There is several options out there for Solder Paste dispensing but it's mostly complex and expensive. By looking around i noticed one from South Africa, exactly my style. Simple construction and it looks like it can be easy+fast to use.

However, no shipping outside of South Africa and they don't even reply on my emails.
So, have you seen anything alike, without electric motor or a pump, simple to use and not so expensive? Please share or even better, if you are from South Africa, would you be so kind to buy/forward one for me?
Thnx
Hi
I have one of these dispensers, and to be honest, it's not that great. It does work, but it has a few problems, firstly, the plunger that presses down on the plug in the syringe only presses down on the middle of the plug, and as a result, the flux part of the solder paste seems to leak out past the plug. the result of this is that the paste becomes thicker and thicker the more you use it, to the point where it is impossible to dispense the paste out of the needle any more. Due to this, it means you have to squeeze the handle hard and harder, and because the whole thing is made of mild steel, the ratchet mechanism that advances the plunge quickly started to wear out.
The other major drawback with this is that once you have squeezed the handle hard enough to start dispensing solder paste, you have built up a pressure that is not easy to release, and the solder paste just keeps flowing. This is fine if you are doing lots of consecutive dots, because if you are quick enough (and you do need to be really quick), you can place the next dot before too much paste squeezes out, but it's very difficult to control.
I am now looking at getting a air operated unit that has the adjustable vacuum suck back to allow better control of the dispense volume.
Hope this helps.
Cheers
