I am using an IC in my board whose package is 6 mm × 5 mm, 72-lead LGA package.I have not done complex boards in Kicad.I believe this one is complex for a beginner like me.
The board contains 3 of these IC’s ,a microcontroller(Most probably STM32), and a BT module.The board size is not a constraint for me.
I did some literature study and come up with a fanout paln for this package.It is given below.May I know your thoughts.
The main Kicad related question is I need to know any Kicad tools exits for fanouting
2nd I would like to know the opinion of experienced people ,whether my strategy,I given in the table is fine or not.I mean do I need to make any changes or not
OK, but just so you realise, this is a KiCad focussed forum and not suited or meant for general electronics or general ECad questions, we try hard to keep the focus just to KiCad . . . whilst trying to be as helpful as possible
Well…
square pad vs round pad so how teh tool finds the optimal point for the via may be in question.
But the tool does appear to work if you select the correct reference
“Fanout routing” is a strange term that’s come into fashion somehow.
“Fanout” is normallyan electronics term that refers to the output drive capabilities of logic circuits.
What you are looking for is also called “breakout routing” or “escape routing”.
That looks like a very easy fanout. Doable in 4L for sure, probably even in 2L. Just drop a via from each pad of the inner rings, they’ve left plenty of space in there.
A web search for fanout layout finds hits which aren’t accidental. Semantic meanings of words tend to change, you can complain but you are fighting against windmills if you’re trying to stop the change.
This whole thread should have been the original post followed by a couple of useful replies from @Naib. Instead, it’s 16 posts of hall-monitoring and off-topic nitpicking. I had an AI generate a flowchart for acceptable behavior since we humans can’t seem to figure this out.
