Designing COTS Computers for Harsh Environments

The need for commercial off the shelf (COTS) single board computer (SBC) products continues to grow as higher processing, smaller footprints and lower power requirements become more critical. For design engineers in medical, military, industrial, aeronautics and other fields, the desire for reduced size and heat also parallels an additional requirement for fanless operation. In this environment, engineers are constantly faced with the challenge of trading off various aspects of functionality to stay within a particular form factor. Finding COTS products that have all the desired characteristics and are also rated to perform in extreme harsh environments creates an additional challenge. However, there are a number of industrial grade SBC manufacturers who have been successful in designing and manufacturing COTS products specifically for use in harsh environments.

Performing Failure Mode and Effect Analysis

Failure Mode and Effect Analysis (FMEA) is a methodology for analyzing potential problems early in the product development cycle where it is easier to take action to overcome potential issues, thereby enhancing reliability through design. The tool is used to identify relationships between process and product requirements and the potential for unacceptable outputs and their effects.

Silicone Cables

Cicoil Corp., Valencia, CA, offers Flexible Flat Cable assemblies for fighter and other military aircraft applications including targeting pods, fuel control systems, and missile gimbal and guidance systems. The silicone cables can be shaped to fit very tight spaces, low weight, and a broad temperature range extending from -65°F to +260°F. The extrusion process used to manufacture the cables produces a one-piece silicone encapsulation that will not delaminate or degrade due to vibration or exposure to oils and chemicals.
