Construction and Reliability

PMC Modules were conceived and engineered for rugged industrial environments. The

PCI2PMC is constructed out of 0.062 inch thick HiTemp FR4 material. The material is

UL recognized per 94V-0. ROHS and non-ROHS assemblies are available.

A cooling cutout has been designed into the product for improved air flow to the PMC.

The components on the PCI2PMC are passive and do not generate an appreciable

thermal load.

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. 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 require attachment

hardware or if it has been misplaced.

Thermal Considerations

The PCI2PMC design consists of passive circuits. The power dissipation due to internal

circuitry is very low. If the PMC installed has high heat dissipation; forced air is

recommended.

The PCIBPMC() series has fan capability. If your PMC is "hot" please consider the

bridged carriers and choose a FAN option to keep your hardware cool. Alternatively

your PC may have sufficient air movement within the chassis to use the passive cooling

designed into the PCI2PMC.
