Ruggedization

Extreme Environments Demand Extreme Engineering Solutions

X-ES is a leader in designing advanced, embedded computing products for the harsh environments seen in military and industrial applications. We utilize best-in-class design, test, and manufacturing methodologies to design, develop, and manufacture products that deliver reliable operation in the extremes of temperature, shock, vibration, and environment.

Ruggedization Options

Ruggedization Levels

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 their end application. These levels allow a customer to tailor a solution to their application by selecting the range that best suits their needs for thermal, vibration, shock and performance.

Ruggedization Levels

Standard Air-Cooled - Level 1
Operating Temperature	0 to +55 °C ambient, 300 LFM, per MIL-STD-810F 501.4 Procedure II and Method 502.4 Procedure II
Storage Temperature	-40 to +85 °C ambient †
Vibration	0.002 g²/Hz, 1 hour per axis from 5 to 2000 Hz
Shock	20 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
For standard commercial applications. †If the manufacturer's advertised storage limit for any component used within this product does not meet these levels these tests are performed during qualification.
Rugged Air-Cooled - Level 3
Operating Temperature	-40 to +70°C, 600 LFM, per MIL-STD-810F 501.4 Procedure II and Method 502.4 Procedure II
Storage Temperature	-40 to +105 °C ambient †
Vibration	0.04 g²/Hz (maximum), 1 hour per axis from 5 to 2000 Hz ‡
Shock	30 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
For applications requiring an extended thermal range as well as increased shock and vibration requirements. Note: Level-3 ruggedization requires special consideration at the system level. Contact X-ES to discuss specific environmental requirements for rugged air-cooled products. †If the manufacturer's advertised storage limit for any component used within this product does not meet these levels these tests are performed during qualification. ‡5-100 Hz, PSD increasing at 3 dB/octave; 100-1000Hz, PSD 0.04 g²/Hz; 1000-2000Hz, PSD decreasing at 6 dB/octave
Conduction-Cooled - Level 5
Operating Temperature	-40 to +85°C board rail surface temperature, per MIL-STD-810F Method 501.4 Procedure II and Method 502.4 Procedure II
Storage Temperature	-55 to +105 °C, per MIL-STD-810F Method 501.4 Procedure I and Method 502.4 Procedure I †
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
For rugged applications requiring an extended environmental range and conduction cooling. †If the manufacturer's advertised storage limit for any component used within this product does not meet these levels these tests are performed during qualification. ‡5-100 Hz, PSD increasing at 3 dB/octave; 100-1000Hz, PSD 0.1 g²/Hz; 1000-2000Hz, PSD decreasing at 6 dB/octave

Air-Cooled Products

Commercial products are intended for use in benign operating environments or application development. X-ES offers two levels of air-cooled designs for either standard commercial or extended temperature. Rugged Air-Cooled Level 3 products provide both a wider operating temperature range as well as increased shock and vibration tolerance over Level 1 standard commercial products.

Conduction-Cooled Products

Conduction-cooled designs are more rugged, with stiffening on the top, bottom, and center of the product. Wedgelocks at the boards edge provide a stable, low-impedance thermal path and provide mechanical integrity between the board and the chassis.

Custom Ruggedization Requirements

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 coatings, are available. Contact X-ES Sales for more information about available options for a specific product.
