I've got one on the list for when/if funding becomes available. Swiss-- MBR.

I've tried a Korean one and wasn't all that impressed.

Solder is easier to handle and has more repeatable properties IME.

I've never bought one, but had a hell of a lot o fun with one of these

at a trade show. The folks from Japan were there too.

The standard show-off trick is to let people solder onto glass. It works great. I even tried to edge solder two microscope slides together like how they glass seal LCD displays. It worked fine.

The tips on those things are sort of fat and clunky, but that's just how they are.

Forgot to mention- they don't seem to make angled tips. you have to use the gun perpendicular to your work. They forget to mention that in the sales brochures. You have to solder straight down. The unit is just a big clunky soldering gun until you pull the trigger for the ultrasonic transducer, then the fun starts. I can hear them, but it's not as horrible as standard ultrasonic welder.

Thanks. I emailed them to find out how much they are, but they have that $1k sniff.

That is rather a bit of exotica. And yes, as i understand it, ultrasonic "soldering" (really more like wirebonding) is required to not contaminate the Indium. Happy hunting.
