Mechanical Design Beyond Commercial Grade

Enclosures designed to accommodate single board computers and PCI Express backplanes or embedded motherboards come in a range of form factors, including standard 1U to 6U 19” rackmount chassis, shelfmount, wallmount, benchtop and custom open frame configurations.  In addition to well designed and manufactured electronic sub systems, system packaging is a critical design element when crafting solutions for harsh environments.

System airflow evaluation charts are typically used when designing rackmount computers to ensure a particular enclosure is going to perform as expected when fully populated.

Creating Extraordinary Computing Solutions

Structural integrity is a prerequisite for any rugged rackmount system, yet meeting this design requirement can be challenging when trying to meet the conflicting objectives of Size, Weight & Power (SWaP). Thermal characteristics must be understood for each system configuration in order to provide proper cooling under extreme conditions.

This level of testing and analysis is required when designing solutions for industries such as government & defense, communications, energy, and industrial automation.

Standard products in each of these packaging options can fulfill a wide variety of requirements. However, many cases call for customer-specific enclosure modifications to satisfy a unique set of specifications based on program or application needs. This latter situation requires an engineering approach which satisfies the need for fast delivery COTS solutions, while at the same time providing a foundation for modifications to address a wide range of situations.
