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...
