The bar on a diode is the cathode, the "-" side. So this corresponds to the short leg of the LED or the flatted side. The square pad for the diode is the cathode side, but for a crowbar diode (the 1N4001) used as reverse polarity protection, the square pad sits on the +9V side. But, that's because it's only supposed to conduct when the polarity is reversed.

Hi Rob

So i have to fix it again? When I start populating the board I soldered (d4 d5) with the flatted side of the led to the square pad.. After that I flip this setting...

According to yours explanations I have at the moment the leds soldered at the wrong way right ?

Thx

This is the Green Bean layout? If so, it doesn't matter which one you have going which way. As, long as the the two diodes are opposite each other, it is fine. Electrically, it doesn't matter which one is oriented which way.

Yes it's the green bean layout.

Ok.... Uff....

I was thinking that I have to desolder those guys again!!
