6.1 Chapter Overview
The interconnection between COM Express modules and the carrier board uses two
220 pin 0.5mm fine pitch board-to-board connectors. Each single 220-pin connector is
split into two connector rows. This results in a total of 440 pins and 4 connector rows.
These connectors should be capable of driving up to 6.25GHz Low Voltage Differential
Signals to match the requirements for PCI Express signaling.
6.2 COM Module and Carrier Board Connector
6.2.1 Module Connector
The module connector for Pin-out Types 2 through 5 shall be a 440-pin receptacle that
is composed of 2 pieces of a 220-pin, 0.5 mm pitch receptacle. The pair of connectors
may be held together by a plastic carrier during assembly to allow handling by
automated assembly equipment. Module Pin-out Type 1 shall use a single 220-pin,
0.5 mm pitch receptacle. The connectors shall be qualified for LVDS operation up to
6.25GHz, to support PCI Express Generation 2 signaling speeds.
AMP / Tyco 3-1318490-6 0.5 mm pitch Free Height 220 pin 4H Receptacle, or
equivalent
AMP / Tyco 8-1318490-6 0.5 mm pitch Free Height 220 pin 4H Receptacle, or
equivalent
Sources for the individual 220-pin receptacle are (same as previous part, but with
anti-wicking solution applied) A source for the combined 440-pin receptacle
(composed of 2 pieces of the 220 pin receptacle held by a carrier) is: AMP / Tyco
3-1827231-6 0.5mm pitch Free Height 440 pin 4H Receptacle or equivalent. Note: the
part number above shown with a leading ‘8’ has an anti-wicking solution applied that
may help in processing with an aggressive flux. The other versions of the parts may
also be made available with this solution by the vendor. The module connector is a
receptacle by virtue of the vendor’s technical definition of a receptacle, and to some
users it looks like a plug.
