...three SMD devices appear to have been removed
Sure they're not just board options that
weren't placed?
Pads for unplaced devices have a decidedly different
appearance (in my experience) than what I see here.
Usually, the pads are shiny with solder, a remnant
I assume of wave soldering or some other similar
manufacturing technology. For a given device, a
few lead pads will be shiny, some *black*, and some
kinda look lke they've been pulled up off the board.
Sombody had a steady hand, I'll say that for sure.
Either that, or these chips blew themselves off
the board.
I wish I had a photomicroscope so I could take a
picture- you'd see what I mean.
As I said in my post, I'm assuming he gets lots
of these, and he just grabbed this one off the
wrong pile.
