Please bear with me on this one......
I have a 12 layer PWB(Backplane) with 8 ground planes(all 2 oz.).
Each connector on this assembly has several pins that connect to
all 8 ground planes. Each connection is thermally relieved by 4
separate .010" traces(spoked). Each trace is .035" in length.
The connectors that are on the top layer have been successfully
flowsoldered, but I have several on the rear layer that require
handsoldering. I am concerned for the handsoldered connections
and any repair required to the top connectors following
flowsolder.
Does anyone have experience with this type of design and/or are
there any guidelines that might help me in reevaluating this
design.
Thanks in advance.
Harlan
