Hi, this is Jeff Naylor from Mtroniks is Mesa, Arizona for Expert Village. So now we've soldered
a resistor on a circuit board and that was fun, but let's say we have a broken component
we need to remove. If you have defective parts you need to remove from a circuit board, you
will need to remove the solder from the joint. There are two basic ways of doing this. You
can use a solder wick which is a braided fiber. The braided fiber uses capillary action to
absorb excess solder when heated. Soldering braid is woven copper and when we heat it
up, it?s going to absorb all the excess soldering and capillary actions here. Now we work into
the joint and you can see the braid get saturated with solder. We move on down the line, find
a fresh piece of braid and use the same action here. On our next section, we're going to
use our solder suction device. To use it, you simply depress the plunger. It locks.
Then to release it, you press this button on the side and it creates suction for a second.
So let's go. I'm going to remove this joint somewhere to the way I made it, applying heat
to both parts and waiting for it to bubble. I get the nozzle right on and pull the trigger.
We do not pull the iron away first because we want it as hot as possible when soldering
iron comes in. So now we know the basics of soldering and desoldering on circuit boards
and now we're going to move on to another practical thing and that's cable repair.
