Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to an automatic testing device for a multi-layer high-order HDI high-density PCB circuit board. Background Art

[0002] Multilayer, high-order, high-density HDI PCBs are manufactured using high-density interconnect technology. Building on traditional multilayer PCBs, they achieve a higher level of circuit integration by adding denser vias and finer traces. This allows for more circuit connections within a limited space, improving the board's integration. Advanced microfabrication techniques enable smaller apertures and trace widths, reducing board size. The multilayer design reduces interference and loss during signal transmission, improving signal stability and reliability.

[0003] Existing technologies, such as an invention patent for a fully automatic testing device for PCB circuit boards, with authorization announcement number CN117471293B, enable direct online testing of PCB boards with tray assemblies, improve equipment production capacity, reduce the risk of damage during product transfer, and reduce equipment footprint.

[0004] At present, there is still a lack of a device that can facilitate the stable clamping of multi-layer high-order HDI high-density PCB circuit boards, and then use circular transportation to save space and facilitate detection. Utility Model Content
