As shown in Figure 3, the utility model photo-detector TO-CAN detailed test process of test macro that is coupled automatically is as follows:
(A) detector TO is installed on the test panel according to the station order, the register pin on the corresponding test box positioning seat of test panel is installed in the test box again, the locking snap close is closed the test chamber door, and material loading is finished.
(B) open testing software; parameters such as test odd numbers, test man's job number, product type are set; testing software calls corresponding device parameter according to product type; comprise: voltage fed voltage, current source supply electric current, light source light power, voltage table range, protection voltage, reometer range, protective current, test rate, instrument show setting, output port, power supply time-delay, light power meter wavelength, light decay depreciation, and the correlation parameter that is coupled automatically, motor initiation parameter, index judgement scope etc.Software can carry out initialization to testing apparatus according to the parameter that reads then, controls the motor playback simultaneously.
(C) carry out station according to test panel material loading state and select, choose the corresponding station that detector TO is housed, can begin test.Testing software reads the good station coordinate of calibration in advance, and control X, Y-axis slide unit move to the probe aperture top of No. 1 station, fall Z axle slide unit, make the probe on the slide unit touch thimble, are communicated with test circuit; Control the element top that U, V axle slide unit move to No. 1 station simultaneously, the fibre-optical probe on the W axle slide unit roughly is positioned at the lens center of detector TO.
(D) test electrical property: each reometer, voltage table begin to power up to element, parameters such as surveying work electric current, breakdown reverse voltage, dark current, and test result returned to computing machine, come out by the testing software interface display.If product through overaging, can show the variable quantity of each parameter of aging front and back according to the selection of testing process.
(E) test light performance: the optical attenuator optical gate is opened, source device output optical power, and light power meter reads current optical power value and returns to computing machine.If test value and setting value are not inconsistent, it is big or small that the computer control optical attenuator is regulated decay, until light stability in setting value.Voltage source is supplied with the suitable reversed bias voltage of PD, can begin automatic coupling, and idiographic flow is as follows:
(E1) thick coupling: U axle slide unit and V axle slide unit carry out from inside to outside spiral coupling according to the stepping of setting.When fibre-optical probe moved, the luminous power of vertically being injected by fibre-optical probe that detector TO receives also changed thereupon, and the response current of detector TO also changes thereupon simultaneously.Response current value and the UV coordinate figure of record every bit when the response current value surpasses limit value or spiral coupling area and exceeds setting range, namely stop coupling, and U, V axle slide unit are moved to the coordinate position of response current maximum.Whole process repeats twice, and the different current limit value of correspondence is looked for ray velocity with quickening respectively.
(E2) thin coupling: the response current that at first records initial position, response current after U axle slide unit moves a stepping and records movement along rectilinear direction according to the step distance of setting, if the corresponding electric current after mobile then continues to move along the initial movable direction greater than the response current of initial position, otherwise move toward reverse direction.Response current value and the U axial coordinate value of record every bit in the moving process, current value rises and then continues to move forward, and current value descends and then turns back to a current point position, stops coupling when mobile step number reaches setting value.V axle slide unit and W axle slide unit be coupling in this manner successively also.Whole process triplicate, each step distance is successively decreased, to improve measuring accuracy.
(F) after coupling is finished, according to peak response current value and optical power value calculated response degree parameter, and read the voltage magnitude of response wave shape by digital oscilloscope.Testing software carries out bad judgement according to the bound scope that arranges, and shows poor prognostic cause.
(G) after No. 1 station test was finished, Z axle slide unit rose, and probe leaves test panel, and testing software reads the station coordinate No. 2, and X, Y-axis slide unit drive probe and fibre-optical probe moves to position of components No. 2.Repeat above (C)-(F) step and carry out the test of No. 2 elements, and finish the test that all choose station by that analogy.
(H) after whole looping test was finished, probe rose, the motor playback.Snap close on the positioning seat is unclamped, take off test panel, finish blanking.As required test data is exported to electrical form or printing.
The beneficial effects of the utility model are as follows:
The utility model photo-detector TO-CAN test macro that is coupled automatically, with respect to the total man worker's test mode that extensively adopts at present, artificial loading and unloading have been adopted, automatically coupling, automatically the mode of test, because personnel's technical ability or emotion influence cause judging by accident, the problem of maloperation, and this system's operation is simple and easy when effectively having avoided the manual testing, reduce the technical ability requirement to the tester, had characteristics such as measuring accuracy height, test speed be fast.Automatically the speed that is coupled according to statistics is 3 times of speed of manually being coupled approximately, has improved production qualification rate and the test rate of detector TO greatly.Though and similar external full-automatic testing equipment also can reach high precision and two-forty, structure is very complicated, and price is very expensive, is not easy to maintenance and popularization.
The above is preferred embodiment of the present utility model only, is not for limiting protection domain of the present utility model.
