Abstract
The utility model discloses a flash board for a test. The flash board comprises a board body, flash chips arranged on the board body, and an interface which is arranged on the edge of the board body and is connected with the flash chips so as to be connected with an upper computer, wherein the interface comprises pins used for selecting the flash chips. The flash board provided by the utility model can be used for efficiently testing flash.
Description
Technical field
The utility model relates to a kind of device for test flash chip.
Background technology
Along with the high speed in the fast development of current mobile storage technology and mobile storage market enlarges, the consumption of flash type storer is also increasing rapidly.The demand in market has expedited the emergence of out the enterprise of research and development, production and the application of large quantities of falsh chips.In order to guarantee chip work reliably and with long-term, need to test the chip of the flow of volume production or the chip of volume production.Because the output of current flash is huge, the test of flash storer/chip is very necessary efficiently.
The test of memory chip is not simple to notice that test one time is so simple, test before because the flash number of chips is fewer, is all that welding flash chip is tested on mainboard, not only inefficiency, and the very trouble that operates, also can produce harmful effect to mainboard.
Summary of the invention
In view of this, the purpose of this utility model is to develop independently integrated circuit board, to be used for carrying out the efficiently test of flash chip.
The technical solution adopted in the utility model is:
A kind of flash plate for test comprises plate body and array flash chip on plate body, and is arranged on the plate body edge and connects the interface of described flash chip to be used for being connected with host computer, and wherein interface contains the stitch that is useful on selection flash chip.
Can find out from technique scheme, according to the utility model, the integrated circuit board based on stand-alone development is connected in host computer by interface, thereby reduces frequent replacing flash chip to be tested to the impact of mainboard.Because an integrated circuit board can have multi-disc flash, thereby can significantly improve testing efficiency.Several different flash chip on integrated circuit board can be stated from simultaneously in addition, mutual compatibility test can be carried out.
Above-mentioned flash plate for test, described interface is the CN bus interface, correspondingly, described flash chip is connected with the CN bus interface by the CN bus.
Above-mentioned flash plate for test is characterized in that described flash chip has even number, and belongs in twos a passage.
Above-mentioned flash plate for test, described flash chip is connected on described plate body by socket or welded disc.
Description of drawings
Fig. 1 is the structure principle chart according to a kind of flash plate for testing of the present utility model.
Embodiment
With reference to explanation accompanying drawing 1, its left end represents the joint with host computer, and the line of upper lower limb represents signal wire, data line and control line, and middle horizontal line represents bus, and the square of center line horizontal line both sides represents the flash chip.
A kind of flash plate for test, it comprises plate body and array flash chip on plate body, and is arranged on the plate body edge and connects the interface of described flash chip to be used for being connected with host computer, wherein interface contains the stitch that is useful on selection flash chip.
Wherein plate body adopts PCB(Printed Circuit Board, printed circuit board), compact conformation, formed integrated circuit board better adaptability.
The joint of Fig. 1 left end is as the interface that is connected with host computer, for the plug connecting structure, than welded structure, changes sooner, and efficient is higher, and is less on the impact of mainboard.Simultaneously, integrated circuit board such as Fig. 1 according to predetermined port number, can expand to the number of coupling, the mount pad of 8 flash chips of 4 passages (chanel) as shown in Figure 1 (socket also can be understood as slot).
For simplified structure, described interface is the CN bus interface, and the fewer flash of this interface and wiring is complementary, and is relatively simple for structure, convenient wiring, and correspondingly, described flash chip is connected with the CN bus interface by the CN bus.
As shown in Figure 1, described flash chip has even number, and belongs in twos a passage.In order further to save the space, the socket of flash can two-sidedly be set.
Preferably, mate multiple application, described flash chip is connected on described plate body by socket or welded disc.
Claims (4)
1. flash plate that is used for test, it is characterized in that, comprise plate body and array flash chip on plate body, and be arranged on the plate body edge and connect the interface of described flash chip to be used for being connected with host computer, wherein interface contains the stitch that is useful on selection flash chip.
2. the flash plate for test according to claim 1, is characterized in that, described interface is the CN bus interface, and correspondingly, described flash chip is connected with the CN bus interface by the CN bus.
