Embodiment 1

[0021] figure 2 It shows a PCB used for the side key of a mobile phone. There are first positioning holes 201 and second positioning holes 202 oppositely arranged on the PCB, and the positioning holes are all elliptical. One side of the first positioning hole 201 and the second positioning hole 202 is provided with a first grounding pad 211 and a second grounding pad 212, and the other side of the first positioning hole 201 and the second positioning hole 202 is provided with a third grounding pad. The pad 213 and the fourth ground pad 214, the third ground pad 213 and the fourth ground pad 214 are provided with a controller pad 221 in the middle, and the edges of the third ground pad 213 and the fourth ground pad 214 are respectively Falling into a rectangle with a width of 0.75 mm and a length of 1.8 mm, that is, the areas of the third ground pad 213 and the fourth ground pad 214 are smaller than the area of ​​the above rectangle.

[0022] In this example, if figure 2 As...

Embodiment 2

[0026] This embodiment provides a mobile phone, which includes a mobile phone case, a controller and a side key. The mobile phone case is provided with an accommodating groove, and the side key is arranged in the accommodating groove. The mobile phone also includes the PCB in Embodiment 1, and the PCB is arranged In the mobile phone case; the fixing part on the side key is plugged and fixed with the PCB through the positioning hole, the solder pads on the PCB and the solder spots on the side key are welded in one-to-one correspondence, and the controller pad 221 is also electrically connected to the controller.

[0027] The controller will generate corresponding action commands according to the detected action of pressing the side button to control the action of other components in the mobile phone. For example, the side button is a side button with a screen lock function. When the controller detects that the side button is pressed, the controller controls the display to unlock...

Abstract

The invention discloses a PCB for a mobile phone side key and a mobile phone. The PCB is provided with a first positioning hole and a second positioning hole that are opposite, one side of the first positioning hole and the second positioning hole is provided with a first grounding pad and a second grounding pad, the other side of the first positioning hole and the second positioning hole is provided with a third grounding pad and a fourth grounding pad, a controller pad is arranged between the third grounding pad and the fourth grounding pad, and the edges of the third grounding pad and the fourth grounding pad respectively fall into a rectangle with a width of 0.75mm and a length of 1.8mm. The PCB for the mobile phone side key effectively improves the deadlocking phenomenon during the first pressing in the process of mobile phone assembling and improves the assembling efficiency of workers.

Description

technical field [0001] The invention relates to a PCB used for side keys of a mobile phone and a mobile phone. Background technique [0002] With the development of mobile communication technology, mobile phones are playing an increasingly important role in people's life and work. Nowadays, the screens of mobile phones are getting larger and fewer buttons. Generally, the buttons of the mobile phone are arranged on the side of the mobile phone casing to save space. For example, some mobile phones have volume adjustment buttons, mobile phone power-on / off buttons, screen lock buttons, and the like. The important component to realize the function of the side key of the mobile phone is the PCB electrically connected to the side key of the mobile phone and the controller. [0003] In the existing technology, such as figure 1 As shown, the side button PCB includes 4 rectangular ground pads 101, 1 controller pad 102 and 2 circular positioning holes 103. After soldering the mobile...
