I just made a similar post above before reading yours here. My company owned two ultrasonic impact grinders and two ultrasonic rotary drilling/milling machines and all of the diamond tooling had to be tuned to a nodal point for the given mass and length of the tool or it would put too much stress on the transducer and the tools would not perform. We machined ceramics and other very hard materials using all diamond tooling. You did not want to burn out a transducer as, even back in the 80's, they cost about $30,000 each. I enjoy watching your videos and always learn something from them.

We've got some ultrasonic press machines at work, used for sealing and joining stuff, primarily plastic. One time, one machine had a bolt fracture on the booster, and it made such a horrible screech that could be heard outside the building, with the doors closed, over 50 feet away! Ear protection is a must! Granted, these machines are about 900W each. They're indeed picky about the dimensions of the tooling, it has to be tuned, otherwise you risk damaging the horn (transducer) or having poor efficiency.

Awesome video as usual. You asked for suggestions for applications, I might have one: would it be possible to make an hermetically sealed metal feed through in glass or ceramics in this way? For example by applying the ultrasonic energy to a copper tube from one side while inside a hole in a glass plate and at the same time heating it from the other end and applying the solder? Metal seals are known to be completely hermetic to moisture / gasses and this technique would be very useful in vacuum systems for making a quick hermetic feed-through.

50 years ago a friend gave me a small tube of a special solder that was also a special alloy that did pretty much the same thing the ultrasonically applied solder does, but 'wetted' and reflowed well using a conventional Weller 60 watt soldering Iron. It was about the thickness and consistency of standard spooled 60/40 resin core tin lead solder and left no visible flux residue. It was coiled up in a plastic tube similar to the 'free' solder sample you often get when you purchase a new soldering iron. I didn't have much use for it at the time, but over the years I used it to solder things I would not normally have been able to solder; such as Nichrome wire (but not the part that could glow red hot), Aluminum, Stainless, etc..... My biggest use for it was repairing solar cells (which were extremely expensive back then, and were always round) It was the ONLY way for me to successfully reconnect broken tabs to the metalized glass on the back,. or to bridge over surface cracks in the tiny treelike pickup paths on the front surface of a cell. I never tried soldering to plain window glass. I never asked my friend for more of it because I still had some, and he passed away long ago. There was a name on the plastic container but I am in my mid 70's and can't remember that name now. I only mention this because you may be able to do some research to find who made it and what was in it now that you know that it did exist,........ at one point in history...

I wish I had seen this 4 years ago when I was working on a research project that required soldering to doped silicon -- we ended up using this weird proprietary compound called nickelex instead, and it was a disaster and our contact quality sucked, and this was despite the fact that said compound was 1% HF acid. This is so much simpler and safer... I'd be really really curious to see if you get good ohmic contacts across silicon oxide -- if you could do a quick IV sweep to check I'd be /extremely/ grateful. I'm also really curious if that silicon wafer holds up to a post-solder anneal, and if it improves the contact quality at all. Again, thank you so much for this!

@@hedgeberg : Not ultrasonic soldering, ultrasonic welding. I understand it to be _the_ norm for semiconductors, using gold wires that are ohmicly bonded to contact points on the semiconductor die via ultrasonic actuators of some sort. I have neither training nor experience in this field, so I might be misunderstanding something about the whole subject (for instance, maybe the bonding is actually to pre-deposited solder instead of directly to silicon?), but I've run across mentions of it intermittently for years.

It absolutely makes sense for the commercial solders to contain zirconium. It is even more active than titanium, to the point that it can react with superheated steam to form hydrogen and zirconium dioxide.

This is a great demonstration. A customer handed an automotive ABS module made by Bosch to repair. (It had several broken/corroded bypass capacitors) Needless to say I failed on an exemplary level because I forgot about ultrasonic soldering in general. I couldn't figure out why the heck solder wasn't adhering and as to why the original components were not coming off at all. It was literally the biggest single slab of silicon I've ever seen with even more small COB's on top of it. Needless to say, I would love to invest in this technology so I can expand my repair services to say the least.

Very interesting! Can you tin a surface with active solder, then use regular solder to connect to the tinned area? Perhaps you could use PWM to decrease the ultrasonic power? Is your soldering tip made of aluminium? Gallium would dissolve it (although maybe not when alloyed). ITO would normally be bonded to by first masking and using PVD to add Ti-Au bonding pads. That's how we did it, anyway.

There was almost no information on anyone having successfully performed that DIY. For light and strong metals with excellent heat dispersion properties, magnesium looks really good.

Very interesting! 10:30 It looks like a soldering iron tip does once the iron plating has worn through and the copper inside is exposed. Usually it degrades quickly when this happens due to flux + heat. In your case, likely even faster, since the copper likely can't take the ultrasonic scrubbing as well as the iron plating. Is the conductivity approaching copper? Could this be used for making circuits on ceramic substrates? I was thinking heated ultrasonic tip on an XY robot effectively printing circuit paths.

Thanks, man. Before the video I did not even know the thing existed. If I needed to connect a wire to a piece of glass I would probably look for someone who has an old vacuum metal spattering chamber in his garage liberated from somewhere during the soviet era decline and ask him to put on a thick enough layer of silver to accept a regular Pb/Sn eutectic solder joint on all the required spots. It is good to know that there is a technology that makes it possible to get the same result at home with no bulky and noisy equipment needed.

My fathers uncle, whatever you call that in english... Tried to weld a glass bottle to a piece of metal. I never heard if he ended up succeeding, but he tried a lot, again and again. Didn't give up. Told my teacher about that story (i was studying blacksmith) and he said it was impossible to weld glass to metal no matter what. Well i guess it's possible, just in a really weird way xD Really cool video! And interesting. I just repaired my stainless steel watch with a ts100 soldering iron and lead free solder ;) Spent quite some time to find some this weird liquid that makes it possible to solder stainless steel. That stuff works, but seems pretty corrosive if you don't clean it off. Got it from a hobby shop that specializes in those small train models. Guess they use that stuff to solder train tracks together? But hey 10$ for the liquid, 130$ to get the watch repaired in a shop with fancy tools... Yep i'm happy :)
