Problems solved by technology

[0004] However, limited by the size of the connectors at both ends of the traditional flexible printed circuit, the connectors at both ends of the flexible printed circuit cannot provide more grounding pins so that the upper board electrically connected by the flexible printed circuit Good grounding contact with lower plate
That is, the flexible printed circuit and the connector sockets electrically connected to the connectors at both ends of the flexible printed circuit cannot provide a large area of ​​ground contact, so that the electronic components mounted on the upper board and the lower board and Electrostatic discharges generated in circuits are quickly and completely grounded

Abstract

The invention provides a flexible printed circuit module comprising a main body and at least one connecting socket, wherein the main body comprises a first connecting end, a band body part and a second connecting end. The first connecting end and the second connecting end are respectively arranged at two ends of the band body part and respectively provided with a connector. The band body part is internally provided with a plurality of layers of circuits comprising grounding circuits in advance; the first connector and the second connector are electrically connected through the circuits arranged inside the band body part; and the connecting socket is electrically connected to at least one of the connectors of the main body. A conductive coating layer is coated on the periphery of the connecting socket and electrically connected with the grounding circuits.

Description

technical field [0001] The invention relates to a flexible printed circuit module, in particular to a flexible printed circuit module which can increase the grounding contact mode and enhance electrostatic discharge protection. Background technique [0002] Flexible printed circuit (flexible printed circuit, FPC) is widely used in mobile phones and personal digital assistants (PDA) due to its light weight, thin thickness, easy three-dimensional assembly after folding, and ability to withstand multiple dynamic deflections. and other electronic devices. [0003] As the volume of electronic devices gradually shrinks, the space for installing electronic components in them becomes more and more limited, while the functions of electronic devices become more and more, so that the electronic devices installed in electronic devices Components are becoming more and more integrated. When the electronic device is in operation, various electronic components and circuits installed there...
