Outlined the important role of QJ2940-97 “Technical Requirements for Rehabilitation and Modification of Aerospace Electronic and Electrical Products” in the development of aerospace electronic and electrical products, and analyzed and explained the meanings of several concepts such as rework, repair, and modification that are easily confused in the standard. The standards for repair and modification requirements (constraints), the content of the preparation of repair and modification process regulations, and the eligibility criteria for the repair and modification of several items such as component removal, printed pad and printed conductors were further studied. Explain that with a view to a unified understanding, strict implementation of standards to promote the quality of aerospace electronic and electrical products.
