5.1 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 220-pin connector is split into
two connector rows and results in a total of 440 pins and four connector rows. These
connectors should be capable of driving up to 6.25GHz Low Voltage Differential Signals to
meet the requirements for PCI Express signaling.
5.2 COM Module and Carrier Board Connector
5.2.1 Module Connector
The pair of 220-pin 0.5mm fine pitch board-to-board connectors may be held together by a
plastic carrier during assembly to allow handling by automated assembly equipment. 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
two 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.
