Embodiment Construction

[0019] Examples of the present invention are figure 1 What is shown is a keyboard, which includes a plurality of keys 13 , a base plate 11 , a membrane assembly 12 and a circuit board 16 . The film assembly 12 is disposed on the seat plate 11 . The circuit board 16 is disposed between the base plate 11 and the key 13 , and the circuit board 16 has a chip 14 . The chip 14 is ground to a specific thickness Y without damaging the circuit structure of the chip, and is mounted on the circuit board 16 by wire bonding.

[0020] In this embodiment, the film assembly 12 and the circuit board 16 are electrically coupled through the connection parts X and X'. The film assembly 12 has a plurality of switch assemblies (not shown), and each switch assembly corresponds to a button. When the switch When the component senses the touch of the key 13, it will send a key signal to the chip 14. The chip 14 is a keyboard controller (controller), which is used to transmit the key signal to an inf...

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 thinner and smaller electronic products, the size of the keyboard is getting thinner and 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 also relatively compressed. Therefore, the size of each keyboard component 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 to work independently, and can communicate with other keyboards by means of a PS / 2, USB interface or wireless transmission interface. The computer does the data entry. Since the thickness of the keyboard control chip will affect the thickness design of the keyboard itself, if the thickness of the keyboard control chi...
