Screaming Circuits: LED Via-In-Pad

LED Via-In-Pad

Darn, darn, darn. More vias in those pads. It kinda makes the LEDs look prettier without any solder on those pads, but it won't make them light up any more reliable - and  light emitting diode that doesn't emit any light isn't very helpful. It's pretty clearly illustrated here what can happen with an open via in the pad, especially if you compare the two via-padded LEDs on the right with the via-less one on the left.


Plug those vias or keep them off of the pads, please. From the looks of this board, space wasn't an issue so the least expensive solution would have been to just move the vias off of the pads.
