Abstract
A circuit board assembly includes a circuit board, a fixing device, and at least one color-changing piece. The circuit board includes a plurality of first contacts and second contacts opposite sides of the circuit board. The fixing device includes plurality of elastic contacts. The first contacts electrically connects to the second contacts, the at least one color-changing piece is located on and are electrically connected to the corresponding first contacts or the second contacts. When the circuit board is assembled at a predetermined position of the fixing device, the second contacts are electrically connected to the elastic contacts to form and provide an electric field, and the at least one color-changing piece changes color due to the electric field.
