Abstract
The invention provides an automatic test device, mainly applicable to the limit test of a circuit board to be tested. The automatic test device mainly comprises a main controller, a control unit and an adjusting unit, wherein one end of the control unit is electrically connected with the main controller for communicating with the main controller, the other end of the control unit is electrically connected with the circuit board to be tested for controlling the on and off of the circuit board to be tested, and the adjusting unit is electrically connected with the control unit for adjusting the resistance of a digital rheostat and communicated with the main control for performing limit test to the circuit board to be tested; if the test is completed, the circuit board to be tested is turned off, and if error occurs in the test, the circuit board to be tested keeps to be turned on. According to the automatic test device and the automatic test method provided by the invention, the digital rheostat is adopted, the change can be controlled by the process, the manual operation is avoided, the test process is completely and automatically finished, and the final result can be automatically recorded, so that the test efficiency is improved, and the manpower is also saved.
Description
Technical field
The present invention relates to a kind of proving installation and method, relate in particular to a kind of automatic testing equipment and method thereof that is applicable to internal memory etc. and carries out limit test.
Background technology
The limit (margin) test is a kind of mainly for internal memory, the test that the reliability of CPU etc. is carried out, make internal memory by regulating resistance, the corresponding operation level such as CPU departs from fiduciary level, moves specific testing software to confirm whether internal memory or CPU etc. can normally work.
At present mainboard limit test, all adopts manual adjustments rheostat mode, progressively changes voltage, until testing software produces mistake, and because of more than the every operation of testing software once at least needs half an hour, thus unusual waste of manpower time, and affect work efficiency.
Summary of the invention
In view of the above problems, the invention provides a kind of automatic testing equipment and method thereof.
In order to achieve the above object, the present invention has adopted following technical scheme: a kind of automatic testing equipment, be mainly applicable in the limit test of circuit board under test, and wherein, this device mainly comprises: master controller; Control module, its one end and this master controller are electrically connected, and to communicate with master controller, its other end and this circuit board under test are electrically connected, to control this circuit board under test start or shutdown; And adjustment unit, itself and control module are electrically connected, in order to the rheostatic resistance of numeral is adjusted, and communicate with master controller, so that this circuit board under test is carried out to limit test, if tested this circuit board under test shutdown, if this circuit board under test maintenance open state of mistake appears in test.
Preferably, the invention provides a kind of automatic testing equipment, utilize master controller that the resistance of this digital varistor is set, and the resistance of this setting is sent to this adjustment unit.
Again, the present invention also provides a kind of automatic test approach, is mainly applicable in the limit test of circuit board under test, and wherein, the method mainly comprises:
Step a. starts;
Step b. receives the instruction that master controller sends, and controls circuit board under test start;
Step c is adjusted the resistance of digital varistor;
Steps d. this circuit board under test is carried out to limit test;
If step e. has tested, this circuit board under test shutdown;

Again, the present invention also provides a kind of automatic test approach, is mainly applicable in the limit test of circuit board under test, and wherein, the method mainly comprises:
If step 205. has been tested, this circuit board under test shutdown;
If mistake appears in step 206. test, this circuit board under test keeps open state.
The invention provides a kind of automatic testing equipment and method thereof, adopt digital varistor, can be changed by process control, avoid manual operation, test process all completes automatically, and can automatically record net result, has not only improved testing efficiency, and has saved manpower.
