Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0040] At present, after the PCB design is completed, the surface mount connector on the PCB needs to be inspected, and the surface mount connector can only be inspected manually, which is cumbersome and prone to missed inspections, and the inspection efficiency is low . In view of this, this application proposes a surface-mount connector inspection tool, which can automatically inspect the surface-mount connector in PCB design. time, while ensuring that the system has good signal ...

Abstract

The invention discloses a surface-mounted connector pin inspection tool and method, equipment and a medium. The tool comprises a pin inspection module used for obtaining lamination information of a target PCB and pin information of a surface-mounted connector to be inspected on the target PCB, and inspecting pins of the surface-mounted connector to be inspected according to the lamination information and the pin information, a result display module used for visually displaying a result obtained by inspection of the pin inspection module, and a report generation module used for generating an inspection report according to the result obtained by inspection of the pin inspection module and storing the inspection report. In this way, the surface-mounted connector to be inspected can be inspected according to the lamination information and the pin information. Therefore, the surface-mounted connector in PCB design is automatically inspected, the inspection operation is simple and convenient, missing inspection is not easy to occur, the inspection efficiency is improved, the time consumed by the PCB design is saved, and meanwhile, a system is ensured to have good signal integrity.

Description

technical field [0001] The present application relates to the technical field of PCB, in particular to a tool, method, device and medium for checking pins of surface mount connectors. Background technique [0002] As the differential signal rate on the PCB (Printed Circuit Board) is getting higher and higher, in order to ensure that the differential signal has good signal integrity, each part of the interconnection in the high-speed signal link must be designed for impedance optimization, for example, The signal pin and ground pin of the surface mount connector. Regarding the design of signal pins and ground pins of surface mount connectors, SI (Signal Integrity, signal integrity) simulation engineers conduct simulations based on PCB stackup and PCB materials, and give the hollowed out dimensions (W, L) of signal pins, Hollow depth (Void Depth, that is, the distance from the signal pin to the reference layer), the length of the trace (d_heal, d_toe) that connects the ground...
