Exactly, especially for desoldering work. The stuff cannot be beat. Havnt tried wonder or wbt but im sure their leaded eutectic products are great along with the specific kester stuff.

I wouldnt be surprised if they were all kester. I do remember doing some work in cali with some expensive stuff from frys. Thats when I realized how spoiled I am with the cardas stuff.
 
Wrong again, the electricity being pumped into the solder will readily create silver odixe. This will readily slough off compared to a leaded solder where the lead oxide will retain less brittleness and emit its oxygen thus preserving the silver.

There are many discussions on audio forums where lead free solder will lead to brittle cold solder joints. This creates significant noise when the components/pc board flex under temperature. The sound then imparted is similar to a noisy volume potentiometer that makes that scratchy noise when turned.

This is the benefit of eutectic solder as it will give more coushioned dampening when the components flex.

I have personally seen even eutectic solder vaporize off during the soldering process. I come back to the same joint and wonder where all the solder went. This can be mitigated by dripping candle wax on your solder joints after they are complete to keep it held within. Then in that case high silver content solder can be used.

What you describe does not happen. When the conversion to tin silver eutectic began, I was the world's leading user of it. I purchased somewhere between 2 and 3 tons of it, and used it with every soldering process except ultrasonic immersion.. (CERN passed me during their construction phase despite their failure to design their solder splices correctly). My work continues to operate without failures, but I will admit that it's only about 100 to 200 thousand solder joints of various sizes, from instrumentation to 30 kiloamp lap joints, and from temperatures from 125C down to 1.8 Kelvin.

There were initial concerns over tin pest at cryogenic temperatures, but the eutectic silver mix prevented it.

It doesn't matter how many incorrect discussions are out there. What you allude to is a failure of flux activation and possibly incorrect flux chemistry for the basis metal.

I've seen the result of vaporization of solder joints, but it was a result of a plasma fireball that enveloped 13 kiloamp dipole busswork, instantly vaporizing the joints, the stainless pipes around it, 1700 gallons of superfluid helium, and tossed 45 ton magnets around the tunnel.

However, the vaporization temperature of tin is way too high for a soldering iron, that's actually why they use it to float glass.

Sorry, firstly CERN does not use solder joints, the reflections caused by the differences in materials would cause serious errors in the measurements.

Secondly, I would hardly believe that a project as well planned as cern would ever have large pieces flying around. I think you have watched too much of the TV series "Lost" with the hatch station.

Thirdly, radio does not use solder. The ultrasonically weld the waveguide from the amplifier on the ground to the emitters.

Where would helium serve a purpose in radio gear or cern? Imagine having to refill cell towers or deal with the resonance of a external fluid in your atomic calculations. I believe you are trying to mock my previous discussion on sqweaky audio gear.

Lastly, you can cool something in vacuum. Its not a vaporization, its a sublimation due to a strikingly different temperature difference. Then you also have to consider the fact that the metal didnt even have to go through a phase change. The dust can move due to thermal and magnetic fields. Similar to smoking.

In summary this is why building code stipulates that power wiring use twist nylon bindings

Really? You need to tell them that they didn't use tin/silver eutectic on all of their 11 thousand buss joints, nor that they were down for two years to repair all the bad ones. (I was called in to help them with the process and design after they had the failure)

Actually. I've never watched "Lost".

The CERN site has the information on their webpage, you can easily find it if you really wanted to.

Who said radio? Ultrasonic soldering uses the ultrasonic vibration to break up the surface oxide so that the intermetallic bonds can be formed without flux.

Um, you do know what the LHC is, no? Perhaps you should look it up.

Trust me, if I were mocking you, you would know it.
Instead, I am trying to get you to learn.

Actually, code is very specific in it's not allowing solder to be used as a joining method, and there are a few reasons. But they do have multiple allowed fastening options, such as under screw heads at switches and outlets, inside clamping screws such as breakers and some better outlets, within the spring loaded push in terminals on the back of the switches and outlets (the cheaper ones, and I don't like using the push in part) as well as the bog standard wirenut you refer to as twist nylon bindings.

1. Solder cannot be used as a mechanical joint because it will creep with time. This due to the ductility of the metal.
2. Solder cannot be used for any connection used for safety bonding.
3. Solder will loosen over time if it is used under a screw head or in a wire nut.

3 is particularly consistent and not good, as every light fixture I've purchased and installed had the ends of the luminary wires dipped in solder. I cut them off and use the appropriate wire nut.

Also, I have two machines that the technician decided required solder tinning of the ends of the stranded wire to make it easy to put into the din rail terminal blocks. As a result of that, I had to implement a routine maintenance procedure to re-tighten every terminal in the machine at least once every two years.

btw, forum rules require the use of english.. If you have nothing to say, say nothing. Otherwise, discuss. Thanks
