Embodiment Construction

[0018] Examples of the present invention figure 1 What is shown is a keyboard, which includes a plurality of keys 13, a board 11, a membrane component 12 and a circuit board 16. The thin film component 12 is arranged on the seat plate 11. The circuit board 16 is disposed between the base plate 11 and the button 13, and the circuit board 16 has a chip 14. The chip 14 is reduced to a specific thickness Y by grinding, without destroying the circuit structure of the chip, and is placed on the circuit board 16 by wire bonding.

[0019] In this embodiment, the membrane component 12 and the circuit board 16 are electrically coupled through the connecting portions X and X'. The membrane component 12 has a plurality of switch components (not shown), and each switch component corresponds to a button. When the component senses the touch of the button 13, it sends a button signal to the chip 14. The chip 14 is a keyboard controller (controller) for transmitting the button signal to an informa...

Abstract

A method for making keyboard and flexible circuit board thereof. Said keyboard consists of plurality of keys, a base board and a circuit board which is set between base board and keys, the circuit board has a chip set on circuit board, the thickness of chip can be reduced to a specified thickness by grinding and set on circuit board by lead bounding.

Description

Technical field [0001] The invention relates to a keyboard, in particular to a keyboard with an ultra-thin size. Background technique [0002] With the trend of lighter, thinner, shorter and smaller electronic products, the size of the keyboard has gradually become thinner to meet the visual and portable needs of users. When the size is reduced, the space occupied by each component in the keyboard is relatively compressed. Therefore, the size of each keyboard assembly will affect the overall thickness of the keyboard. In a notebook computer with a "separate" keyboard, the keyboard itself has a keyboard control chip and can be separated from the notebook computer casing for independent operation, and can be connected to other computers by means of a PS / 2, USB interface or wireless transmission interface. The computer does data input. Since the keyboard control chip has a thickness that will affect the thickness design of the keyboard itself, if the thickness of the keyboard contro...
