Electronics Technology is the application of scientific theories and principles in the design, production, installation, testing, service, use, and control of electrical and electronic parts, equipment and systems. Electronics technology is used across all industries, including commercial, residential, and industrial. Technologists normally work as members of 'engineering teams' in applied design, product development, installation, maintenance, manufacturing, production, or operations. Technologists may also work in technical services including field engineering, customer support, marketing, and sales.
