Heating & Applying Solder

Hi, this is Jeff Naylor from Mtroniks in Mesa, Arizona for Expert Village. In this section, we're going to be demonstrating proper heating techniques and to illustrate my points; I'm going to be soldering this resistor on to this circuit board. Proper temperature is important for a consistent join. With a 64 solder, I set my iron for 700 degrees Fahrenheit. This temperature is hot enough to evenly heat the solder but not too hot as to destroy electronic components in circuit board pads. For our first practice, I'm using a circuit board and a resistor. This side of the circuit board has all of the artwork on it but none of the electronic traces. On the other side we can see where our two component legs come out and this is where we'll be applying solder. Now instead of actually touching my iron to the solder, I'm going to heat this surface I wish to apply to the solder to. In this case, it?s this pad and this wire. So I'll wedge my soldering iron tip between the two. Now just to start the heat conduction, I will tap it with a little touch of solder. Now I will go around the backside and start building up solder. Now we heat the solder until you see the impurities in the surface bubbling up. Once the impurities have boiled off, this solder has become hot enough to provide a strong joint. You can see that this is a good, strong joint because it?s nice and shiny and even all the way around. Now before returning the iron to the holder, you scrape off any impurities, tap it and return.
