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.
Claims20
A circuit board assembly comprising:
- a circuit board for supporting electronic components;
- a fixing device for holding and securing the circuit board, the fixing device comprising:
- a main body for holding the circuit board;
- and
- a cover rotatably connected to the main body for securing the circuit board to the main body;
- and
- a color-changing layer located on at least one of the circuit board and the cover, wherein the color-changing layer can change color under pressure, and when the circuit board is assembled at a predetermined position relative to the fixing device and is secured to the main body by the cover, the cover exerts pressure on portions of the circuit board causing changes to the color of the color-changing layer.
A circuit board assembly comprising:
- a circuit board comprising a plurality of circuit contacts at one side of the circuit board;
- a fixing device that holds and secures the circuit board, the fixing device comprising:
- a main body for holding the circuit board;
- an at least translucent cover rotatably connected to the main body for securing the circuit board to the main body;
- and
- a plurality of elastic contacts, each elastic contact located on the main body and corresponding to one of the circuit contacts;
- and
- a color-changing layer, wherein the color-changing layer comprises a mixture of piezoelectric material and electrochromic material and is located on the cover, the circuit board or the circuit contacts, when the circuit board is assembled at a predetermined position relative to the fixing device, the circuit contacts are aligned with and electrically contacted to the corresponding elastic contacts, the cover resists against and exerts pressure against portions of the circuit board to form protruding points on the color-changing layer at the positions corresponding to the elastic contacts, the color-changing layer generates an electric field and changes color.
