Loved that you took so much effort to find this method! As for ceramic PCB, the easiest way is to cut it is the "green" state (LTCC). You can then also easily create multi-layer boards and drill vias using a laser. As for your question about the crust on your silver: it is silver oxide. You can avoid this by heating in a vacuum oven. This is not complicated, just use a small surplus dental oven. These generally have a vacuum seal and can be bought very cheaply (and are programmable)

The highlight of these videos is always the part where you mention how easy these things are to make at home. "The only tools we're going to use in this technique are a CO2 laser cutter and a small kiln." Always cracks me up.

Used to work at a company that manufactured thick film substrate circuits, including screening resistors (this was in the seventies). DuPont was the place where we got our inks from. The silver conductive inks that we worked with actually included 7% or more of palladium or platinum. I recall the binder being a petroleum base. Over time the ink would dry out/get thicker in the large cold cream size jars they would come in, so we would have to add a relatively thick thinning agent to bring them back to a screenable consistency. We used 400 stainless steel mesh stretched across relatively small steel frames that fit into a semi automated screen machine. The largest ceramic we would screen would be a little more than 3 square inches. Most were the area of a 14 or 16 pin dip package. The kiln was a multi zone chain linked belt that took 35 to 100 mins for a substrate to be fired, depending on what particular inks were being fired. On a separate question, what about cutting gorilla glass?

not to mention unravelling analogues to secret formulas.

MACOR shrinks A LOT when you fire it afterword. In order for the glass to fuse in properly, its coefficient of expansion must match that of the alumina, or it will form micro-cracks. There is a process using manganese & molybdenum to form metal-to alumina bonds. This is used in the manufacture of argon laser tubes (mentioned in some Coherent patents), & is very robust against stress & CTE mismatch. There is also a "silver palladium" process used by RCA in the 1990's to manufacture thick-film hybrids.

Definitely a video on the kiln pi. That's a very useful build. But tool videos in general are always appreciated.

Spitballing here, but couldn't you cut grooves into the surface like you mentioned was possible with the water+CO2 laser combo then use the groves for the traces?

I’ve no experience of laser cutting, so that was truly interesting. Thank you. Silver paste sintering I’ve done quite a bit of though and I’d love to hear if you’ve tried sintering to fused silica. It’s a little different… Incidentally, after scrubbing your traces to remove the oxide, lift the residue off the alumina by a quick rince in nitric acid. Another approach is to use a vacuum furnace to avoid forming the oxide layer. Used small dental furnaces can be found for very little money.

Hey, the colour of the plain glass is probably due to sodium vapour emission. The fused silica won't have that, it also won't have inherent lattice defects, maybe that's why it cuts better.

So if you could etch pockets very accurately can you use the laser to directly etch the circuit board and then fill the "pockets" with the silver paste?

What a *SUPER* useful video! You’ve opened up an entire new class of material for makers and scientists! I’m actually not at all surprised that the technique didn’t work for glass: Alumina has a relatively high thermal conductivity (anywhere from 0.5 - 1x that of steel, depending on the alloy and heat treatment). Thanks to that, the thermal energy can be quickly conducted away to the surrounding areas and transferred to the water, so it’s acting as it’s own heat sink. Glass is about a factor of 30 less thermally conductive, so the energy can’t dissipate. Fused silica has very(!) low thermal expansion, almost a factor of 10 lower than alumina, so there’s way less thermally induced strain to begin with. (I suspect you might even be able to cut it without the water, have you tried that?) Anyway, a fantastically useful video, thanks!!

Hi Ben, I wonder if the glass coating after the sintering step could be removed by a quick etch in HF? Depending on how thin it is. Silver is somewhat attacked by HF, but much more slowly than glass. If there's only a few-micron thick layer due to surface tension of the molten glass, it should be removed quite quickly. Alumina is also attacked by HF so you might have undercut issues if the etch time is too long. P.S. I think it would be neat to look at the traces before/after sintering with your SEM!

alternatively burn in pouches in the ceramic at the traces and use the photolithography mask idea in combination. add more trace so you can etch away mask and part of the trace later to ensure still having enough left over trace after wards. assumes that the material inside the trace is more usable (which the video suggests)

It's been a while now, but I've had quite some success cutting and engraving Keraflex unsintered porcelain sheets with a CO2 laser in my lab. If I remember correctly the sheets are the same thickness, if not thinner, than what you are using there. They are fairly flexible in their "raw" state. You'll obviously need to sinter them, but the cool thing is you could shape them before firing. When laser cutting it in its unsintered state the cut line seems to sinter which makes the unsintered parts easy to separate. Be aware that the powder created in the cut line will wreak havoc on your linear guides and bearing surfaces, but I assume you're pretty familiar with that by now 😁

But laser there is one of the pulse lasers, not sure co2 can do that, and there probably would be microbubbles as well but really small ones. With non-pulse laser, if there is no bubble then it probably won't work, essentially just because it does not provide enough power. The guys I was talking about are Avonisys, and they have some youtube channel with the name. Content there is interesting enough, applications so as they have some fun as well, only regret I really wish they do a bit more and more often

Uh, give or take the downside of plating copper over silver, which leads to porosity (Kirkendall effect). Upside, it can be annealed no problem (do use a reducing atmosphere!), which could give even better conductivity than straight plated copper (which is a bit worse than pure annealed, due to internal stress and whatnot).
