Footprints cannot find

[Gaoshen39568652]

I hereby certify that I am not simply asking someone else to design a footprint for me.

This is an auto-generated message that is in place on the “footprints” section of the KiCad.info forum. If I remove it and ask for a footprint to be designed anyway, I understand that I will be subject to forum members telling me to go design my own footprint or referring me to a 3rd party footprint site.

Hi,

I encounter some errors “footprint cannot find in any library” like the following picture.
The symbols I download from https://componentsearchengine.com/.
I don’t know the reference parameters of those components.
How can I do it?

Recommend that you search “footprint” in the FAQ section of this forum. See:

Creating a new footprint library

Introduction Where should i place my new library? Further reading: Library management in KiCad version 5 This depends on your personal preference. KiCad does not care where you place your libs as long as your operating system allows you to write to the selected location. If the library will be used to store project specific footprints then it makes sense to place the library file somewhere under the project directory. All other libs are best collected into a single directory that is somewhere…

Once you learn it; IMHO KiCad has a pretty user friendly system.

It doesn’t seem to be mentioned in the link @BobZ posted, but it is mentioned on many occasions elsewhere:

You must create your own library/s in which to place any imported or personally created footprints and your PBC must be linked to those/that library.
You cannot place imported or created footprints in Kicad libraries and you cannot use foootprints not in a library.
The above also holds true for symbols in schematic.
