Wide Temperature Assurance Service (WiTAS)




          Service for Wide Temperature Embedded Computing

          Applications of embedded computing systems continue to improve the quality and convenience of our lives. As the world population increases,
          there are greater demands on resources and the need for automation and computing capability in remote regions will arise. To address the
          requirement for operating in extreme environments, computer platforms must follow design methodologies for wide temperature range
          operation. In addition, testing and product qualification must follow more stringent criteria to assure continuous operation. As the core of
          any embedded system, the CPU board plays perhaps the most critical role and therefore, requires careful design and validation for wide
          temperature production.
          AAEON has designed and manufactured quality embedded products for over two decades. The accumulated experience in all aspects of the
          embedded electronics market gives AAEON a strong position in the development of wide temperature CPU boards and systems.
          AAEON’s WiTAS (Wide Temperature Assurance Service) program produces boards in two temperature range categories:

          -20°C to 70°C (-4°F ~ 158°F) = WiTAS 1                  -40ºC     85ºC     OK
          -40°C to 85°C (-40°F ~ 185°F) = WiTAS 2

          Boards that pass the thermal tests of -20°C to 70°C (-4°F ~ 158°F) are given a WiTAS 1 designation and boards that endure the thermal of
          -40°C to 85°C (-40°F ~ 185°F) are assigned a WiTAS 2 designation, as AAEON’s special service assurance of wide temperature durability

          and reliability. This, in conjunction with the use of durable components throughout the duration of the testing, allows AAEON to enhance the
          longevity of its boards and systems.
