Abstract
The utility model discloses a device used for an automatic test of a crystal bar resistor comprising a support, a long pressing plate, 36 probes, and a data scanner. The support is provided with a slide rail. The long pressing plate is disposed on the slide rail, and is provided with 36 installation holes. The probes are disposed in the installation holes, and are connected with the data scanner. The data scanner comprises a voltmeter, an ammeter, and a data acquisition unit, which are connected together. The long pressing plate is made of metal, and is provided with circular pressing blocks, the number of which is in a range from 1 to 3. The device used for the automatic test of the crystal bar resistor is advantageous in that the traditional crystal bar resistor measurement method can be changed from the two-probe manual piecewise test into the multi-probe simultaneous automatic measurement, and therefore the test speed of the crystal bar and the production efficiency can be improved, and at the same time, the errors of the manual test can be reduced, and the test accuracy can be improved.
Description
Technical field
The utility model belongs to field of semiconductor manufacture, is suitable for semiconductor cooler, particularly a kind of for the crystal bar resistance device of test automatically.
Background technology
After crystal bar is made, need test crystal bar resistance value.Crystal bar resistance test is to adopt manual mobile test the piecemeal of two probes for a long time: on crystal bar testing jig guide rail, plastic presser plate is housed, 2 probe (see figure 1)s are installed in plastic presser plate.Crystal bar is divided into some sections by 10 millimeters of intervals from afterbody to head, and when measurement, crystal bar, from afterbody, is measured two points for every section.Complete one section of every survey, plastic presser plate and two probes need move 10 millimeters (mobile one sections), measuring resistance piecemeal several times, resistance value shows at voltage table, manually carries out record.There is following shortcoming in this method of testing:
1. probe, by moved by hand, is measured a crystal bar and will be moved 35 times, and 1 resistance value of every measurement, needs manual record 1 time, then input computer.Waste time and energy, efficiency is lower.
2. because probe is by moved by hand, each mobile distance is not quite identical.While measurement, two probes need to contact with crystal bar completely simultaneously, and plastic presser plate is lighter, need in plastic presser plate, make with hand probe contact crystal bar surface completely when measurement, and pressure varies.Inevitably bring some personal errors, affected the accuracy of crystal bar resistance measurement.The resistance value discreteness recording on a crystal bar is larger.
Utility model content
The purpose of this utility model is to provide a kind of manual testing of minimizing error, improves the device of automatically testing for crystal bar resistance of measuring accuracy.
For solving the problems of the technologies described above, the utility model, for the crystal bar resistance device of test automatically, comprising: support is provided with slide rail on described support; Long pressing plate, described long pressing plate is arranged on described slide rail, has mounting hole at described long pressing plate; Probe, described probe is arranged in described mounting hole; The quantity of wherein said probe and described mounting hole is 36; Data scanning instrument, described data scanning instrument is connected with described probe.
Described data scanning instrument comprises interconnective voltage table, reometer and data acquisition unit.
On described long pressing plate, round briquetting is installed.
The quantity of described round briquetting is 1～3.
The material of described long pressing plate is metal.
The device that the utility model is tested automatically for crystal bar resistance changes traditional crystal bar resistance measurement method into multiprobe measurement automatically simultaneously by manual mobile test the piecemeal of two probes, test speed and the production efficiency of crystal bar are improved, the error that has simultaneously reduced manual testing, has improved measuring accuracy.

Embodiment
The device of the utility model being tested automatically for crystal bar resistance below in conjunction with accompanying drawing is described in further detail.
As shown in Figure 1 and Figure 2, the utility model, for the crystal bar resistance device of test automatically, is installed the long pressing plate 2 of metal on the slide rail 4 of support 5, on the long pressing plate 2 of metal, opens 36 holes, and 36 probes 1 are installed in it.Circle briquetting 6 is installed on the long pressing plate 2 of metal, (can determine 1～3 round briquettings 6 are installed according to the length of crystal bar 3 to be measured).When test, circle briquetting 6 place's horizontalitys, rely on gravity that every probe 1 is contacted completely with crystal bar to be measured 3 surfaces.Increase data scanning instrument simultaneously, on primary voltage table and reometer basis, increase data acquisition unit, by programming data collector, the resistance value recording is inputted to computer automatically, the output of resistance value is completely automatic, manually without operation.
The device that the utility model is tested automatically for crystal bar resistance changes traditional crystal bar resistance measurement method into multiprobe measurement automatically simultaneously by manual mobile test the piecemeal of two probes, test speed and the production efficiency of crystal bar are improved, the error that has simultaneously reduced manual testing, has improved measuring accuracy.
Below the preferred embodiment of the utility model having been created illustrates, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all modification being equal to or replacement under the prerequisite without prejudice to the utility model creative spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
