a project later on, then i'll consider your question once again.
