I was referring mostly to layer 3 and 4. The diff pair is either on 3 or 4. If it is on 3 a slab of GND should be on 4 and vice versa. It's 1. Vsuply + components 2. Ground 3. HF 4. HF 5. Ground 6.

Yeah I had read a more extensive guide in a TI pdf somewhere, can find it at the moment. But TI documentation also schizo's on curves vs. corners of 35 degrees and chamfered 90 degrees. _______________________________________________ arm-netbook mailing list firstname.lastname@example.org http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to arm-netb...@files.phcomp.co.uk
