create "pins" for a cartridge in my pcb design

needle 8 years, 7 months ago

i'm tryin to create a PCB

it only holds an 27c322 eprom and 2 capacitors 

so i thought this would be very easy..

 

turns out i'm busy for three hours tryin to find a a way to create the pins....

with pins i mean the part of the PCB that go into the cartridge slot.

Hi Needle,

If I understand you correctly, you're trying to place some copper strips along the board where it will fit into a slot.   Sorry, but I don't think there's a straightforward answer, and you will have to improvise.  

Depending on what's acceptable (and whether my guess about what you need is correct), I could suggest a couple of approaches.  One idea would be to drag out a couple of Vias to mark the opposite ends of each strip, change the size of the via's hole and ring using the widgets in the inspector, then draw a trace between (you can also make the trace thinner or thicker by selecting it and selecting from the "width" widget in the inspector).

Another option would be to create a custom part using the parts editor.  Start out by editing a mystery part (the one with the question mark on the icon), and for the pcb view image,  maybe you can find a useful svg in the parts/svg/contrib/pcb folder that you'll find in the folder where you installed Fritzing.

Hope that helps.

thanx for the reply :-)

 

you're correct:

i'm going to try and make a custom part, thank you for your help.

I know this is an old thread, but is there a better way of doing this yet? Maybe we could have the option along the lines of importing an image/shape but instead of appearing on the silkscreen, it could go onto the copper layers?

Eight 6 years, 11 months ago

Sorry, just realised you can already set an image to be on a copper layer - anyone know if that could be used to create a card edge or would you maybe have to find a way to trim the silkscreen also?

Jeez I'm stupid tonight - sorry for the spamming the board. I didn't mean silkscreen - I just meant that if I put an image on the copper layer, will anything be over the top of that preventing the shape from being used as a conductor or in this case, an edge connector?

Hi Eight,

If you use a copper image, Fritzing won't let you draw a trace to it, since it doesn't count as a connector. But if your edge connector is a series of rectangles, then consider using the Pad part, which is a resizeable rectangle that includes a connector, so you can draw traces to it. You could start with a single pad part, get the size and position right, then make copies and offset them. You could also do both, make a copper image, and then overlay it with pad parts.

HTH,

Aaah - that sounds just the job. Thanks Jonathan - I'll give that a whirl. I was scared I'd have to try and learn a different software package for this project... which I really don't want to - I love Fritzing. :-)

PS. As of version 0.7.5 (just released) you can put pads on either copper1 or copper0.

Any luck with this?  I'd love to have something like this as well, and not have to reinvent it.
