documentation;terminology
A teardown report is a summary of disassembling a product.From Wikipedia:A product teardown, or simply teardown, is the act of disassembling a  product, such as a television set, to identify its component parts and  functions. 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.
