Based on above-mentioned mobile terminal hardware configuration, communication apparatus structure, propose the present invention and each embodiment of pad structure shared, Shared pad structure is a part for mobile terminal.

In an embodiment of the present invention, the pad sharing structure is including sharing pad 1 and multiple non-common pads 2, many The parameter of individual non-common pad 2 is differed, and multiple non-common pads 2 are distributed centered on the shared pad 1, to realize Installation of the different components and parts on shared pad 1 and different non-common pads 2.

The pad sharing structure of the present invention is mainly used on pcb board, and pcb board is printed circuit board (PCB), is provided with collection Become the thin plate of circuit and other electronic building bricks.Pcb board by complicated circuit connection between part and part, through careful neat After planning, lead to overetched mode and concentrate on one piece of plank, main support of the electronic components when installing with interconnection is provided Body, is the indispensable fundamental parts of all electronic equipments.Electronic equipment is using after printed board, consistent due to similar printed board Property, so as to the mistake of artificial wiring is avoided, and can achieve electronic devices and components inserting or attachment, automatically automatic tin soldering, inspection automatically Survey, it is ensured that the quality of electronic equipment, improve labor productivity, cost is reduced, and be easy to maintenance.

It is divided into according to wiring board number of plies pcb board：It is divided into single sided board, dual platen and multi-layer sheet.Single sided board is most basic PCB Plate, one side wherein concentrated by part, and wire then concentrates on another side.Because wire only have one side, all wiring between can not intersect and Single sided board must be caused to have many strict restrictions in designed lines around path alone.Dual platen is that two sides has wiring Pcb board, and will use two sides wire, need to be attached the circuit between two sides by guide hole.Guide hole be on PCB, Full of or coated with metal duck eye, it can be connected with the wire on two sides.Because dual platen wire can be detoured by guide hole Another side, wiring intermeshes, and is suitable for complicated circuit.Multi-layer sheet is that the superposition of polylith single or double plate is used, to increase Plus layout area.Make with one piece of dual platen that internal layer, two pieces of single sided boards make outer layer or two pieces of dual platens are made internal layer, two pieces of single sided boards and made The pcb board of outer layer, by alignment system and adhesive material alternately together and conductive pattern is interconnected by design requirement Pcb board just become four layers, also referred to as six layers of pcb board, multi-layer PCB board.It is independent which floor the number of plies of plank just represents Wiring layer, the usual number of plies is all even number, and includes outermost two-layer.

In order to components and parts are fixed and attached on pcb board, typically around the fairlead of pcb board, Copper Foil conduct is mounted Pad, the pin of components and parts is fixed to components and parts on pcb board with scolding tin, while with printed conductor 3 not through after fairlead Couple together with the Copper Foil between pad, you can realize components and parts are connected and fixed on pcb board.But it is that typically in circuit In, wire can be equal to antenna to a certain extent, and can collect electric charge (as the charged particle that plasma etching is produced) causes electricity Position raises.Antenna is longer, and the electric charge of collection is also more, and voltage is higher.Certain part is only connect to the grid circuit of MOS, high Voltage may puncture thin gate oxide, make circuit malfunction, that is, produce " antenna effect ".With the development of Technology, grid Size less and less, the number of plies of metal is more and more, occur antenna effect probability bigger.Fig. 3 is refer to, is existed at present During circuit design, different components and parts are commonly designed the pad of exclusive use, and two adjacent performance identical pads are generally used Printed conductor 3 is attached, while in order to keep components and parts safe spacing, and cause to connect the print of two performance identical pads Wire processed 3 is longer, and this longer printed conductor 3 can be produced antenna effect and high-frequency signal is formed and interfere equivalent to antenna, and then Impact circuit performance.

Fig. 4 is refer to, the pad sharing structure of the present invention is shared by multiple for performance identical pads are set to one Pad 1, and around the non-common pad 2 of different parameters is arranged on centered on sharing pad 1, shared pad 1 and multiple Need not connect between non-common pad 2, there is no unnecessary printed conductor 3, antenna effect can be avoided, it is ensured that circuit performance. While the multiple pads of performance identical are set to a shared pad 1, the space of pcb board can be saved, improve the utilization of pcb board Rate.When components and parts are installed, it is only necessary to which, by a pin of components and parts through the fairlead for sharing pad 1, another pin is worn Cross the fairlead of pad corresponding with its parameter, you can realize the installation of the components and parts, it is to avoid first device of different performance parameter The mistake of part is installed, and prevents pad short circuit.Specifically, Fig. 5 refer to, when carrying out the installation of resistance 5, a pin of resistance 5 is installed On shared pad 1, another pin is on non-common pad 2 corresponding with 5 parameter of resistance.

Further, the shared pad 1 is low pressure of high-pressure side, the multiple non-common pads 2 for different magnitudes of voltage End.

