They also have a pick and place machine.[1] It's a lot like the defunct Liteplacer.[2]

It seems to be a kit, not a pre-assembled unit. It's hard to tell from the documentation. It looks a bit flimsy for the rigidity required. Same problem as the Liteplacer. To download the "white paper", you have to go through the onboarding funnel and agree to being spammed, which is always annoying.

The frustrating thing about prototyping pick and place and solder paste machines is that production people want speed, which costs. The prototype-only market isn't big enough. (Has the low-cost reflow oven situation improved? The low-end ones had hot spots that would scorch a board.)

Compare this Neoden line of products.[3] No idea if these are any good. US$3000 for pick and place. That looks like a much more useful product than the Opulo machine. It can work with a wider range of part sizes; not everything has to be on an 8mm tape.

(The problem with plated-through holes, of which "vias" are a subset, is that they require a number of chemical baths which aren't worth setting up for a one-off.)
