And what does this exact board, dated 2010, have to say about AI assisted routing? I see the shape, but apart from that I doubt it will add anything to the topic.

Could you, as a PCB manufacturer, please explain the copper anomalies marked with violet?

More of this AI crap and this time they forgot to remove a comment about the generated answer.

Vias in the annular ring of the through hole pads? Will come back as a TQ from the PCB manufacturer. Tenting for that via halfway into the TVS pad? Either do it, with a risk of smearing the pad, or remove it and risk solder wicking.

Bring out the crimp!

More AI slop from this account. This screenshot is not from Altium, instead it found on several web pages mentioning Kicad. And who is Yannah Zhuang at HSXcircuits?

Kollade lite snabbt från Migrationsverket och det är väl lite gummiband i tolkningen av ordet frekvent. I vårt fall är ju även 7 år av intresse. Står ingenting om när under de 22 åren som detta gäller.

Several app notes and demo boards use this bad stackup for cost saving or against better knowledge. Have they passed any EMC test? You can skip to 13:00 and see some explanations about board stacks and signal energy propagation: youtu.be/cMhh-rZiW9U?is=I-BX…

We have used some Sparkfun branded RGB LEDs with serial interface in a similar package and pinout. Why not follow conventions to mark pin 1? Also the recommended pads are a bit too small for hand soldering, so rework could be tricky.

The post got me thinking about this old classic with supercaps youtu.be/EoWMF3VkI6U?is=apyn…

Looking at a monopole antenna that is vertical from the ground plane, also this approach looks "strange" as half the plane is missing. Complete, symmetric metal on the antenna side and feed underneath.

Var förbi där i maj och blev positivt överraskad. Lite avsides i förhållande till SAS gate, men väl värt promenaden.

Voltage derating and control of inrush current are mandatory with tantalum. Changed voltage rating on one cap and decreased the failure rate from % to sub ppm for an automotive application.

This board and panel has several issues. Switches and connectors with overhang will block the use of the cutter that @cazaugg posted, it will be manual bending instead. Also SMD components close to the edge.

True. As with many other things, it is not black or white, it is grey and depends. Here we don't know the stackup with plane spacing and location. Via pair spacing also matters for inductance. We need to engineer a solution that both works and is possible to manufacture.
