Refer to the figure below for identification of the individual PCB parts. 

 

 

 
 

 

On all the mechanical assembly soldering you do, you will use the same technique. You 
tack a single tiny point first, and then check to see that it is square and aligned with the 
registration points. It is easy to re-heat the joint and adjust the alignment when there is 
only a single point. Then you tack the other pads, before you do the finish soldering.
