*EXPERT LEVEL* Soldering Tutorial #4 TTC Avionics

May 01, 2020
Alright, now we're about to connect a cable to a panas connector on our pen style connector, go ahead Jen, go ahead and read each step. The first step is to prepare the connection and prepare the braided cable. Well, the braided cable. I'm ready now. I intended that in the solder container, as we talked about in the previous steps, I inserted the terminal into the phenolic Bock. I took my terminal. It is inserted in a phenolic block. See placing the end of the stripped and tinned wire into the cup. Very good, I stripped this cable. long on purpose so you can see, I'm going to place it in the solder cup.

Well, the insulation must not be embedded in the solder joint and must be less than two wire diameters including the insulation. Well, it's obvious that the insulation doesn't touch the connection, however, it's a lot more than one, I mean more than two lengths of wire, so I need to trim this connection, so I'm going to trim it, remove the wire and use cutters. of wire to cut the cable to the desired length. Now I'm going to put my wire back into my terminal and I'm going to check to make sure that my insulation is now not touching the top of my solder cup, which it isn't and that I don't have more than two lengths of wire, which it's right. now you have a length of wire, so you're within that range of two that we'll call eggs, okay, clean the terminal with the NASA brush, here's an approved solution.

I'm going to take my rubbing alcohol and I'm going to clean up, make sure. you put inside the hole this outer cup and then we on the outside tin the terminal by inserting the end of the solder into the cup and place it on the iron so that it touches the solder on the side of the terminal at the same time. Time failed on a cup with solder and covered this entire inner surface. Okay, now I'm going to apply flux to the solder cup and let it run on the outside. I also want to remove the gold from the connector so I can do this. that I need to apply solder, so I'm just going to cut the solder.

I'm fine. I'm going to clean my solder. I'm going to place it inside the cup. I'm going to clean my

soldering

tip. I need to tin my tip, place the solder back into the cup and now touch the stud at the same time. I want to make sure I have enough solder on the cup to remove the gold and obviously I can't add a wire, some people would. Heat it up and insert the wire which we don't want to do because that introduces a lot of contamination so the next step F to absorb the solder from the twist insert a braided wire that has been coated with flux and place the tip of the iron against the wire, the wire will It will heat and melt the solder, which will then wake up on the stranded wire.

Cut the wire that has the solder wick. The absorption process will be repeated until there is no solder left to remove. Well, there are a couple of things we can. Do I want to remove that solder? I can use it to connect another wire with blocks to remove it, the first thing I do, even though I have so much Satur in there, I'm going to use a very thin wick to start. Use a thin wick. place the flux on the wick. I'm going to clean my

soldering

iron. I'm going to absorb as much of this solder as possible.
Now move it down. I'm going to make sure the outside doesn't have any goop. of solder, so I can even lay it down and wrap it, soak it, there we go, it looks pretty clean, however, there is solder on the bottom of that mug, since they are soldering the bottom of that mug. I'm going to do exactly what they said: I'm going to take the wire, I'm going to strip it, I'm going to clean it, I'm going to flex it, I'm going to put it inside the cup and I'm going to take out any debris. excess solder to do that, although I actually have to add a little bit of solder to form a bridge and soak it into the wire so the bridge goes in and I just run my iron along the outside of the wire so the solder follows it.
I lift the wire up and suck it up, then leave the solder cup clean and take care of my wire, put it back in the holder. I'm going to cut that piece off because it's a joke and Jay's next step will be to clean the terminal. with the active brush, first I'm going to clean it like a brush. I'm going to place the chemical wipe on top so I don't make a giant mess that absorbs any excess flux that gets in and out. inside, as much as I can, make it nice and clean step 2 you're going to put the wire in, connect the terminal wire to the spring, okay, so I'm going to put the wire in, I'm going to connect it to the spring before I insert the wire that I prepared before before inserting it, wow, this one before inserting this into the bracelet.
I just want to hit it with alcohol, clean it, I'm going to insert it, although I'm going to clean it again. I'm going to hold it, leave it on top now I want it to go right into the cup so it's a little bit there and it looks good, okay, clean the connection, so now once again I'm going to clean the connection with my butt. and brush, wiping it lightly while keeping the wire against the back of the cup, a good mechanical connection. I'm going to try it again a little further back, I want it against the back of the cup, here we go, okay, step four, you're going to cut this honor, okay, so I'm going to add flux.
I'm preparing it to solder it. I'm going to cut the solder, a new piece, cut it, clean it, okay, step 5, clean the soldering iron, okay, now I have to prepare the iron and I take a soaking bath, wait, clean the iron, remove the oxidation, it's okay, step six, you're going to place the iron, place the clean tip of the southern iron against the terminal to connect both wires into the terminal at the same time, okay? What I want to do is form a solder bridge and I have to touch the wire and the wire at the same time and form a bridge by simply applying a little bit of solder between the iron, the wire and the cup.
You don't want to go against the back of the cup because it will leave a little spike on the back. I need to form all three, then I'll touch it for about three seconds max, allowing the flux to bubble, it will bubble and then I'll see it solid. I don't want to add too much solder because I want a nice concave connection between the wire at the connector pin. I'm going to shape it and then I'm going to remove the solder and lastly I'm going to remove the iron so I need to clean this again because it rusted while I was talking, I'm going to place this against the wire and the connector itself will form a bridge and then I'll add enough solder, remove it and eliminate step seven now that we have applied a small amount of solder. to the joint where the wire in the terminal and the Tiffany we have made a solder bridge now step nine clean the connection clean the flux of the solder connection okay then we form our bridge we add our excess solder our excess which is our solder now I'm going Clean the connection to remove that flux.
Take good step 10. Inspect the connection. Remove it and make sure there is no excess solder. Any welding peak. Flow. A million things can go wrong when you do these things. Make sure. you didn't move I don't know if you can see that, but I'm looking to make sure that I can still see the wire strands, that I can still see I see the wire strands, I can still and I can see a nice fill between the solder cup and the wire. and then to make sure my insulation doesn't shrink more than two connector pin lengths, which it didn't, it's still in one length if you overheat it, sometimes the insulation has a tendency to shrink and if you get over installations of two wires, so it shrunk too much, but it seems like a good connection.
I just need to clean it up a little more, as you can see it still has flow on the pin which can simply be done by taking a chemical wipe to wipe it all down and that would be a good connection huh?
