Abstract
A circuit board assembly includes a circuit board, a fixing device, and a color-changing layer. The fixing device is capable of holding and securing the circuit board and includes a main body and a cover. The cover is rotatably hinged to the main body. The color-changing layer is located on either or both of the circuit board and cover. When the circuit board is assembled at a predetermined position of the fixing device and is secured on the main body by the cover, the cover exerts a pressure to form protruding points on the color-changing layer at the positions corresponding to the elastic contacts, the color-changing generates an electric field and changes color, which is easily and quickly verifiable by a worker.
