Midplane Connection
Daughterboards can be connected to
either side of a backplane in parallel,
asymmetric parallel and cross connect
configuration. Vertical male connectors
with feedthrough pins are used with
shrouds and spacers.
Feedthrough pins can be in 5, 5+2, 8
or 8+2 row configuration. Spacers are
selected according to backplane thick-
ness to give the required resultant post
mating level. See page 31.
Optional one piece shrouds available.
See page 32.
Daughtercard connectors are the same
for front and rear using types A, B, C, D,
E and F.
Parallel Connection
Parallel connection can be symmetric,
where the daughtercards are the same
way up, or asymmetric, where they are
reversed. Column numbers are reversed
on the backplane rear with symmetric
orientation.
Cross Connect
Cross connect can be configured with
spacers and shrouds as above giving a
matrix of pins where male connectors
and shrouds coincide, or selective
loaded male connectors can be used at
the rear, with empty positions to allow
for feedthrough posts from the front.
Post options U,V,or X must be used.
When male connectors are used front
and rear, spacers cannot be used to
adjust post lengths.
All arrangements can use receptacles
with ground return shields. Consult
Tyco Electronics if EMI/RFI shielding is
required.
