Hi all
I am currently in the process of laying out a schematic that has a USB 2.0 Micro USB connector, which will be connected to a portable device that has a USB connector. The portable device needs to only supply power and some initial communications to the board with the MIcro USB connector.
For the Micro USB board, is it best to lay this out as a 2 layer or 4 layer PCB (this is going in production)? A 2 layer would be cost effective, however with 1oZ copper and FR4 1.6mm size board, the track width and spacing of the D+/D- tracks might prove to be tricky. I am also concerned about passing EMC with a 2 layer board. Any advice would be appreciated.
Secondly, please could someone advise on the EMC tests that I would require as the unit is not self powered but receives its power from another source i.e. portable device.
Thanks in advance.
