We typically use nonfunctional lands to improve PTH reliability for
our polyimide boards. This is based on NHB 5300 section 3K703 and
IPC-D-275 section 5.3.2.5
On a current design, our board vendor is asking to remove them based
on some recommendations he has heard in the industry. We are hesitant
to do this based on the above quoted specification.
What do you all think?
