Remove fine wire coating to solder

<< < (2/2)

hahahah you can bet they won't be effing around taking time soldering it at factory level...so it must be staring me in the face!

Teledog:
I'll probably be flamed for this (pardon the pun),..but when in a pinch, I always have a disposable butane pocket lighter handy.
Use it "sparingly"!  Should probably flux the wire well after "the treatment".
 ..good for quick & dirty heat shrink purposes also (try not to char)

used to use a solder pot at the shop..but not exactly a benchtop tool..

SeanB:
They probably use a solder pot at the "factory " ( otherwise known as some small area in a corner) to do the enamel removal and tinning, so the easiest is just to use a disposable lighter to quickly flame the wire ends, which, while removing the enamel, will also tell you it is CCA or actual "mystery copper" that they used.

there is also a lot that use tinsel wire, which is a copper strip that is wound around a polyamide core to make it flexible and strain resistant, and to solder to that you use the lighter thing or a solder pot.

If you do not want to use the BIC method, a soldering iron set to 400C, rosin flux solder and a big blob ob the tip, while simultaneously putting the wire and fresh solder into the blob to provide flux works well. Takes around 5 seconds of holding the wire there, and having something underneath to catch the drops of molten metal that fall down.

Thanks gents I’ll try it tomorrow

Once I start I’ll have to succeed also strain relief and glue it in its shell.  I’ll have to invent good strain relief or it’ll just pull out again.  They are very tight fittings.

chrisl:
As many have said above, the molten solder blob on the tip is the way to.
Put the wire though the solder blob for a few seconds then you should have nicely tinned wire.
