First, they should consider using better quality tips, and much, much shorter ones. Less backpressure. They might also want to consider trying plastic conical tips as well.
Second – Zephpaste, while very high quality, is not optimal for this (it’s also very expensive). They need Type 5 paste – smaller balls, more uniform. I’m surprised that they got Zeph through a 23ga tip (which I’m guessing is what’s shown in the video), much less the 27ga tip they mention in their readme. I’m a big fan of ChipQuick Low Temp Lead Free T5 – it dispenses really well, and it’s really easy to get to reflow without burning boards or components.
I’d also love to know which pneumatic dispenser that they’re using (or if they cooked one up themselves). Some of them are pretty good, some not so much.
