Embodiment Construction

[0018] The specific implementation and principle of the present invention will be described in detail below with reference to the corresponding drawings.

[0019] Referring to FIG. 1, FIG. 1 shows a system 100 for testing a backplane according to the present invention. In this embodiment, the system 100 includes a test implementation unit 40 , a control unit 20 and an interface board 30 . The interface board 30 includes a gating module 31 and a measuring module 32 . There are also connectors on the interface board 30 , which correspond to the connectors on the backboard, and the backplane and the interface board 30 are connected to each other through the connectors on the interface board 30 .

[0020] The test implementation unit 40 is used to run the test software platform and the test program. The test implementation unit 40 may be a general-purpose personal computer. The test software platform provides a common development and test environment. The test program runs on ...

Abstract

A test system of back plate is prepared as using test realization unit to operate test program, connecting interface plate to said back plate, setting control unit between said test realization unit and said interface plate and using said control unit to control interface plate to carry out test operation on said back plate.

Description

technical field [0001] The invention relates to the field of test systems, in particular to a backplane test system. Background technique [0002] Generally, a circuit board used to connect multiple circuit boards to realize system functions is called a backplane, and the backplane has always been a specialized product in the printed circuit board (PCB, Printed Circuit Board) manufacturing industry. Its design parameters are very different from most other circuit boards. Some stringent requirements need to be met in production, and the noise margin and signal integrity also require the backplane design to follow unique design rules. [0003] Backplanes are tested for a variety of reasons, the most important being to improve the quality of the finished backplane during production. Since some degree of error may occur in all production processes, these errors will lead to a decline in the production qualification rate. By testing the backplane, the failure and maintenance co...
