Abstract
A thin type cell phone belongs to mobile communication technical field, comprising a casing, a printed circuit board arranged in the casing, an electronic circuit on the printed circuit board and the casing, keys, a displayer, a microphone, a receiver, a power supply, etc. Only one main board is arranged in the printed circuit board. The radio frequency circuit and the digital circuit in the electronic circuit are arranged at one side of the main board, while the keys are arranged at the other side of the main board. A ground isolated shield is adopted between the radio frequency circuit and the digital circuit, while the ground isolated shield is also adopted between the radio frequency ray and the digital ray. The printed circuit board has six layers, and the thickness is only 0.6mm. The utility model adopting the ALIVH-G technology is of small size, thin thickness, low production cost and more convenient portability and use. The utility model can be widely applied to mobile communication.
Description
Technical field
The utility model belongs to the mobile communication technology field, more specifically to the slimming of mobile phone and the improvement of miniaturization.
Background technology
According to market survey, the user is more and more higher for profile, the functional requirement of mobile phone.Therefore, mobile phone producer pays attention to the design of folding double screen and color screen more when the design mobile phone, and in order to satisfy user's needs, camera also joins on the mobile phone.This will ask factory identical with in the past bar phone width but arrange increasing components and parts in the mobile phone that length is very short.So initial folding cell phone all is the form that adopts two printed circuit board (pcb board) mainboards (two-sided cloth spare) to separate with keypad.But along with the increase of pcb board quantity, the thickness of mobile phone increases thereupon; And owing to also will install the metal plating support additional between two plates, this has just further increased the thickness of mobile phone.In addition, this many pcb boards and the structure that installs the metal plating support additional have increased the production cost of mobile phone simultaneously, return the user carry and use brings inconvenience.
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, provides that a kind of size is littler, thickness is thinner, and production cost lower, carry and use convenient slim mobile phone.
Summary of the invention
In order to achieve the above object, the utility model is installed in the printed circuit board (PCB) in the casing by casing, and the electronic circuit and button, display, receiver microphone and the power supply etc. that are installed on printed circuit board (PCB) and the casing are formed.Mainboard in the printed circuit board (PCB) has only one.Radio circuit in the electronic circuit and digital circuit are installed in the one side of mainboard.
Be tending towards the needs of frivolous conductization in order to satisfy the user for mobile phone, adopted the method for facecloth spare, one side is placed components and parts, and another side is the same special placement button of keypad then and originally.But the technology that domestic existing is produced pcb board can not satisfy above-mentioned needs, even reach the requirement of facecloth spare, can not make pcb board drop to desirable thickness.In view of above many reasons, selected the ALIVH-G technology for use.Be accomplished the design of single face fabric swatch.
Adopt the design of single face fabric swatch, utilize the ALIVH-G technology, radio circuit and digital circuit partly are put into mobile phone board with one side, the button part is at the mobile phone board another side, satisfied every performance index of mobile phone, and mobile phone board thickness is reduced significantly, made the mobile phone profile be tending towards miniaturization, the condition of the first-selected mobile phone of user is satisfied in slimming.This facecloth plate technique also can be widely used in the pcb board design of miniaturization.Traditional PCB design before following is selected two-sided fabric swatch (components and parts are all placed on the two sides) for use, adds independent keypad and metal-plated frame, the element of every placement is not high for space availability ratio like this, many rest positions are arranged, and make mobile phone very thick, do not reach the requirement of miniaturization.The position that these are idle fully utilizes, and the element on two sides is placed into one side, and keypad is removed, and reduces the integral thickness of mobile phone.
It is very many to use components and parts on the mobile phone, and the components and parts that adopt the single face fabric swatch need will reach 500 are put on the mainboard that area is 43.5mm * 78.5mm, and are quite high for utilization of space.If adopt existing BUILDUP making sheet technology, need at least 10 layers of ability to realize the single face fabric swatch, can not effectively reduce the thickness of mobile phone board.
Printed circuit board (PCB) can be 6 layers, and thickness has only 0.6 millimeter.The line because the ALIVH-G technology can be punched between random layer also can carry out the design in folded hole, hole, and more wiring space all is provided on every layer like this, in the position wiring that also can make full use of on each level under the hole, upper strata.Therefore six layers have only been used.
Adopt the ground Isolated Shield between radio circuit on the printed circuit board (PCB) and the digital circuit, also adopt the ground Isolated Shield between radio frequency line and the digital line.
Radio circuit part (emission, reception, PLL and VCO circuit) and digital circuit partly are placed on on the one side, and that leans on is very near, can influence radio frequency parameter.Adopt two-sided fabric swatch to be easy to solve this problem, but, adopt the single face fabric swatch just to have to radio frequency part and digital circuit partly are put into one side, therefore must consider the shielding problem, between radio frequency and digital circuit, adopt ground to isolate, and also adopt ground to isolate between radio frequency line and the digital line.
The utility model makes the thickness of simple pcb board reduce the thickness of 2.3mm than former pcb board (comprising the plating rack between the two-ply).Can utilize this advantage to make battery capacity increase, thereby prolong air time and stand-by time, satisfy present data service development and make the needs that power consumption is big.Simultaneously, the corresponding expense of having saved this part of the omission of the minimizing of pcb board quantity and plating rack.
Task of the present utility model comes to this and finishes.
The utility model provides that a kind of size is littler, thickness is thinner, and production cost lower, carry and use convenient slim mobile phone.It can be widely used in the mobile communication.
