During the process of cleaning a capillary used to feed and bond the wire onto the chips, I had a small intrusive thought... and it may have won...

I'm working on retrofitting a wire bonder with custom electronics as part of a small side project(yes, to also make them cheaper). I think it's neat how the electric flame-off(EFO) gold ball forming system works when viewed at high magnification. Here's a short video about it.

Darn, this specific post is making rounds on the fediverse for some reason, totally unexpected! Hi hello there, I think I make some cool stuff myself, check out my posts.

@fafo A non-temporary option is to print a holder for 0.5µm polyester water sedimentation filter cartridges. One in the middle, fill the outside gap with activated charcoal and it works far better than even a lot of $200+ OEM units.

@futurebird@sauropods.win Done correctly, it's close to that of a solid casting. There's info in the paper.

@mich1@momou.social Hey, I'm in Munich and we have spare lab space at $dayjob. If it's still available, I think I can organize a pickup.

@Gremriel@mastodon.art @futurebird@sauropods.win This, when properly tuned, would be a lot better than powder metallurgy. But at the same time it's also going to be softer, since you can't really print harder alloys. But also, combustion chambers and nozzles aren't exactly your average kitchen towel hook or bike pedal.

@ysbreker@idlethumbs.social @futurebird@sauropods.win Yes, the DOI is right there in the post.

@adrake@sfba.social Don't even need a mill, a router would be fine. Forces for this would be in the single to double digit newton range, and only on-axis vertical. No idea on material performance beyond what the paper says, but I imagine it wouldn't be spectacular, especially given the super soft alloy. The company appears to be half-dead so I don't think anything will come out of it, but it should be simple to replicate on your own. This transducer is pretty small by the way :)
