I've always been impressed by sprite's work. A good example of their skill is contained:
"Now obviously, the fact that this gives us only 12 of the 16 pads is a bit of a shame. The only way to get those extra pads is to use an extra-expensive PCB manufacturing process that uses either microvias or can route tracks between the pads... or you could cheap out and do something crazy like dead-bugging the chip."

- foldr 5y agoIf the four center pads are GPIOs, then you can put a single 0.45mm via (0.2mm drill) in the middle of them and tie them together. That gives you one extra pad at least. I’ve done this before with JLCPCB’s regular process.

- buescher 5y agoThat's very nice dead-bug work. I'm surprised he didn't stake the wires or encapsulate the whole thing in glue, but since he brought everything out to tiny LEDs placed between pads, maybe staking was neither necessary nor convenient.
