Solder Paste Dispenser Without Giant Compressor

Solder Paste Dispenser Without Giant Compressor

We have certainly all had our moments with solder paste. Some of us hate it; it’s sticky and gooey, and it gets everywhere. That is, unless you have a solder paste dispenser. The trouble with these is that they typically require the use of an air compressor, which can be cumbersome to haul around in certain situations. If you need a solder paste dispenser that fits conveniently where air compressors won’t, take a look at this small one from [Nuri Engineer] called the solderocket.

This design foregoes the traditional compressor in favor of pressurized carbon dioxide canisters. These are common enough and used for things like rapidly inflating bicycle tires, but for this more delicate procedure the pressurized gas needs to be handled more daintily. A rotary knob is attached to the canister to regulate pressure, and a second knob attached to a microcontroller adjusts the amount of time the air pressure is applied to the solder paste. With this small compact setup, any type of paste can be delivered to a PCB without needing to use messy stencils or needing larger hardware like a compressor.

This could be just the tool that you need if you regularly work with surface-mount components. Of course there are other methods of dispensing solder paste that don’t require any compressed gas of any kind, but as long as something is around that gets the job done, we can’t really argue with either method.
