I wanted to have one of those fancy SMD tweezers that I can use to hold an SMD resistor or capacitor and then read their resistance or capacitance values. However, the’re quite expensive. So I made one.
This is actually my idea a few years ago. I don’t know exactly if somebody has done it before but I wanted to do it for my own use.
I remember seeing one of those chopsticks for kids and I thought, would it be nice to use that for my DIY SMD tweezer project. So I bought a pack of those chopsticks for kids (actually I only need 1 but they sell it in packs of 4). I also bought a cheap metal tweezer.
So here’s the steps in how to make one.
1. Split the metal tweezer in two
2. Put one of these connectors
I’m not exactly sure what these are called but these are available in hardware stores
3. Wrap the connector around this part of the tweezer
4. Solder a wire to the connector
If you can solder the connector to the tweezer, that would be better but my soldering
iron wasn’t hot enough for me to be able to solder the connector to the metal tweezer.
I think the tweezer, since it’s metal, was sucking the heat out and thus the part of
the tweezer nearest to the connector isn’t getting hot enough to get a good solder
5. Do the same on the other half of the metal tweezer
6. Use cable ties and tie it to the chopsticks
7. Testing if I can grab an SMD
8. Add banana plugs at the end of the wires
9. Ready for testing….wow.. it works!
10. Here’s the whole thing with the Fluke, DIY SMD tweezer with the banana plugs.
