Abstract
The utility model relates to a main board of a mobile communication terminal. The main board comprises a rigid printed circuit board, and a shield cover arranged on the rigid printed circuit board. The main board is characterized in that a flexible printed circuit board is connected with one side of the rigid printed circuit board; and the flexible printed circuit board includes all of test points desired for the rigid printed circuit board, and is folded reversely and mounted on the shield cover of the rigid printed circuit board. Compared with the prior art, the main board has following advantages: (1) the design space of the rigid printed circuit board is reduced, which facilitates the development of smaller mobile communication terminal main board; (2) the rigid printed circuit board can have easier design and more uniform wiring; (3) the test coverage percentage is improved, and almost all of the desired test points can be extracted and placed on the flexible printed circuit board; and (4) the wiring space of the rigid printed circuit board can be increased to reduce interference among wires.
Description
Technical field
The utility model relates to a kind of mainboard of mobile communication terminal.
Background technology
Along with the function of mobile communication terminal (as mobile phone, PDA etc.) is more and more, the particularly popularization of future mobile communications terminal makes in actual production process, need be more and more to the project that the mainboard of mobile communication terminal is tested.Yet for the needs of appearance design, it is little and compact generally to require the overall dimensions of the mainboard of mobile communication terminal to relate to ground.The mainboard of existing mobile communication terminal only comprises the printed circuit board of a rigidity usually, the printed circuit board of this piece rigidity need all design into all functional circuits, and, the test point that also needs to reserve all functions when the printed circuit board of design rigidity, how placing increasing test point in the printed circuit board of more and more littler rigidity becomes the direction that each portable terminal hardware relates to department's effort.
At present, most of hardware designs department adopts and dwindles test point size and spacing, even deletes some less important test points and guarantee that enough spaces leave the element on the mobile communication terminal mainboard for.But there is following problem in this design: at first, dwindle test point size and spacing, need to use the littler probe of size to test, not only price is more expensive, the life-span is shorter for little probe, and false failure rate also compares higher in the actual production test; Secondly, delete some less important test points, make test coverage reduce; Though the non-key device of some device, if these devices without test, are difficult to pinpoint the problems in the subsequent production process, this directly causes the repair rate of mobile communication terminal secondary function to increase.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of circuit the simple mainboard that also can effectively guarantee the mobile communication terminal of mobile communication terminal motherboard design space and test coverage at above-mentioned prior art.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the mainboard of this mobile communication terminal, comprise a rigid printed circuit boards, this rigid printed circuit boards is provided with screening cover, it is characterized in that: a side of described rigid printed circuit boards is connected with a flexible circuit board, this flexible circuit board comprises the needed test point of all described rigid printed circuit boards, and the reverse bending of described flexible circuit board is mounted on the screening cover of described rigid printed circuit boards.
Utilize the Rigid Flex technology of comparative maturity, utilize the flexible circuit board above the Rigid Flex, needed test point is all drawn on the rigid printed circuit boards with mobile communication terminal, utilize the bendable folding endurance of flexible circuit board simultaneously, flexible circuit board is attached to exactly by the reverse bending of certain technology controlling and process on the screening cover of rigid printed circuit boards of mobile communication terminal, the size of flexible circuit board can change with the difference of screening cover size on the rigid printed circuit boards of mobile communication terminal.Because of being drawn, the point that all need be tested on the rigid printed circuit boards of mobile communication terminal is placed on the flexible circuit board simultaneously, flexible circuit board just has enough spaces rationally to place above-mentioned test point, therefore test point spacing and test point size can be amplified, even in assembling process, produce certain error, also can not increase false failure rate.
For guaranteeing the accuracy of flexible circuit board paste position, can be left to few two location holes on flexible circuit board, assembly line anchor clamps that can design specialized guarantee its accuracy: utilize on the rigid printed circuit boards of mobile communication terminal by location hole and the accuracy and the consistency that guarantee the flexible circuit board paste position by anchor clamps of the location hole on the flexible circuit board.
For the mainboard that makes mobile communication terminal has better antistatic property, described flexible circuit board sticks on the screening cover of described rigid printed circuit boards by the conduction adhesive paper, and the location for paste ground connection of described flexible circuit board.
Compared with prior art, advantage of the present utility model is:
1, save rigid printed circuit boards the design space, help developing littler mobile communication terminal mainboard;
2, the design of rigid printed circuit boards can be simpler, and cabling is more unified;
3, can increase test coverage, the test point of nearly all needs can be extracted and be placed on the flexible circuit board;
4, can increase the spacing of cabling in the rigid printed circuit boards, make between circuit and disturb still less;
5, can develop unified test probe and guarantee the consistency of testing.
