Construction and Reliability
The PCIBPMCX2 is constructed out of 0.062 inch thick, high temp, RoHS compliant,
FR4 material. Cooling cutouts have been designed into the product for improved air
flow to the PMC sites. The components on the PCIBPMCX2 are tied into the internal
power planes to spread the dissipated heat out over a larger area. This is an effective
cooling technique in the situation where a large portion of the board has little or no
power dissipation.
A fan option is available for high thermal load PMCs or for a chassis with a lack of air
circulation.
Surface mounted components are used. The connectors are SMT for the PMC bus and
through hole for the IO.
The PMC Module connectors are keyed and shrouded with Gold plated pins on both
plugs and receptacles. They are rated at 1 Amp per pin, 100 insertion cycles minimum.
These connectors make consistent, correct insertion easy and reliable.
The PMC Module is secured against the carrier with the PMC connectors. It is
recommended, for enhanced security against vibration, that the PMC mounting screws
are installed. The screws are supplied with the PMC from the OEM. Dynamic
Engineering has screws, standoffs, blank bezels and other PMC hardware available at a
reasonable cost if your PMC was not shipped with some of the required attachment
hardware or if it has been misplaced.
Thermal Considerations
If the PMC installed has a large heat dissipation; forced air cooling is recommended.
