Abstract
The utility model discloses a flash memory tester which comprises a PCBA board, and a USB interface connected with a computer and a USB interface connected with an element to be tested are welded on the PCBA board. The utility model is characterized in that the USB interface connected with the computer is connected with an object to be tested through a switch and an USB interface of the object tobe tested is connected with the USB interface and then connected to the computer; and a flash memory test socket is further welded on the PCBA board, and an input interface of the flash memory test socket adopts a 24P wire-arrangement port and connected with a wire-arrangement interface of the flash memory of the object to be tested through the 24P arranged wires. The flash memory tester adopts aseparation-type structural design, so that different flash memory equipment can be directly picked, tested, produced in quantity, emptied, repaired and processed with technologies, no special testingequipment is needed to be produced additionally, the overlapping investment is reduced, and the production cost of the enterprise is greatly reduced.
Description
Technical field
The utility model relates to a kind of flash memory tester, specifically is a kind of USB flash disk that is applied to, flash card, and MP3, various production test, volume productions with digital electronic goods of memory function such as MP4 such as empty at the testing tool in the technology.
Background technology
Flash memory (Flash Memory) is a kind of long-life non-volatile storer, and it still can keep institute's data information stored under powering-off state, therefore is widely used in USB flash disk, flash card, MP3, MP4, digital camera etc. with the life closely-related digital electronic goods in the middle of.But the manufacturer of FLASH flash memory is numerous at present, and the quality quality is uneven, in order to produce the digital product that these have adopted the FLASH flash memory, the tester of test FLASH flash memory must be arranged.Traditional tester need expend certain financial resource and material resource and open the PCBA plate, because not general mutually, the how many kinds of scheme is arranged, the how many kinds of product just need be driven the how many kinds of tester, and after the scheme update, traditional tester has not had use yet, for manufacturer, this is the no small burden of pen.
The utility model content
At above-mentioned technical matters, but the utility model provides the flash memory tester of the various flash memories of a kind of compatibility test.
The technical solution adopted in the utility model is, a kind of flash memory tester, comprise the PCBA plate, be welded with USB interface that is connected with computer and the USB interface that is connected with components and parts to be tested on the PCBA plate, it is characterized in that, the USB interface that is connected with computer is connected with object to be tested by switch, the USB interface of object to be tested be connected to computer after USB interface links to each other; Also be welded with the flash memory test bench on the PCBA plate, the input interface of flash memory test bench adopts 24P winding displacement mouth, and is connected with the winding displacement interface of the flash memory of object to be tested by the 24P winding displacement.
The technical scheme that realizes the utility model purpose also further comprises:
Also be connected with pilot lamp between switch and the object to be tested.
The utility model adopts the separate type design, therefore can directly select test to various flash memory device, volume production empties, PROCESS FOR TREATMENT such as maintenance, do not need to produce in addition more special-purpose testing apparatus, reduce overlapping investment, greatly reduce the production cost of enterprise.
Description of drawings
Fig. 1 is the utility model principle of work block diagram.
Fig. 2 is the utility model circuit structure diagram.
Embodiment
Present flash memory manufacturer all needs their product is selected, test, and volume production empties, technologies such as maintenance, this just needs to use the flash memory tester.Traditional tester need expend certain financial resource and material resource and open the PCBA plate, because not general mutually, the how many kinds of scheme is arranged, and the how many kinds of product just need be driven the how many kinds of tester, and after the scheme update, needs again to develop new tester, causes the increase of cost.
The utility model is designed a kind of flash memory tester, it adopts a kind of PCBA plate of special use, be welded with usb 1 that is connected with computer and the USB interface 2 that is connected with components and parts to be tested on the plate, the usb 1 that is connected with computer is connected with object 11 to be tested by switch 3 and pilot lamp 4, the USB interface of object 11 to be tested be connected to computer after USB interface 2 links to each other.Also be welded with flash memory test bench 5 on the PCBA plate, the input interface of flash memory test bench 5 adopts 24P winding displacement mouth 8, and is connected with the winding displacement interface 10 of the flash memory of object 11 to be tested by 24P winding displacement 9.
Because two input interfaces of the utility model and element to be tested adopt USB interface and the general 24P 0.5MM spacing interface of flash memory, therefore go for the digital electronic goods with memory function of any model.
Use the selecting of electronic product of flash memory at all, test, volume production empties, and in the technologies such as maintenance, quite a few is that the USB interface that need be connected to computer is carried out.Between computer and element to be tested, designed a common power turn-on switch 3, so when switch conduction, just being equivalent to this product has been directly connected on the PC computer, therefore, the operation that tested object is relevant can directly be finished on computers, and this switch also solved the problem of the unsuitable hot line job of electronic product, specifically is meant the problem that picks and places flash memory here.For convenience indicating operating status has also designed a pilot lamp 4 as relay indicating light, and it can be convenient for people to the duty of this simple machine is observed and monitored with bright or go out whether represent duty.At switch 3 not under the situation of conducting, the winding displacement mouth 8 of flash memory test bench 5 and the winding displacement interface 10 usefulness 24P winding displacements 9 of object 11 to be tested are coupled together, press switch, pilot lamp 4 is bright, just can be according to relevant the selecting of tested object, test, volume production empties or the detail operations explanation of maintenance etc. is operated.
Claims (2)
1, a kind of flash memory tester, comprise the PCBA plate, be welded with USB interface that is connected with computer and the USB interface that is connected with components and parts to be tested on the PCBA plate, it is characterized in that, the USB interface that is connected with computer (1) is connected with object to be tested (11) by switch (3), the USB interface of object to be tested (11) be connected to computer after USB interface (2) links to each other; Also be welded with flash memory test bench (5) on the PCBA plate, the input interface of flash memory test bench (5) adopts 24P winding displacement mouth (8), and is connected with the winding displacement interface (10) of the flash memory of object to be tested (11) by 24P winding displacement (9).