In a preferred embodiment of the invention, shared pad 1 is set to high-pressure side, multiple non-common pads 2 are set to The low-pressure end of different magnitudes of voltage, selects magnitude of voltage corresponding with its performance parameter according to the performance parameter of components and parts itself during use Low-pressure end installed.It should be noted that when active components and parts are installed, needing to be installed to the positive pole of active components and parts Shared pad 1, negative pole is installed to non-common pad 2, and does not have this restriction for passive component.Specifically, in a pad In sharing structure, including a high-pressure side A and two low-pressure ends B, C.Wherein high-pressure side A voltage is 24V, two low-pressure ends B, C Voltage be respectively 10V and 4V, then the pressure reduction between AB be pressure reduction between 14V, AC be 20V.An existing electric capacity and resistance 5, The rated voltage of wherein electric capacity is 14V, and the rated voltage of resistance 5 is 20V.Then electric capacity can only be installed between AB or by electricity Resistance 5 is installed between AC, rated voltage of the pressure reduction of 20V more than electric capacity 14V between AC, and electric capacity is installed between AC and may be burnt Bad, and between AB 14V pressure reduction less than resistance 520V rated voltage, resistance 5 be installed between AB may not normal work, Even there is idle situation.In other embodiments, it is also possible to which shared pad 1 is set to low-pressure end, multiple non-common Pad 2 is set to the high-pressure side of different magnitudes of voltage.Now when active components and parts are installed, need to pacify the positive pole of active components and parts Non-common pad 2 is attached to, negative pole is installed to shared pad 1, and does not have this restriction for components and parts for no reason at all.Because on components and parts Load voltage value be to determine, and user is readily available, all shared pads 1 and non-common pad 2 use voltage as ginseng Number embodiments, user using when can be perfectly clear know that components and parts should be installed on that non-common pad 2, people Property degree height.

Further, the quantity of the non-common pad 2 is two.

In one embodiment of the invention, the quantity of non-common pad 2 is set to two, you can support two kinds of different models The installation of components and parts.Because pcb board is by complicated circuit connection between part and part, after careful neat planning, lead to Overetched mode is concentrated on one piece of plank.Therefore the limited area of pcb board, and this pad sharing structure is in order to prevent difference The mistake of performance parameter components and parts is installed, and can only install a type of components and parts every time, is also implied that every time only using one Non-common pad 2.Consider this kind of situation, the quantity that non-common pad 2 is arranged is more, the more space of pcb board can be taken, is carried High cost.But more non-common pad 2 can be set in the embodiment of normal work in other such as testing elements Quantity, so as to not tested by the components and parts of model.Specifically, have respectively rated voltage parameter for 10V, 12V, 14V, Six resistance 5 of 16V, 18V and 20V need to test its service behaviour, and pad sharing structure now arranges a shared pad 1 With six non-common pads 2, and the voltage performance parameter of a shared pad 1 and six non-common pads 2 be respectively 36V, Six resistance 5, during test, are installed to corresponding with its voltage parameter by 26V, 24V, 22V, 20V, 18V and 16V successively respectively Non-common pad 2 on, to realize its testing requirement.

Preferably, described two non-common pads 2 are located at the opposite end for sharing pad 1, and the company of its central point respectively Line is through the central point of shared pad 1.

Specifically refer to Fig. 4, two non-common pads 2 by share pad 1 centered on be distributed in 1 two ends of shared pad with Shared pad 1 is in alignment.This linear pad had not only facilitated positioning processing but also had facilitated the installation of components and parts, while being also convenient for Any position for being arranged in pcb board, take pcb board space little.

Further, described two non-common pads 2 are located at the vertical two ends for sharing pad 1, one of non-co- respectively With the central point of pad 2 and the line of 1 central point of shared pad perpendicular to another non-common pad 2 central point and shared weldering The line of 1 central point of disk.

In further technical scheme, Fig. 6 is refer to, two non-common pads 2 are located to be located at respectively and share weldering On the vertical two ends of disk 1, right-angle structure is cooperatively formed with shared pad 1.The pad arrangement of this right-angle structure, is easy to and other yuan Device arranges in pairs or groups to form rectangular configuration, makes the compact conformation of whole pcb board, save space.

Further, around the shared pad 1 and multiple non-common pads 2, silk-screen 4 is provided with.

Specifically, it is provided with around each pad and bond pad shapes identical silk-screen 4, each pad is being demarcated Also isolation is formed between two adjacent pads while differentiation.Isolation barrier during welding because of silk-screen 4 is acted on, and even stannum is not allowed Easily between two neighboring pad, short circuit is formed, reach the effect of continuous tin prevention.

Preferably, the spacing between the shared pad 1 and multiple non-common pads 2 is equal and equivalently-sized.

Understandably, shared pad 1 and multiple non-common pads 2 are set to spacing equal, equivalently-sized can be By being changed without in the case of other processing unit (plant)s, all pads are processed, improve working (machining) efficiency.Consider different pads The components and parts of installation are inconsistent, and the difference of components and parts to further relate to pin size inconsistent, so in order to as much as possible and Hold different components and parts, the fairlead of pad can be arranged according to large-sized components and parts, in order to dissimilar components and parts Install.
