Abstract

The invention relates to a frame type keyboard circuit film with a zigzag air duct and a manufacturing method of the framework type keyboard circuit film. The frame type keyboard circuit film comprises two insulating films and a spacer located in the middle layer, wherein ventilation through holes of the spacer and the adhesive pattern layers on the upper surface and the lower surface of the spacer are utilized to form a splicing ventilation channel which is ventilated outwards and extends to the air bag chamber of the key region in a 3D zigzag mode. In a structural example, the circuit film further has a 3D tortuously extending loop type air sac air duct. The frame type keyboard circuit film achieves the effect of enhancing the waterproof performance on the basis of thinning and light weight. In a manufacturing example, frame holes of the frame type keyboard circuit film and the outline of the frame can be formed after the two insulating films are laminated.

Description

technical field [0001] The invention relates to the technical field of keyboards, in particular to a frame-type keyboard circuit film with meandering air passages and a manufacturing method thereof. Background technique [0002] The keyboard is a kind of man-machine interface, as a medium and dialogue interface for transmitting and exchanging information between people and computers, usually at least able to input character information such as A-Z, and is an important part of the computer system. The keyboard realizes the transmission of information input to the computer by pressing a button, for example, a mainframe computer, a notebook computer and even some tablet computers all have a keyboard design. Therefore, the keyboard contains the contact electrodes for key transmission and the circuit structure for connecting the electrodes. The early keyboard was a mechanical keyboard structure, which was thicker overall, and then gradually transformed into a thin-film circuit s...
