500 Card Edge in KiCad?

[warpie]

I'm not a PCB expert but 2mm trace width is for lots of amps. Like 4A or so....

Any mechanical thru holes on the board for switches are pots make them as big as possible for better durability. ENIG surface finish the card edge connector if possible if it will be removed and inserted repeatedly for durability compared to HASL finish.

Thanks a lot for your Template !!! and all infos
here is what i got.... it was something really complex for my level, never had a shape limit
now i have to optimize tracks, T junctions and other messy routing.... ledMeter for GR will be wired straight to front panel, couldn t do better
hope it works i only simulated the single parts of my idea
anyway it was a cool experience and funny time

Nice

i m using 0.5mm for power with 0.3mm clearance
and 0.25mm for components with 0.2mm clearance....
is this wrong? do i need bigger traces?

There's a trace width calculator in KiCad I believe. It cost you nothing to leave extra copper. I suppose the only downside is RFI inductance.

ENIG is not suitable for the edge connector, needs to be hard gold for multiple insertion durability. This can also add significant cost to the PCBs.

ok i ll check
i just discovered Saturn pcb toolkit

that s what i read... anyway it s for my personal use and fun ... so i will go for the cheapest manufacturing on JLCPCB
i can t self etching a dual sides like that

I believe you use way too thin trace for your audio ground but as I said I'm not an expert.

ok good to know ... i ll upgrade the board with all useful infos and suggestions before doing gerber

Using the kicad 500x template what i found Is that Goldfinger Is not properly on axis with edac connector!
This picture Is from a real Api lunch box ... Only 6 pins can be alligned to the connector...
My self etched pcb Is not the state of the art but enough to verify....
I was lucky to find a friend of mine who gave me his Api box for testing... Now i can measure that box...
Anybody had the same problem?
Thanks for attention

This edac Goldfinger footprint as a spacing of 3.96mm from center of each pin ... The finger width Is 2mm
This lunch box connector Is 4mm and the finger width looks 2.4mm
That s why the footprint not match...
The box model is Api 6B...
Is this a model with a different connector and so different Pin outs?

EDIT_ so sorry!!! a big mistake of mine... printer was set to autoscale at 91%
so both pcb and paper were wrong sized
now everything s fine the template is just Perfect
also checked pinOut on the box with a DMM..ok

i believe i developped about 3 pcbs with that printer scale

Yes, I agree. ENIG is not suitable for the edge gold fingers. Usually, it is plating thick gold for the fingers for durability.
