Problems solved by technology

But at the same time, since the flying probe tester only has 4 probes, the computer can only measure the electrical connection relationship between the designated terminal and the other 3 terminals every time the computer sends a test command. The state of the circuit network usually requires the computer to repeatedly send multiple test instructions. The test control process is complicated, which not only brings difficu

Embodiment

[0027] Such as figure 2 As shown, there are only 2 slots on the H001 backplane to be tested, and there are 6 terminals in each slot. The entire H001 backplane has 12 terminals in total, including 5 circuit networks. From figure 2 It can be seen from the figure that if the terminal numbers of the H001 backplane are arranged in order from top to bottom and then from right to left, the No. 1 and No. 2 terminals are connected to the same circuit network, and No. 3 and No. 9 terminals are connected to the In the same circuit network, terminals No. 4, 5, 7 and 8 are connected to the same circuit network, terminals No. 6, 10 and 11 are connected to the same circuit network; terminal No. 12 is an isolated terminal, which itself constitutes a circuit network.

Abstract

The invention provides a backplane test method, which comprises the following steps that: a computer sends a test instruction, and a test control module controls interface adapters connected on all terminals of a backplane to be tested to carry out test according to a control instruction. The method adopts a process control mode of avoiding repeated testing, and the computer can test and obtain test data of one circuit network in the backplane to be tested after sending the test instruction every time. Therefore, the backplane test method simplifies the test control process, improves the execution efficiency of the computer, simultaneously avoids repeated testing on the tested terminals, further shortens the backplane test time, improves the test efficiency, and meets the needs for bulk testing.

Description

technical field [0001] The invention relates to the field of electronic equipment testing, in particular to a backplane testing method. Background technique [0002] In electronic technology, the base circuit board used to connect multiple circuit boards to realize system functions is called a backplane, which is a printed circuit board that provides integration and conversion functions, and is quite specialized in the printed circuit board manufacturing industry. The product. Different from general core function circuit boards, the backplane usually does not need to have powerful computing and processing functions, but it is required to carry different functional modules, so the circuit network and connecting devices on the backplane are dense, and its electromagnetic compatibility performance There are special requirements. Due to the dense and complicated circuits on the backplane, in order to ensure the quality of the product and reduce the failure rate of the product,...
