Electronic – name of semi-cut headers in KiCAD

I don't know the direct method, but you can manually modify the text file *.sch (remember to backup before modifying). For every component, there is a record in .sch file, and the footprint field is normally field number 2, e.g:

 $Comp
  ...
  F 2 "Name" V 10000 2500 50  0000 C CNN
  ...
 $EndComp

the value of 0000 near the end indicates that this field is "visible", and you need to change this to 0001 ("invisible")

How? by regular expression. I used the following command in vim:

:%s/^F 2\(.*\)0000 C CNN$/F 2\10001 C CNN/

you can try sed or any kind of text-processing app to do it.

When you chose the transistor for a package, there were a number of different options that had names like this:

Q_PNP_BCE
Q_PNP_BEC
Q_PNP_ECB
Q_PNP_EBC
Q_PNP_CBE
Q_PNP_CEB

These are the pin orderings, the last three letters correspond to pins 1, 2 and 3.

You chose a BCE version, which means the base is pin 1, the collector is pin 2 and the emitter is pin 3. These pins correspond to the pins on the footprint.

Unfortunately, for most packages, the pin numbers are NOT fixed to certain parts of the transistor. You can find TO3 transistors where the case is connected to the emitter or where the case is connected to the collector. This is why KICAD allows you to choose the pinout of your transistor when you put it in the schematic.

If you change the schematic symbol for the transistor, then the pins will be correct.
