Abstract

The invention provides a flexible printed circuit, which comprises a main body and at least one ground layer, wherein the main body comprises a first connection terminal, a belt body part and a second connection terminal; the first connection terminal and the second connection terminal are positioned at both ends of the belt body part respectively; the first connection terminal and the second connection terminal are provided with a first connector and a second connector respectively; the belt body part is internally prese with a plurality of layers of circuits which comprise ground circuits; the first connector is electrically connected with the second connector through the circuits arranged inside the belt body part; the belt body part is provided with a plurality of via openings in a run-through way, and the ground layer is arranged on at least one surface of the main body; and the ground layer is electrically connected with the ground circuits inside the belt body part through the via openings. The invention also relates to a method for manufacturing the flexible printed circuit.

Description

technical field [0001] The invention relates to a flexible printed circuit, in particular to a flexible printed circuit capable of increasing ground contact and a manufacturing method thereof. 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 bendings. 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, which inevitably makes the electronic devices installed in electronic devices more and more difficult. Electronic components are becoming more and more integrated. When the electronic device is in operation, various electronic components and circuits in...
