Hi all: In PCB, which method to connect vias to power ground plane do you favour, full-connected or orthogonal-connected? I think full-connected will be better for less resistance and less inductance. Recently I have done some simulation by means of Ansoft. The result surprised me. The inductance and resistance of orthogonal-connected mode is less than that of full-connected mode. If anyone are interesting of my simulation result, please inform me. I will send it to him. Si-list does not permit to add attachment.
