So you have bought a QFN package chip - any idea how you are going to solder that?  (Or is it on a breakout board?)


Don't worry, I have hands plus a solder station ;)

Thanks for the advise thought, really appreciate it man!

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. :)

With a glue gun: drop some hot glue on the board and then push the chip's topside onto it. And solder from the bottom side (now exposed).

Also, you don't need it to be "exactly" level. Just reasonably level would do.

O! really? Can a glue gun glue actually conduct electricity and work as a "soldering" material?
