Problems solved by technology
Since the connecting board must be used by curling and bending, the connecting board is easy to break
In addition, the gold finger on the side keypad of this mobile phone, because the front finger is flush with the back finger, when bent, the stress point appears at the opening of the protective film, that is, at the connection end between the back finger area and the protective film. The opening of the protective film has glue flow after lamination, and a cut with height difference is formed at the junction of glue flow and electroplating. When bending, the cuts on both sides are prone to breakage

The invention discloses a bending-resistant mobile phone side key panel, which comprises a golden finger end, a switch end and a connecting board used for connecting the golden finger end and the switch end. The face and the back of the golden finger end are both provided with golden fingers. The bending-resistant mobile phone side key panel is characterized in that the connecting board, the golden finger end and the switch end are arranged on one plane, wherein the golden finger end is arranged on the front side of the switch end, and the connecting board is a U-shaped flexible circuit board. The invention can be used without being rolled into a three-dimensional U shape, and has excellent bending resistance.
Description
technical field [0001] The invention belongs to the technical field of flexible circuit board structure design, and in particular relates to a side key board of a bending-resistant mobile phone. Background technique [0002] Flexible printed circuit boards (FPC for short) have the advantages of high wiring density, light weight, thin thickness, small wiring space restrictions, and high flexibility. communication products, displays and consumer electronics and other fields. [0003] The flexible circuit board generally includes gold fingers for electrical connection with the outside world. When installed and used, it is generally necessary to bend the flexible circuit board to electrically connect it with the external circuit. In the existing design, the length of the front and back of the gold finger at the finger part is the same. Compared with the rest of the printed circuit area, the gold finger area has obvious differences in hardness and strength, and also has an obvio...
