MCH
Systems specializes in the development of custom computer and
processing hardware to meet demanding environmental and operational specifications. Hardware is developed for conformance with commercial,
military, or customer specific design and performance specifications.
Key Benefits
Designs are leveraged from existing commercially available hardware or
previously developed system components and assemblies that have been
thoroughly qualified.
Customer's unique requirements are met with commercially available
standardized hardware and customer specific cable and system interfaces
Systems Integration and Testing - Delivered ready to turn-on and operate
Capabilities
MCH Systems has over 30 years experience in the design and development of
integrated rugged and fail safe computer systems for both the military and heavy
industrial markets. All military
platforms, shipboard (surface and submarine), aircraft (propeller, jet and
helicopter), and both wheeled and tracked military vehicles are supported with
our products.
Thermal Performance:
Our systems include thermal design strategies that allow commercially available hardware to operate within temperature ranges that
exceed commercial specifications. On demand airflow and heaters controlled by microprocessors
that are constantly monitoring environmental parameters are used in
conjunction with other thermal cooling techniques to ensure that
commercial electronic component specifications are not exceeded.
Electromagnetic Compatibility:
Equipment chassis and subsystems are designed to conform to the required
electromagnetic interference and compatibility specifications. EMI
filters are incorporated to suppress conducted emissions in the ac
power line. Power
supplies incorporate high frequency, zero-current-switching dc-to-dc
converters that provide low levels of conducted and radiated noise. External chassis mating surfaces are fitted with EMI/RFI
gaskets where required. Cooling
fan and dust filter apertures include filters for containment of
radiated noise. External
cables are shielded and fitted with EMI/RFI backshells. Internal wiring is designed to minimize coupling from adjacent
cables and subsystems.
Redundancy of critical components:
Redundant hot
swappable power supplies assure continued operation of the system
during failure mode. A multitude of fans are used to allow
system operation continuation during fan failure mode. Failure
reporting is accomplished in several ways; RS-232, Ethernet, and discrete
I/O. Front panel annunciation provides the maintenance technician with
detailed information for quick and easy replacement of failed components.
Formal
Environmental Qualification Testing:
MCH
Systems validates our system designs and environmental integrity
through extensive qualification testing. Test plans and procedures are carefully drafted and reviewed
with our customers to ensure complete compliance with application
requirements. Testing is
performed with independent test laboratories and personnel to
demonstrate compliance with exacting specifications. Test reports are generated and include all test data and
results gathered during the testing process.
Environmental Stress Screening:
MCH Systems offers customer specific Environmental Stress
Screening on 100% of production of our mission critical systems.
Vibration, temperature, and shock testing can be performed to your exacting
specifications.
Integrated Logistics Support:
MCH
Systems provides comprehensive technical publications and integrated
logistics support services. Document
planning, development and certification are provided to support
in-house or client directed product development. Documentation is generated in accordance with commercial or
military format using industry standard software tools. Change control and configuration management services are
available for life-cycle documentation maintenance.
Operation
and maintenance, training, and logistics support documentation is
provided to support commercial and military data requirements. This material includes technical manuals, specifications,
plans, procedures, maintainability, provisioning, safety, and failure
modes.
MCH
Systems maintains a thorough knowledge of military and industrial
standards and the processes required for development, validation, and
delivery of supporting data.
