Hello,
I was just wondering how people are dealing with ICT.
There is a big trend here (over the past year) to provide 100% nodal access
for ICT.
A big problem is littering the secondary side of the boards with suitable
test pads, taking up valuable routing area.
Often with SMT, the only vias on many of the nets, are to provide the test
point. (single sided probing fixtures)
I can see there are some benefits of 100% ICT, but from a designer's point
of view, we seem to be trading off the benefits of finer pitch devices.

regards,
Phil.
