Some thoughts


 

This package looks very capable and seems easier to learn than Eagle
and with out those pesky limitations. I like the idea of the
microwave tool bar.

I think I would prefer to specifiy a standard default footprint
attached to each part instead of having to specifing a footprint for
each item in the netlist.

I plan to make up some parts this weekend. I dont see foot print for
several of te parts I need such as 48-TQFP, 20-PLCC, SOT23, SOT89
Micro-X, SOT323 etc.

Libraries always seem to be a big issue with EDA. One of the things I like about Kicad is it separates schematic component libraries from footprint ones. Like you I already had to create a part, a relay.

The Kicad site has a contrib library so perhaps we could use the group files section for the same sort of thing.

You can, if you want.

You can edit the component in Eeschema and fill the field "pcb" with the name
of the desired module/footprint.

A more convenient method is to create .equ files and use the automatic association command, with cvpcb.

This is because for many components, the "standard default footprint" depend on the value.
Diodes, Polarised Condensators are an example.
And for most of components, you can use a SMD version for a project, and later the "standard" version for an other project.


With a .equ file you can have a "standard default footprint" which solve this, because the .equ files can be spécific to a project.

here is an example ( seen kicad/modules/devices.equ)
'680K'??? ? 'R4'
'1M'??? 'R4'
'2,2PF'??? ? 'C1'
'3,3PF'??? ? 'C1'
'74HC00'??? ??? '14DIP300'
'74LS00'??? ??? '14DIP300'
'74HCT00'??? ??? ?'14DIP300'


* .equ file gives the standard default footprint from the component value, and can be created by your favorite editor.
And the editor replace command can very fastly change the 14DIP300 to SO14E for a SMD based project...

in kicad/modules/ you can find some? .equ files.

Do not forget to configure cvpcb, to select the .equ files you want.
