The Hirose
IT3/IT5
three-piece connector system can be disassembled if a mother board or
daughter card requires replacement. Both the mating receptacle and the interposer are
removable. When removing a card or a connector component, the circuit boards should be
handled with great care to prevent damage to them.
Disassembly should only be perf ormed in
authorized service centers by trained personnel using appropriate tools. Failure to properly
remove the circuit boards or interposers can result in permanent damage to the circuit
assemblies.
Unless specifically mentioned, IT3 and IT5 share the same capability and requirement.
13.1 Daughter Card Removal
To remove a daughter ca rd, fi rs t remove the nuts from the reinforcing spa cers , then lift the
daughter ca rd s traight off the interposers , as shown:
Precauti on:
It is
very important to prevent excessive flexing
of the ci rcui t assemblies
during disassembl y opera tions . To minimi ze flexing of the mother boa rd, a simple
tooling plate
is sugges ted:
The tooling pla te has
clamps to stabilize the mother board
while the daughter ca rd (and
possibly the interposer) is removed.
