nRF54L15 Altium component file

[Oli Perez Oxalis]

Dear NordicSemi team,

Would it be possible to request the nRF54L15 CSP47 Altium component including symbol and footprint please?

Kind regards,

Oli Perez

Hi Oliver,

You can find our reference design here: https://www.nordicsemi.com/Products/nRF54L15/Reference-layout?lang=en#infotabs

The package contains the Reference Schematic and Layout source files in Altium formats, so you can copy and paste the component symbols and footprints, or even the entire reference layout into your design. You can also use Altium's "Create integrated library" function to export the part symbol and footprint to a library.

Hi Szabolcs,

Although I was confused at first and was not sure how to go about using Altium's "Create integrated library", I ended up figuring out and have been able to copy the footprints and schematic into our own internal component library.

Just to clarify for people looking at this post and wanting to do it themselves, as you go to both the schematic and PcbDoc from the reference design linked above, I have gone to the Schematic -> Design -> Make Schematic Library, where you can access all symbols, and have copied one by one the 4 different parts of U1 into my own component symbol. Similarly for the footprint, PcbDoc-> Design -> Make PCB Library, and just copy over the footprint. Note for manufacturability and assembly in house we tend to add an additional component layer pair for assembly with the component location and designator.

One last question, is there a reason why the soldermask is kept as a manual expansion instead of a rule expansion? Perhaps manufacturability considering the fine pitch of the CSP package?

Many thanks again,

Oli

Hi Oliver,

I think the reason for the manual soldermask expansion is, as you said, the tight tolerance for the the CSP package. You can have other BGA parts and modify the expansion rule to fit those, but the CSP rule should stay as is.
