A wafer is a crisp, often sweet, very thin, flat, light and dry biscuit, often used to decorate ice cream, and also used as a garnish on some sweet dishes. In the context of aerospace a wafer is a thin slice of semiconductor material, such as silicon, used in the production of integrated circuits and other electronic devices.
Wafers are used in a variety of applications, including the production of electronic components for avionics systems and other aircraft systems.
Here are a few examples of how wafers are used in the aerospace industry:
-
Avionics systems, which include everything from the navigation and communication systems to the flight control systems, often contain electronic components that are produced using wafers.
-
Some aircraft systems, such as engine control systems or fuel management systems, may also use electronic components that are produced using wafers.
-
Wafers may also be used in the production of sensors and other specialized electronic components used in aerospace applications.
Overall, wafers play a critical role in the production of many of the electronic components used in the aerospace industry, and they are an important part of the technologies that enable modern aircraft to function.
