Another question I have is, what does it mean to "tin" a wire? I read about this in a related post, where SUBSPACE said,
"I soldered up six DB25 snakes a little while ago, it's not too difficult. Just tin each wire and soldering cup first, then use a "third hand" to hold them in place while you work." |
You want to get solder on the wire and the connectors first, before you join them together....
so don't put a bare wire onto the soldered connector...it just makes it so there is less chance of a bad solder joint "cold solder" or whatever it's called...
Also, for whatever reason(it is important, i'm just not technical), don't touch the solder and iron together..or you'll have conductivity problems, which will give you greater chances of a bad solder....touch the iron tip to the connector or wire and then put the solder on the heated surface until it melts...
So "tinning" is kinda "pre soldering" the two surfaces you will be connecting. And then reheating (usually the connector), and placing the two together, until you see them join.
I wish I could be more detailed and articulate with the reasoning, but hopefully you get the idea...
