This is third part of the class "Working with SMD components at home", given for the Vienna Wireless Society ham club.
During this lecture I will show how to use some of the techniques mentioned in second lecture to build a small power RF amplifier using MMIC.
I will explain how to prepare board for placing the components, then show how to place them and, finally, how to solder the board using hot air reflow process, and how to use board preheater. I will also explain why reflowing electrolytic capacitors or other sensitive components can be dangerous for them.
