Is BGA Fanout Option useful ? And what about it's capabilities?

[robertferanec]

The reason why I don't use automatic fanout and autorouter is, that they don't work well for the designs I do - complex and small in size.

Thanks for the reply. Well, "Routing PCB Layout with DDR3 & High Speed Interfaces" video is ok....but the Lesson 8 video is really helpful as it explains so many things with reason.Your routing strategies are too good. As being a beginner, there are so many things to learn for me from these videos.
But the sad thing is that you are not using Automatic Fanout (and may be Auto-router too). So, you can't help me regarding those topics, will you?

- If you are not sure how to do fanout, have a look at the reference board of your chip manufacturer and see how they did that. Sometimes it is very hard to fanout a BGA, especially if you only can use through hole VIAs.

- I normally start fanout from power supplies and important interfaces (such memories),

- go from the middle to the edges.

- I do not use automatic fanout, I always do it manually.

- I always fanout all the pins from the BGA first and then continue in connecting them

- I think, this video may help you: Advanced PCB Layout (Video) – Lesson 8 of Schematic & PCB Design Course

- Some time ago I wrote How to Route DDR3 Memory and CPU fan-out for Altium, maybe that could help you too.

- And maybe watch also this video: Watch routing PCB Layout with DDR3 & High Speed Interfaces

I hope it helps. Poo, please let me know which of the videos was the most interesting one.

Hello, I have a doubt related to BGA fanout option.
1) Will it efficiently get the connection out of BGA pad.
2) What about its capabilities? Will it work for more complex connections too ?
3) What do you prefer, shall we use this feature or go with manual fanout (If this, then any trick or method to save time) ?
4) Any suggestion regarding BGA fanout.
