Are there, or are there not, actually self-cooking pizzas?
Because it’s just cruel to tease people like that if there aren’t

As someone who treats high frequency circuits as sinister black boxes just north of blasphemous eldritch magic that’s a really, really, cool assembly mechanism; but as someone who knows just a touch about why he does so I can only live in superstitious terror of all the ways that ground plane deviates from preferred ground plane behavior.

It doesn’t taste as good as properly hydrated pizza.

So any board can be self soldering if I pump enough amps into it?

I, for one, welcome our new self-soldering overlords.

And self-igniting, very exciting! There was the time I plugged a power-converter PC board into the HeathKit H8 microcomputer I was soldering together. I slipped that board in backwards… and the voltage limiter chip, meant for 12 VDC, received 120 VAC and exploded! Silly me. ;-(

Super neat idea! Two flaws keep this from general usage, but it’s a great start!

  • The low-temperature solder he uses is really brittle compared to most solders.
  • The heating layer makes a horrible ground plane. Typically you want solid metal; the winding path he has is an inductor - the opposite of a solid plane. This will slow down the speed of signals near it, so it wouldn’t be usable with high-speed boards. There is a fix - put the heating layer between two actual planes. This increases cost, especially because PCBs come in even-numbers of layers - adding one layer means you actually add two.

The inclusion of a spoon does not bode well

Can we get a little disposable pizza cutting tool?

If you meant desoldering then I think yes you can… Don’t breath that smoke!

If you meant trying this trick on just any old board I suspect no. All that talk about which solder and the layers (fancy!) & stuff.

I think that’s a fantastic idea!

Pretty much everything I cook can be eaten out of a bowl armed only with just a spoon. But that’s only because it never occurred to me to cook things in a bag.

I feel dining etiquette is an effete affectation of the bourgeoisie!

If you switch to Bachelor ChowTM exclusively you won’t even have to cook it, just add water.
