On a couple of data sheets namely Philips and a generic one I have,
have the Emitter as pin 3. In general shouldn't the Emitter be pin 1?

In kicad all the Emitters are pin 1 which I thought was pretty much
an industry standard, but I guess not.




With regard to pinouts, Industry Standard is a contradiction in 
terms.  The problem you describe happens all the time and in my opinion 
is the worst on three pin devices.  I make my devices based on part 
number for this exact reason.

  Hi,
 
  is there any resource for success stories about using KICAD?
 
  Not only what company but also what circuit / application and what
  package density / types used.
  I am asking again, because I would wish to see some projects about
  targeting mobile phone / smart phone
  or PDA like complexity. (Especially those parts used in OpenMoko
  1973 / FreeRunner)
 
  Thanks

Lothar,

I'm not sure what type of stories you are looking for.  I'm a first time
user.  Previous board experience with PADS.  I just completed a 6 layer (4
routing, power, ground) board approx 3.5 x 3.75.  PC104 connector, dual row
IDC connector, 240 QFP FPGA, 2 144 pin QFP devices and an assortment of 0805
resistors, capacitors and smaller parts.  Hand routed, 800 or so holes...
Fairly dense.  Waiting on the board to ship now.  Generally very pleased
with the experience.
