Problems solved by technology

However, when the operating frequency of the communication standards (such as USB, SATA, HDMI, PCIE, and DP (DisplayPort), etc.) applied in the electronic device is higher, the impedance mismatch (impedance mismatch) occurring on the flexible board connector will be obvious. impact on the performance of electronic devices
Excessive impedance mismatch will cause shutdown of electronic devices or deterioration of compatibility

Embodiment Construction

[0044] Please refer to figure 1 , in this embodiment, the electronic assembly 10 can be applied inside an electronic device, such as a docking station for a notebook computer or a tablet computer. The electronic assembly 10 includes two circuit boards 12 (PCB), two circuit board connectors 14 (FPC connector) and one circuit board 16 (FPC). The flexible board connectors 14 are installed on the circuit hard boards 12 respectively. The circuit flexible board 16 has two contact portions 16 a, and the two contact portions 16 a are respectively connected to the flexible board connectors 14 . Therefore, these flexible board connectors 14 and circuit flexible boards 16 can be electrically connected to each other, and then these circuit rigid boards 16 can be electrically connected to each other. Therefore, the soft circuit board 16 (such as the path and cross-sectional area of ​​the wires, etc.) can be customized according to the positions of the hard circuit boards 12, thereby incr...

Abstract

The invention discloses a pin arrangement and an electronic assembly. The pin arrangement is used for a soft board connector, and includes a pin column comprising a pair of grounding pins, a pair of differential pins positioned between the pair of grounding pins and an un-connected pin positioned between the pair of differential pins. Or, the un-connected pin is disposed between one of the grounding pins and adjacent one of the differential pins. The distance between the differential pins, and / or the distance between one of the differential pins and nonadjacent one of the grounding pins is increased by adding the un-connected pin between the pair of differential pins and / or between one of the differential pins and adjacent one of the grounding pins, so that the differential characteristic impedances of the differential pins are increased and impact of impedance mismatch is reduced.

Description

technical field [0001] The invention relates to an electronic device, and in particular to a pin arrangement applied to a flexible board connector and a corresponding electronic assembly. Background technique [0002] Since Flexible Printed Circuits (FPCs) have the benefits of flexibility and space saving, FPCs are often used in foldable electronic devices, such as docking stations for notebook computers and tablet computers. The wire (trace) of the circuit flexible board can adjust its width and thickness to adjust the impedance during design and manufacture, so impedance control (impedance control) can be performed on the circuit flexible board. Since the circuit soft board is a common interconnection, the FPC connector (FPC connector) used to clamp the circuit soft board must also be designed to be universal, so impedance control will not be performed on the flexible board connector. . [0003] In some applications, such as USB3.0 signal transmission in electronic devic...
