Footprint for trimmer potentiometer


 

开云体育

I rarely make printed boards, but I need to in this case. I am using version 8.01. I have identified footprints for all of the components except for a 1 kohm trimmer potentiometer. This has? 5.08 mm spacing between the end pins and 5.08 mm spacing of the slider pin from the line of the end pins. The footprint library seems to be based on the user choosing parts from a very limited number of suppliers and knowing the exact part number. I can see no 'generic' footprints at all, but I seem to remember that earlier versions of KiCad had 'generic' footprints. Is the only solution to create a footprint?

The preferred solution is to create your own footprint for the part you
wish to use. Sometimes you can find an existing footprint that is close,
save a copy of it in your personal footprint library, rename it as you
desire, and modify it to be exactly what you need. The process, once
understood, is not onerous.

If you know the part number google search part number Kicad footprint. There are numerous websites which work with distributors, vendors, and so on to create symbols, footprints, and 3d models which you can download and import.

Usually pots are generic so odds are very high a pre-existing example is out there.

Thank you, but I don't think I can find the part number. I bought these parts quite a long time ago.

Thank you. I will study the creation process.

If they are older parts they are likely(?) to be on a 0.1 inch pitch
maybe. That, and a pair of calipers, would make it easy to make a
sufficiently good footprint, I'd suggest.

I do use a digital slide-gauge to measure parts. But you mention? '0.1 inch': is there a new 'standard' pitch unit now?

You may find some parts on a millimetre pitch (5 mm, 2 mm) rather than
'inches converted to millimetres' (i.e. 0.1 inch as 2.54 mm).

Part numbers are generally stamped into pots.

It's a 5 mm square preset. No room.

Creating a footprint is very similar to "normal" pcb design. There are probably tons of youtube video that will show you how to do it if you are afraid of trying yourself..
Or just start with an existing footprint, "save as" you new name (create your own library!), and modify pad position, dimensions etc. Designing or modifying footprints is really something a pcb designer should know.
By the way, big resellers like Mouser and Digikey have CAD models of their parts, also in KiCad format. Schematic symbols. footprints and 3D models.
Library management can be a bit difficult to master. You'll need to add your own library. I would suggest to use Onedrive of similar for you own libraries. That makes it very easy to keep libraries (and pcb designs) in sync between multiple computers.

Thanks, Reinier. I am probably odd, but I do not like video instructions. I will study the KiCad manuals and see if I can find the 5 mm preset pot for sale by those suppliers.
