Problems solved by technology

To be specific, to realize the conduction of double-sided or multi-layer lines in actual implementation, chemical processes such as sinking copper and black holes are generally used. The process is relatively long and the production time is relatively long. For flexible As far as circuit boards are concerned, chemical plating is now used to achieve the conduction of the upper and lower ground wires. This conduction method not only consumes energy, but also costs relatively high

Embodiment Construction

[0019] like Figures 1 to 5 As shown, a double-layer flexible circuit board includes a circuit board base layer 10, a copper foil layer 20 and a shielding layer 30, wherein the circuit board base layer 10 is made of polyimide or polyester film material during specific implementation made.

[0020] The circuit board base layer 10 has a top surface and a bottom surface, and the copper foil layer 20 is disposed on the top surface and the bottom surface of the circuit board base layer 10 at the same time.

[0021] In actual implementation, the copper foil layer 20 first needs to be processed by etching and other processes to obtain a specific required circuit, and then the copper foil layer 20 is placed on the top surface and the bottom surface of the circuit board base layer 10 at the same time.

[0022] The copper foil layer 20 includes a circuit part 21 and a circuit board ground metal part 22 , and the circuit part 21 communicates with the circuit board ground metal part 22 ....

Abstract

The invention relates to a double-layer flexible circuit board, which comprises a circuit board substrate, copper foil layers and a shielding layer. The circuit board substrate is provided with a top surface and a bottom surface. The copper foil layers are simultaneously arranged on the top surface and bottom surface of the circuit board substrate, and comprise a circuit part and a circuit board grounding metal part respectively. A communicating drilled hole is reserved on the circuit board substrate and positioned in the circuit board grounding metal part on the circuit board substrate, and runs through the circuit board substrate and the copper foil layers. A through hole is reserved on the shielding layer and communicated with the communicating drilled hole. A metal switching-on part is arranged in the through hole and the communicating drilled hole from top down, and is communicated with the copper file layer and the shielding layer to electrically connect the copper foil layers arranged on the top surface and bottom surface of the circuit board substrate by the through hole, the communicating drilled hole and the shielding layer.

Description

technical field [0001] The invention relates to a flexible circuit board, in particular to a flexible circuit board in which double-sided circuits of the flexible circuit board can be conducted by means of a physical pressing method and the structure of a shielding layer of the circuit board. Background technique [0002] As we all know, with the progress of society, more and more electronic products are more and more commonly used by people. Among all kinds of electronic products, flexible circuit boards have become an indispensable part of circuit layout. Flexible circuit boards (FPC), also known as "soft board", is a printed circuit made of flexible insulating substrates, which has many advantages that rigid printed circuit boards do not have. For example, it can be freely bent, wound, and folded, and can be arranged arbitrarily according to the requirements of the spatial layout, and can be moved and stretched arbitrarily in three-dimensional space, so as to achieve the ...
