Hello, I am fairly new to PCB design and am currently trying to make my own PCB. I am having trouble figuring out how to tell which pin is which on OrCAD Capture 16.6.
Above is a capacitor that is in my circuit, and the second picture the PIN tab for this capacitor. How should I read this? should I use the first column as the pin number, so pin 1 is positive? or should I use order, so it would call the first pin 0, and it is positive? The footprint shown was designed by me.
Above is another part in my circuit. On this part, the "Number" column has numbers in it instead of the polarity like the CAP...? The footprint shown was created by me, I am trying to match the footprint pins to those in the circuit. The simulation uses BD140 instead of MJE15034 because I do not have MJE15034 in my parts library, on the actual PCB however, MJE15034 will be used.
Above is a third part from my circuit. On this part, both the number and order start with zero. On the PCB editor, when you place a pin/(pad?) it starts at 1, does this mean the first column is all I need? Or do I use one of the other columns and re-number the pins in PCB editor to start at 0?which Column is used to identify the pin number? The simulation uses MJL21194 but the real part will be MJL4281, which I do not have in my parts library. Both MJL4281 and MJL4302 appear to have the same pinout, so I was planning on using the same footprint for both components, to same some time and not have to design another footprint.
