Hello Zhang,
There was once an IPC D-34 Backplane Subcommittee and they were in the
process of developing updated acceptance criteria for press-fit
connectors for IPC-BP-421, but that effort did not result in an update
to the BP-421document. Instead, the subcommittee updated the acceptance
criteria and submitted it to the IPC 7-31b IPC-A-610 task group.
The material in section 4.3, Connector Pins, of IPC-A-610D,
Acceptability of Electronic Assemblies, represents the updated criteria
from the IPC D-34 subcommittee, which disbanded after the publication of
IPC-A-610D.

Hi Zhang,
IPC had a couple of documents IPC-BP-421 (backplanes with pressfit) and
D-422 (design for backplanes) Unfortunately they are really old (early
80s) and we could not get the committees to complete an update.
Best regards,
Dave
