Paste Dispensing

Whether you need to populate a factory-fabbed PCB or one made on a V-One, mount and align your board and then dispense tin-bismuth-silver or tin-lead paste onto your pads.

No more material and time wasted by using squeegees and stencils. Use the selective dispensing feature to dispense only on the pads you need.

Avoid the frustrations of hand soldering components. Whether your board is made at a factory or on a V-One, once paste is on your board gently position your components into place.


No more accidentally damaging components with a soldering iron. No more solder joints that make you embarrassed to show the board to your colleagues.

The V-One PCB Printer has a built-in 550W heated bed to reflow solder an entire board of SMD components in moments.

PCB Assembly FAQ

A single solder paste cartridge will allow you to dispense up to 11,000 0603 solder pads.

The solder paste cartridge has an official shelf life of 8 months and should be stored in the refrigerator when not used.

The heated bed can reach a maximum temperature of 240°C (464°F) in about 2 minutes. If you use your own solder paste you can manually control the temperature to follow your own reflow profile.

If you want to use the V-One mainly for solder paste dispensing of fabbed boards, we offer a special solder alloy for boards with a lead based HASL finish.

We can dispense solder paste down to 0402 components and although we officially support a 0.5 mm pin to pin pitch, some of our users have dispensed on 0.4 mm pitch IC's without difficulty. We have also dispensed on BGA components reliably.

Once you tell the software where the board is mounted, the V-One will take about 5-10 minutes to dispense paste.

Components need to be placed by hand, but once they are placed, reflowing the board only takes about 2 or 3 minutes.

Nope! Elemental analysis of our solder paste alloy shows a 0.01% trace amount of lead. This is well below the maximum of 0.07% required by IPC J-STD-006-B for lead-free solder.

The conductive ink and solder wire are also lead free. Download the MSDS to learn more.

The main difference between T4 and T5 solder paste is the particle size of the tiny balls of solder suspended in the flux. For T4 paste, most of the solder particles will range from about 20-38 μm. For T5 paste, the range is about 10-25 μm. If you want to learn more, watch this video we made about solder paste.

Simply put, because solder paste is much more forgiving than conductive ink. Solder paste tends to be drawn to the components during the reflow process so we can reliably dispense on smaller pads.


"The V-One absolutely rocks! It’s like a tiny little piece of magic. I feel like a kid with a new toy every time I use it. I love it!"

"Thanks so much... The V-One has really been a game changer for us. We are experimenting with concepts we never thought were possible before. This little machine has opened up a portal of possibilities in our research."

"I've never had a better and fast customer experience in my life! Amazing response time and clear and concise instructions. Also the built in support chat app is 10/10!"

"Awesome - as always. I wish all my tech support interactions with other companies went as well as they do with Mike @ Voltera."

"Always has the answers or works towards improving methods. Great support!"

"We were getting very fed up with screen printing. The stencils cost as much as the PCBs and come with even longer wait times, not to mention the storage issue - they were literally taking up a quarter of my office at one point.... When I heard about the V-One I thought it was too good to be true, just dispense solder paste without a stencil and no down time? It works just as promised... we are populating boards quickly and now I can get to having my office space back for you know... working!"

"Being a Hardware R&D group, your concept can really open new dimensions in how we prototype and check things out."

"I want to take the opportunity to thank you guys for having such a great customer support service. Always fast, relevant and helpful answers!"
