Default WRAP IT.

Hi,

Quote:
Wirewrap when done properly gives lots of gas-tight cold welds, and an exceptionally good connection.
If you're up to this, please do...you'll be pleasantly surprised.

Ciao,

Wirewrap is a very good connection and the wire used very good (Kynar) but can be difficult to get right and can potentially cause problems that are difficult to trace if not done correctly. It works the best on square pins which partially cut into the wire and hold it tighter... but who uses those in audio? It is more difficult to repair as you have to replace the wire run to fix the connection properly, even worse if you have the problem at a multi wire connection as every wire on top of the bad wrapped one has to be replaced as well.

Seriously, our dentists are filling our mouths with mercury everytime you get a "silver amalgam" filling. Mercury is even worse than lead!

I`m going to reply here on your beliefs!..and make it interesting ....component leads are copper based they "TIN" them with lead for easy coheasion with solder...during the heating process the flux cleans any contamination between the joining connection concluding with a copper to copper connection....silver which is a better conductor and has a higher melting point is not great for soldering componets...(there is a 1 ohm difference between silver and copper based a 1000 foot wire)...the key thing I have with designing boards is to use a low melting point solder with good cleaning abilities so you dont trap flux in the joint...this very crucial in signal paths.....enough of my rant...you can all swear at me now..hahahaha...cause I`m the DIRT


Cheers!!The DIRT®

So its been nearly 9 years since this thread was last posted to.

What does everybody think in that time about silver vs lead based solder in their systems?

Does it make a difference to the sound?
If so is this improvement in the positive direction or does it totally screw it up and make things sterile?

And still I havnet really heard the difference between leadfree soldered amps and amps soldered with lead.
Or perhaps the sound is a tad heavier in the amps soldered with......

And there is no doubt, the leadfree solder is quite a bit harder to get good.
Not much, but if You are used to solder with lead-containing solder and then suddenly grips to a leadfree variant, there is some adapting to do.

But when one is as old as me, there is really no problem whatsoever.
I remember when the solder with flux inside it came. It was so difficult to lay off that flux-paste we used mostly back then.

In another fifteen years one will hear: "Solder WITH lead? Who in H*** would ever use that?"

Still Voodoo does sneak in :-)
Pure Silver has 4% More conductance than 4% Pure Copper .. true.
Now all you need to do is find then...use.. pure materials.
Nothing like extremism to enhance the enjoyment of one's downloaded I tunes :-).

you can now get both leaded and lead free solder with silver
I dont know why the industrie have used lead solder with silver
but fact is they have
or else it would never have been made

silver in lead free solder ?
I dont know, but reckon the silver 'compensates' some for the 'missing' lead
Im gonna try it, and buying a small 100gr roll right now

I doubt that
maybe only in case it makes you solder better

actually, it could make more sense to talk about flux type, and how much

my guess is 2% flux is fine for hifi
but its just a guess

halogene activated, or halogene free
water based flux, or rather not
etc etc

I've used 62/36/2 silver-bearing solder exclusively ever since I started soldering. Everyone has their solder preference, this one is mine. It flows well and makes beautifully shiny connections.

I have no interest in lead-free.
