How to solder small pins

If you're a maker like me who likes to test your ideas out with free samples (Texas InstrumentsMicrochip) then you'll want SMT & SMD soldering as a skill in your arsenal.

I'll be covering David Merrill's guide on soldering small pins, because I believe it's the best strategy with the resources many hobbyists have access too.

The tools I'm using in this demonstration are:
First thing you always need to do when soldering, is to find a open space where there is good airflow and sufficient lighting and of course a power supply for the soldering iron.  Basements are garages are usually good, and a fan can help if the area is on the smaller side.

Gather all your materials, and get settled in your workspace.

A great method for soldering small pins is to pre-solder all the pins on the SMDs and board.

Once soldered, lay the parts down in their respective locations, and join the solder nodes together by gently touching the solder to the pins.

It's as simple as that.  Now just interface your module and see if it gives you a good response!

I'm also going to write up a little guide for using conductive-glue pens, so stay tuned!
