What is the proper zero orientation for a SMT LED?
According to screaming circuits and IPC-7351, the cathode should be on the left for a molded diode. HOWEVER, when I use Altium's component wizard to create a diode, it places the cathode (K) on the right! I would assume that IPC-7351 would be correct, but I don't understand why the Altium default would be backwards.
Does it depend on the manufacturer? How does the assembly house know which way is correct?
For reference, I am looking at the OSRAM LS R976, which has the cathode towards the holes on the tape.
Unrelated: Why does the search in the top right corner return different (and in this case, worse) results than the search that comes up when you click ask question?
