[Arm-netbook] HDMI High-Frequency Layout: Recommendations--Taper

[Luke Kenneth Casson Leighton]

okaay, so this is what i've done: expanded the layer 1 keepout
(manually) to as near to 15mil as i can get.  then added 2 keepouts on
layers 2 and 5.  the line on the right is the board edge, so it goes
*right* out: the connector shield is there, i figure it can catch EMI.
plus there's layers 3 and 4 GND plane.

layer 5 is over BOTTOM (6, blue), that one i made just a rectangle,
extending out an extra 5 mil.  however there's obviously VIAs in it
which... really... why make it 5 mil beyond and you still have those
VIAs?  also, should i put a horizontal track across on Layer 5, say
10mil wide, between the 3 GND vias down the middle?

layer 2 is under TOP (1, red), the shape is a little more... slightly
messy, it goes round the connector (again extending right out over the
board edge, otherwise not enough space to maintain 15mil clearance),
and this time because there *is* no keepout area on layer 6 (should
there be one? i think i should, really.... hmmmm.) i brought the
keepout to within 15 mil of the ESD...

hmmm...  i'll add an extra keepout area around where those red (layer
1) tracks are, i think.

thoughts / corrections appreciated
