Off board components

Former Member

I've been working my way through all the example projects I found on the

Cadsoft site, wow... They are useful.

 

Because I want to develop good habits from  the start and I'm trying very

hard to unlearn some very awkward techniques I bring from the "other"

commercial software I was using, so I really appreciate any advice you can

give me.

 

I want to show off PCB components on the schematic, like a panel mounted

pot, or switch, or jack because I want them to be included in the bill of

materials.

 

So, what is the preferred method to do this? I see most just leave them off

the schematic and use a connector or pads for the off board stuff.

 

In the "other" software, I created some panel components that just had pads

for the PCB package. It worked OK.

 

Are there already some "off board" components like this? I've tried every

keyword I could think of to search the libraries, but no luck yet.

 

Thanks for you patience with a new user.

 

David

    You have to be consistent with what a BOM is for and what a "board"

    means.  In any place I've worked with, you wouldn't want a panel mount

    switch on the same BOM as that of the board.  The board needs pads or a

    connector for the switch wires, so that is shown on the schematic and

    goes on the BOM for the board.  The switch goes on the BOM of another

    assembly.  Then the larger unit is another assembly that shows the board

    and the switch with cable installed onto the board as subassemblies.

     

    You can put a comment in the schematic explaining what is intended to

    be connected to the pads or connector that is on the board, but that's as

    far as it goes and should go.  Think tree structure.

     

     

    Thanks Olin,

     

    I agree with your comments for the circumstances you cite. The difference

    for me is I am doing this for my own personal use and maybe to share with

    others who have the same hobby (DIY synthesizers) (similar to the situation

    Travis describes). In that community, it is typical to include "off board"

    components on the schematic somewhere.

     

    However, in a "tree" frame of mind (good advice) I could do the board in

    one schematic, use pads or connectors, then do a sceond schematic only that

    shows the pot/jack/switch connections. Both schematics can be part of the

    same project. Thanks
