Embodiment Construction

[0051] In order to facilitate the understanding of the present invention, the testing machine and its testing method will be described more fully below with reference to the relevant drawings. The preferred embodiments of the testing machine and its testing method are given in the accompanying drawings. However, the testing machine and its testing methods can be implemented in many different forms and are not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the testing machine and its testing method more thorough and comprehensive.

[0052] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "ve...

Abstract

The invention relates to a test machine and a test method thereof. The test machine is applied to testing a circuit board. The test machine comprises a charging mechanism, a general test host, a first discharging mechanism, a flying probe test host, a feeding mechanism and a second discharging mechanism, wherein the general test host is used for electrically testing the circuit board so as to determine whether the circuit board is a qualified board or an unqualified board or an uncertain board and outputting first test result signals; the charging mechanism is used for conveying the circuit board to the general test host; and the first discharging mechanism comprises a first frame, a first material bench, a second material bench, a third material bench and a first transmission assembly. According to the test machine and the test method thereof, since the test process of the circuit board by the test machine does not require manual intervention, it is also unnecessary to manually schedule corresponding test information of the uncertain board according to printed information when the uncertain board is re-tested, and thus the test efficiency of the circuit board can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of circuit board testing, in particular to a testing machine and a testing method thereof. Background technique [0002] With the continuous improvement of PCB (Printed Circuit Board, printed circuit board) technology, the circuit board is gradually developing in a direction of thinner and lighter. The structure of the circuit board is becoming more and more complex, and the reliability requirements are getting higher and higher, so that the detection requirements of the circuit board are also getting higher and higher. When the pad size of the circuit board is below 2mil and the spacing between the solder joints is 6mil, the universal testing machine will not be able to test, and it can only be tested by the flying probe testing machine. Since the testing efficiency of the universal testing machine is higher than that of the flying probe testing machine, the universal testing machine is used for testing ci...
