Embodiment Construction

[0013] S1. backplane (hereinafter referred to as: BP) is the backplane, which is provided by the designated supplier, and related connectors and other components are purchased according to the process.

[0014] S2. Divide the working area into three blocks: plug-in area, crimping area, and testing area. Components are different from soldered parts such as PCB, but solder-free connectors, which ensure the perfect contact between the PIN pins of all connectors and the pad holes on the BP, and ensure that the pins are not bent, reversed, or misplaced. Use special tooling to detect the above problems on the BP that has completed the plug-in. After confirming that it is correct, place it on the marked special anti-static logistics vehicle and wait for the test.

[0015] S3: Before the test, two basic tasks need to be prepared: one is the design and production of the test framework and test modules. According to the size of the backplane and the wiring direction, make a test frame...

Abstract

The invention discloses a backboard detection method. Firstly, the flatness and the damage of the surface of a backboard are detected, if the surface of the backboard is damaged, subsequent detection is directly given up, and if the surface of the backboard is qualified, subsequent circuit performance detection is carried out. The detection item is complete, and the detection efficiency is high.

Description

technical field [0001] The invention belongs to the field of backboard detection methods. Background technique [0002] Applications in the field of backplane technology involve communications, aerospace, automobiles, base stations and other fields. As the optical network changes from 2G-3G-4G-5G, the technical requirements of the backplane are also constantly changing, especially the number of layers, layout, and pressure resistance of the backplane; the crimping requirements of connectors and high-density connectors The introduction of new ones has also made higher precision requirements for testing requirements. [0003] At present, the backplane test is usually to check whether the basic circuit of the backplane is normal, and there is no complete method for testing each parameter of the backplane and whether it can operate normally. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention provides a backplane detection me...
