Soldering: The basics

It is time to gather some information to get started with your Arduino! 
There is a nice video explaining the basic rules and providing you with the minimum of understanding on how soldering actually works.

Facts:

• Flux is used to clean the surface to avoid oxides blocking solder to make proper contact
• Most solder wire has a flux core inside
• When solder is applied to soldering iron, the fumes are from the flux core
• Dirt, oxides and overheating are the main causes of joint cracks

Keep in mind:

• Keep it clean: clean the surface and apply flux
• Move your join
• Use the largest tip to provide with enough heat transer
• Rule of THUMB: use slightly smaller tip than your pan you soldering to

Hopefully this post may help!

Good luck!
