Looking for help modifying the core slide potentiometer to match URL part

Default Slide Potentiometer in Core Parts

The current pin layout matches a PCB variant of the actual part, unfortunately, the URL links to RA4520F-10-20D1-B5K on mouser where that ‘10’ refers to the solder lug variant. I get that its not a standard way to do boards, but as I now have a bunch of the solder lug version in house, I would like to modify the part to match.

Slide Potentiometer modification

Hello,

I’ll try to get the digital data from the manufacturer. It’s really just about making sure that the slider will fit your printed circuit board (PCB) later, right? For now, I’ve requested the data for the slider RA4520F-10.

I’ll get back to you.

Regards, Harald!

Regards, Harald!

So, I’ve taken another closer look. You want a slider with solder lugs (I was on the wrong track at first).
Do you have SVG files of your slider?

Should the slider be screwed onto the PCB or soldered to the housing?

Could you please send the exact part number of your slider, perhaps with a link?

So the slide potentiometer in the core parts bin was what I was thinking about just making a solder lug version. My intention is to treat it like a pcb mount part with extra big pins if you will.

Looking at the difference between the pcb mount version and the solder lug version in the data sheet, the existing slide potentiometer in the core bin should just need the holes enlarged I think?

Am I even on the right track to request the footprint for the Slider RA4520F-10.
Once we have it, you can simply replace it in the component editor and save the slider as a new part. The mounting solder pads would then be left unconnected, or just set them all to GND. I think the editor complains if they’re unconnected.
Maybe I’ll get the footprint tomorrow.
Of course, you can also export the slider, unpack it, and then modify the PCB file…

The footprint should be in the datasheet I linked if I understand what you are looking for?

So I’ve now exported the crucial file from Fritzing. If I understand you correctly, we’d need to adjust it.

Do you have a way to modify this file so it’s right for your sliders?

Slider_Leiterplatte

Can you download and edit the file?

Nope that’s the part I don’t know how to do haha.

Alright, then I’ll give it a try.

First, I remeasured the dimensions. The solder tabs are 65 mm and 55 mm apart, respectively. Both rows are 5 mm apart.

The solder tab has a width of 2.6 mm.

But the hole in the footprint of the Fritzing component is only about 2.1 mm wide.

I’ve now set the outer diameter to 3.1 mm and the stroke width to about 0.41 mm so that the hole is about 2.7 mm.

When loading the new drawing, I got an error message.

Do I need to make copper1 a subgroup of copper0?
…or is copper0 sufficient?

Leiterplatte

Maybe someone can help us?

I’ll try two variants again today.

Regards, Harald!

So, I’ve found a workaround. BUT that’s certainly not correct. I now only have a copper0. There’s no longer an error, but during the Gerber export it warns about the missing copper layer. However, in the Gerber viewer the file drill.txt is included and also shows correct values.

I’ll upload the interim solution here; this is not a final solution.

Here’s an example sketch.

The question about copper0 and copper1 still remains.

So, for now there were no error messages. I just had to move the copper1 layer in front of the copper0 layer and nest copper0 under it.

\u003cg id="copper1"\u003e
   \u003cg id="copper0"\u003e
       \u003ccircle id="connector0pad" .../\u003e
      \u003ccircle id="connector1pad" .../\u003e
   \u003c/g\u003e
\u003c/g\u003e 

Maybe someone can double-check. I’m still not sure whether the holes will be drilled.

I exported the whole thing to KiCad again to get a second opinion. It looks like the drill holes for the slider are indeed larger.

Is that what you wanted?

Here’s the Gerber viewer. I exported the Gerber files from Fritzing.

Regards, Harald!

Sorry Harald, thought I responded to this, yes that seems right! Ill load it up and see how it goes on my end!

Alright, I’ll try asking a specialist again. Since you really want to have a board manufactured, it would be unfortunate if the drill holes turned out not to be correct.
