This time it will be a very short post – there is not much to write about 🙂 . Below I will present a very useful tool in every electronics lab – a simple PCB vise. Often you will need to hold the printed circuit board during soldering or testing.
When you have soldered big compoents that are sticking out from the PCB all operations that you have to make on the PCB are getting very difficult.It is almost impossible to make it lay flat for further soldering or testing.
I’m not the first person who is trying to make an PCB holding tool – there are a lot of vises and other holders on Thingiverse. However, I haven’t found any project that is suitable for me. That’s why I’ve decided to design it on my own.
It took about 2.5 hours to complete the whole project (including printing). The vise consists only from 3 different 3D printed parts and 2 M6 threaded rods with 6 nuts – it is very easy to make one. Four of six nuts have additionally printed knobs that tightly fit on them. The vise has V-shaped grooves compatible with PCB,s up to 2.5 mm thick. The PCB can be mounted in 4 planes (tilted, vertical, horizontal).
In addition, there are holes for cylindrical neodymium magnets 10 x 4 mm at the bottom – also for “press-fit”. This vise was designed in that way to be relatively easy to print on a 3D printer. It is quite small – only 75 mm in width and 32 mm in height so it doesn’t take much valuable space in your workshop.
I want to use it also for hot-air soldering, but I will probably need to slightly redesign it and print it from a temperature-resistant material (eg. poly carbonate).
Recommended 3D printing parameters [FDM] :
- Layer height: 0.2 mm
- Printing speed: 40-60 mm/s
- Filament: ABS/ASA
- Infill: Honeycomb 30% or more
- Outlines: 2 or more
- Top/Bottom 100% layers: 3 or more
- Support: Yes – Inside the nut pockets
- Nozzle diameter: 0.4 mm
