Example layout to help with first BGA project?

#22682

Hello,
I'm embarking on my first project that is using a BGA package with more than just a trivial number of balls. In particular, this one is a 12x12 array of balls on a 1mm pitch.

So, I'm looking for example layout to show how experienced designers handle the routing and power-supply layout for this kind of part on a 4 layer board. I expect there are good standard or "rule-of-thumb" ways to work with BGAs. I know this one isn't particularly high density, but I'd like to start with the right kind of thinking in mind.

Any pointers, or layout examples would be much appreciated.
Thanks very much,
Doug

If you use git for your kicad projects you can use the official libraries as a submodule inside that library. This way it will store the used version of the library with the project. We do this with our own libraries to prevent problems arising through changes over time.

My advice is to download the official libraries and copy/move them to a personal folder. Use only symbols/footprints from this personal library.

There are thousands of terminal blocks.

What I do is a google search on the part number (or equivalent part number) and 3D model or Kicad. Usually a distributor like Digikey or Mouser or something has it.

Re: Foot print Libraries in 5.1.5

Hi Gerard,

Forget about KIGITHUB. It has been deprecated in version 5.

My advice is to download the official libraries and copy/move them to a personal folder. Use only symbols/footprints from this personal library.

This way any time you update the libraries, you will keep the symbols and footprints already used in your projects.

And follow this link:

Cheers,
Pedro.

I should have added, that the correct github address is shown onnthe
main page and states:

Users who wish to keep symbol libraries up to date can track the

Re: Foot print Libraries in 5.1.5

The best advice is DO NOT USE the github symbols/footprints directly. 
If someone updates a footprint (unlikely for older well known
footprints, but it can happen) If you then regenerate a design, it can
pick up the new footprint without you noticing.

Always have your own copy of the libraries and work only from them. You
can keep a copy of the github masters on your system if you wish, then
just move new stuff over as required once you have verified that it'#s
ok for your use.

When you install kicad, the master libraries are usually copied to the
kicad directory

If not you can grab the lot from github, and there is also a zip of the
same on there which you may find easier to use than the cloning github
method. Use whatever method you prefer.




click on each of the first three links and they will take you the the
github page, just above the table of info you will find the master zips.






I run linux, but the structure is the same.

usr/share/kicad/ is the main kid directory for linux.

In there are:

demos
library
modules
plugins
scripting
scripts
template
 
I'm not sure where the default 3d models are. I have them copied into my
own PCB directory.


have a look at your library tables and you will prob get a few clues as
to where it is in windows.

The main directories of interest are library and modules.
If you have been away form kicad for a long time then note that there has
been a lot of changes to the library system and it's management.

What I did was copy the above directories into my PCB folder, and then
edit the paths to point there. I think I also had to add all the libs
into the tables again as well, but that could have been due to a system
re-install that I went through a couple of months ago.

I also have a couple of additional directories where I keep my own
component and footprint designs.

Thanks for your reply. All feedback is welcome. I am new to KiCad, and
I am still learning. I am slowly working my way through some video
tutorials at YouTube.

The PCB is so large because I am old, with bad eyes, shaky hands, and
I needed some space. That is one reason why I am interested in sharing
the project files. If I can share the project files, then you can take
them and make a PCB smaller if you want to. The original PCB by M0UKD
had SMD pads for soldering the wires to the PCB. I wanted through
holes to solder the wires to. So I also left enough room to get a
soldering iron in there. For the SMD parts (1206), I dabbed solder
paste on the pads, placed the components with tweezers, and applied a
hot air gun. Everything worked the first time. That is my very first
PCB, so I am quite happy with it. I just want to learn how to share
KiCad project files. I like the fact that they are all plain text
files. However, I have been told that it is somewhat difficult to
share KiCad projects files. I am not sure why, and I am trying to
learn how to do it.

The -cache.lib file should have local copies of the component resources.  That'll be referenced in your schematic, and should be in the same directory (no path).

The .net file doesn't need to be shared - that can be regenerated from the schematic by the user (and in 5.x seems unneeded for use WITHIN KiCAD ecosystem - someone else can confirm).

If you have an fp-lib-table or fp-info-cache, and sym-lib-table files, those will generally have local paths in them - best to define a variable for those, and mention it in the readme.
