A product teardown, or simply teardown, is the act of disassembling a product, such that it helps to identify its component parts, chip & system functionality, and component costing information. For products having 'secret' technology, such as the Mikoyan-Gurevich MiG-25, the process may be secret. For others, including consumer electronics, the results are typically disseminated through photographs and component lists so that others can make use of the information without having to disassemble the product themselves. This information is important to designers of semiconductors, displays, batteries, packaging companies, integrated design firms, and semiconductor fabs, and the systems they operate within.
