Author: Laura BiddiscombeExtreme Engineering Solutions (X-ES) is a leader in designing advanced, embedded computing products for the harsh environments seen in military and industrial applications.
They utilise best-in-class design, test, and manufacturing practices to develop products that deliver reliable operation in the extremes of temperature, shock, vibration, and environment.
Three levels of ruggedization are available for X-ES products, supporting commercial, extended temperature, and conduction-cooled applications. Products may be air-cooled or conduction-cooled depending on the end application. These levels allow our customers to tailor a solution to their application by selecting the range that best suits their needs for thermal, vibration, shock and performance.

| Vibration | 0.1 g²/Hz (maximum), 1 hour per axis from 5 to 2000 Hz ‡ |
| Shock | 40 g, 11 ms sawtooth, per MIL-STD-810F Method 516.5 Procedure I |
| Humidity | 0% to 95% non-condensing, per MIL-STD-810F Method 507.4 |
If an application does not fall into one of these three ruggedization levels, X-ES offers extended temperature, humidity, and vibration screening services. Many military designs, for example, have a -55ºC operational requirement. In the case where screening alone is not practical, X-ES has experience with heater tapes and other alternative solutions. Optional features, such as conformal coating, are available.
