@WereCatf Where are you from, maybe i can take one from your hands?
Or you can use them to master the black art of smd

@Douglas-Kryder Happy? Yes. Hand soldering may be old school, I use it to just get the job done. Those tweezers are spring loaded so hold small parts nicely. If you don't like the tweezers that they ship with the unit just about any other tweezers would fit in the clamp. I find the third hand perfect to hold a 0602, 0805 etc cap or resistor in place on a board over the tiny traces while moving in with the fine tip on my soldering iron. I may also use some tape to hold the board to my work table. I like .020"/ .5mm solder for tiny parts. For the mini USB connectors - since I am connecting just the 5V and ground legs - I cut the three other center legs off, so there won't be any solder bridges between possible USB signals in the cable.
In essence, the problem is that the very act of touching a soldering tip to a tiny placed part displaces the part off the board trace or solder pad ... this tool can grip and hold the part in place long enough to solder the first solder point on the part.

@J-Tech I live in Finland and I doubt you do live here. I could send one in the mail, but I have no idea how much it costs to send anything to another country -- never had a reason to do so before.

This is why I like solder paste + hot air gun so much: I have a nervous-system issue which causes both my hands and fingers to tremor a lot -- sometimes I can't even hold a glass in my hands unless I use both hands -- and I have trouble soldering even regular through-hole components, but with a hot air gun I don't have to be so precise. I can take as long as I want to with applying the solder paste and dropping the component in place, and one doesn't even have to be terribly precise with the paste, either, and, best of all, no need to worry about accidentally pushing components out of place with shaking iron!

@Ken-Conrad i understand why you use it. i was curious if it was meeting expectations. a lot of my work is on small boards which are off the main table and sometimes at an angle to the ceramic surface they are on so this helper tweezer would have to be able to be locked in a somewhat reaching position and i was curious if it could do so. i guess my main concern is how tight the tweezer fits in the arm since it appears to be just a friction fit. perhaps i'll just buy one and find out. thanks for the lead.

@Douglas-Kryder Sure, this is a tool that has met my expectations. The tweezers are clamped in the frame with a thumb screw so it can be held as firmly as you may want. The base is cast iron and weighs about 9oz. The frame has two clampable ball joints, so the tweezer can be moved into many positions - from tip on table to straight up. Over-all this a decently well-made tool.

@WereCatf Yes ... on this small scale perhaps we all have some tremor. I have more respect for you, to do SMT hand soldering with your issue. Solder paste will be your friend, it has the useful quality of just as the solder melts, it pulls the part into place on the copper pads.
I know some hobbyists who do small SMT work, they have told me they hold their breath and sometimes even anticipate a heartbeat so they can work between beats, or so they claim!
I could never suspect you have hand tremors while at your keyboard, your writing is always clear. Maybe don't have that glass of water too near your electronics!

You have no idea how many times I've toppled it over on my keyboard!

@WereCatf Ok, splash-proof keyboard for you!
