As shown in attachment, there is no via from L1 to L4 and similarly L12 to L9. As I understand, L3, L4, L9, L10 layers are used for routing. then, how Layer L4 will be used?
will it accessible with through hole via only?
can you please, elaborate about layer details regarding layout planing. for example, L3 can be used for data lines while or L10 can be used for Address command and controls.
I wish to know which signals you had considered for layer 4, because it accessible with through hole via and if we use it for high speed signal, there may be stub.
I also would like to know why 4 internal layers are used for power planes (+ive supply)
All together, i am curious to know how to plan signals for layers.
I wish you, a very happy new year!!!!!
