When I paved over the power pins of this part with solid copper, parts of the pins became solder-mask-defined pads. That's fine here, where all 4 pins are common. It could be tricky in other situations.
Layout software and PCB fab houses both take liberties with solder masks. That can get serious for BGAs.
I kind of miss my old flip phone and kinda hate this fancy Samsung thing, but it sure has a great camera. This was shot looking into my Mantis, which is hard to do with a conventional big-lens camera.
