For best results

Follow these tips if you are having trouble dispensing your solder paste:

– Use high quality, low viscosity solder paste. It will give you more responsiveness, speed, consistency and control.

– Let the paste warm up to room temperature, this will lower its viscosity further. This is necessary for any type of dispensing machine, not just this one.

– Always use the biggest tip size possible for your application. It will lower the force needed to push the paste through.

– Fill the syringe with less paste, again this reduces the required force.

– Use a lower dispensing speed. The paste is very sensitive to the pressure build up inside the barrel and the slower the piston moves it will react in a more predictable way. 

– If you have trouble with the paste not sticking to the board, dispense at an angle greater than 45deg and lift the tip straight up when you’re done. Applying tacky flux to the board can also help the paste to stick in place.
