90 degree traces are mostly a problem from the old days, relating to etchant pooling in the sharp internal corners and causing over-etching. Sharp internal corners can be a very slight DFM concern when you're pushing your board fab's trace width limits, but otherwise it's fine. For high speed we don't usually care that much, and mostly just don't do it because there's no reason to, although it can start to matter a little bit if you're doing 100Gbps+ or doing mmWave stuff. At that point you actually tend to intentionally use weird angles (e.g. traces in an 11° zigzag) to mitigate the variance in dielectric constant from the fiberglass weave, for very tight impedance control. If you want to see this trick used in practice, have a dig through Robert Feranec's videos for the series he does analysing an open source dual-Xeon server motherboard. It's interesting that you brought up the issue of solder voids on ground pads, because there's a trick for that: windowpanes. Rather than using a single paste aperture on the large ground pads, you remove the default paste aperture and instead draw multiple smaller squares in a "windowpane" pattern on your paste layer. This vastly improves paste uniformity during application, and helps reduce voids.

[@dennydravis8758]

To add, worrying about trace shape while not having a matched ground plane is really worrying about putting the cart before the horse. Gotta have a tightly coupled return path for that current first before you can worry about what kinds of shapes you're making in the copper

Ground planes are very important for high-speed or high-current PCB designs. The "cheat" these days is to use a 4-layer PCB, where the center two layers are solid grounds (no routed signals). This ensures that there's a good ground path alongside every signal on the PCB. (You do need to add a significant number of vias to stitch the ground planes together, preferably with a ground via next to every power/signal via). It's a great video. X-ray is commonly used in PCB manufacturing/assembly, though normally only 2D and not CT. You opened with talking about the organization of components on front vs back. The most important thing is the PCBA's mechanical interface to the enclosure/rocket. Place your connectors and large components in the most mechanically convenient locations, and then shift around the other components to fit. That said, it's common to put all SMD components on one side of the board, to reduce assembly cost.

[@think-some-time]

I've looked at Lumafield stuff before. The CTs are as cool, of course - all CTs are! I don't care for their business model though. A few (possibly pedantic) corrections, just because this kind of thing is my day job: The IC packaging is not going to be ceramic, but a plastic resin. That's how they get it to flow around the silicon die! The connections between the leadframe and the silicon die are not airwires, but gold bond wires. 90 degree angles don't do anything to the vast majority of signals. Some designers start ranting about acid traps and conductive filaments, but mostly they just don't look nice, so people don't use them!

[@AndrewZonenberg]

IC packaging is actually a fairly complex composite material itself. You have silica microspheres of various sizes as filler with CTE closely matched to the silicon, epoxy resin to bind it all together, and various other additives like carbon black to make it opaque (transistors can act like itty bitty solar cells when illuminated and cause the chip to malfunction, one of the Raspberry Pi's had problems using chips with exposed silicon that would make the board crash when you took a flash photo of it). Also, gold bond wires are falling out of favor these days due to cost. Gold ball bonds (and aluminum wedge bonds) do still exist, but copper ball bonding is by far the most common in new products.

[@StormBurnX]

No-effort November sounds like an actually really interesting idea - not even for the obvious reasons of "hooray, more content from someone who is already hella busy" but also just a peek into the more casual, realtime side of things rather than the highly-produced and scripted content.

2:42 As someone who has designed quite a few high frequency PCBs, heres my 0.02. Traces with sharp corners really dont matter until you get above 100MHz. I say this as someone who religiously adheres to the 45 degree rule: the main reason is just for packing density and aesthetics. I think people imagine traces like cars around a racetrack, which is not at all how electrons travel. Signal reflections happen whenever theres a change in impedance - if you're REALLY worried about right angles, you better make sure you dont have any parallel traces (capacitive coupling) and a tight return path. That right angle in your I2C bus isn't an issue. The real killer is bad layer stackups with return paths all over the place. I see engineers with decades of experience making this mistake, its actually pretty insane how few layouts I see are actually done correctly. Luckily, mostly digital designs like a flight computer are pretty forgiving, so in this case it probably doesn't matter too much. It's just frustrating when I see other engineers obsessing over inconsequential aesthetic details, and completely ignorant of the things that *actually* make a difference.

[@leifhietala8074]

"...which TSA loved even less." I remember taking my RC stuff, batteries and motors and whatnot, through airport security in the 80s. I kept it in an ammo bag!

The 45 degree thing is basically a myth, even at low GHz frequencies it doesn’t make a difference at such a small scale. If you care about aesthetics, use Mitxela’s PCB trace melting plug-in.

[@KallePihlajasaari]

Yeah right angles are the worst but the 90 and 45 corners are the easiest to calculate so . Many people forget that swapping layers is two 90 degree bends at the via. Modest speed digital circuitry is very tolerant these days if you have the recommended capacitors on the power rails. RF design is a totally different beast that cannot be generalised.

That's why one should not only avoid 90° corners but 90° t-junctions aswell, you want the RF energy to follow the traces and not reflect back at you.

_"In aerospace we call this non-destructive testing."_ @9:49 No, this is non-destructive _imaging._ And very, very cool at that too.

interesting vid, thanks for sharing. On the boards: The later board isn't bad.. as you've learned, thermal reliefs can make a difference (the real trick is to design supplies that don't get warm) , you have some excess line lengths here and there. Also I'd try and put everything on one side of the board, solid ground plane on the other, digital away from analogue and RF as much as possible. Re antennas.. people sometimes say "a wire can form an antenna", but that's not true (mostly) what's true is "two wires form an antenna". like you can't get a current out of a battery by only connecting one terminal, antennas need to be balanced in some way, often against the ground beneath your feet (think large broadcast antennas). In the case of your board HALF your antenna is what you're calling your antenna, the other half is the board ground plane.. and all the stuff that has low impedance to the ground plane at the RF working frequency.

In the 1960s, my dad was a physicist who worked on high energy x-ray systems. The systems used field emission and cold cathodes to generate x-ray pulses. One of the machines put out a 4 ns pulse, that if you were in the room, not in front of the beam, the scattered radiation would kill you. Rolls Royce bought them to x-ray jet engines. They were used by the military to take flash photos of bomb detonation. They took them out to the desert and set up two steel walls. The film was on the back of one steel wall, and the x-ray was on the back of the other. They were able to set the timing of the x-ray to fire at any phase of the detonation. After Starfish Prime, the units were used to simulate atomic detonations for hardening semiconductors and other materials. The unit used a Marx Surge pulse generator to generate a 2.5 MeV pulse. My dad designed the single crystal tungsten field emitters and emitter arrays. The field emitters were electrolytically sharpened to six atoms at the tip.
