When other-than-self designs a chip with ghastly SCR latchup problems,
I certainly am interested.
I asked *you* to show us a design. C'mon Fred, show us something.
We had a bunch of meetings about the looks of our new line of VME
modules. VME is an aesthetic challenge to start... a pcb with a tall
skinny metal front panel. Most VME modules are coyote ugly, plain
aluminum panels with black silkscreened lettering in random fonts.

We decided to spring for custom polycarb stick-on overlays, which is
not as expensive as they used to be thanks to laser machining (the
steel-rule dies used to cost well over a grand apiece.) We did a bunch
of mockups to decide on colors and stuff, and tested a lot of
right-angle surfmount led's and hole sizes and polycarb frostiness to
get the backlight thing right. One of our customers asked for a "user"
led that he could control, so all the modules have that now, a really
nice rich amber color; he can load a 16-bit blink pattern register to
flash all sorts of ways.
We also anodized a lot of covers in different colors before we settled
on the right ones.

All our future modules will use this uniform design/color/font scheme.
My VP of operations has an architecture degree and she used to publish
an architectural design magazine, which is why this worked out well.
Most engineers shouldn't be allowed to dress themselves, much less
plan product aesthetics.
The pcb layout itself is beautiful, all the layers of it, but that was
done to please nobody but ourselves.
I guess it doesn't appeal to you. Can't please everybody.
