Abstract
The utility model relates to a flexible circuit board which comprises a soft circuit board substrate. The flexible circuit board is characterized in that the bottom face of the soft circuit board substrate is provided with a layer of lower welded bottom disk, the upper surface of the soft circuit board substrate is provided with a first metal layer used for forming a circuit diagram, the first metal layer is provided with an electromagnetic wave shielding layer, and a PET protection layer is arranged under the lower welded bottom disk. By employing the above technical scheme, firstly the bending arrangement is realized through the soft circuit board substrate, then the first metal layer is connected with the electromagnetic wave shielding layer through the insulated material, the shielding effect to an electromagnetic wave is realized, and if the circuit board is needed to be welded to a structure, the PET protection layer is separated.
Description
Technical field
The utility model belongs to wiring board, is specifically related to a kind of flexible circuit board.
Background technology
Wiring board, due to the particularity of use occasion, need to be used Flexible Printed Circuit, and Flexible Printed Circuit maximum is characterised in that and can crookedly places, but some long crooked Hua， Flexible Printed Circuit basic units arranging are because thickness is excessive, there will be the situation of fracture.
Summary of the invention
The utility model, in order to solve the technical problem of mentioning in background technology, provides a kind of flexible circuit board.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of flexible circuit board; comprise Flexible Printed Circuit basic unit; it is characterized in that: described Flexible Printed Circuit basic unit bottom surface is provided with under one deck welds chassis; the upper surface of described Flexible Printed Circuit basic unit is provided with the first metal layer that one deck is used to form line map; described the first metal layer is provided with one deck electromagnetic wave shielding rete, and the below on described lower weldering chassis is provided with one deck PET protective layer.
Between described electromagnetic wave shielding rete and the first metal layer, be provided with space, described electromagnetic wave shielding rete is connected by insulating material in a side with the first metal layer.
Adopt after above technical scheme: first by Flexible Printed Circuit basic unit, realize its crooked setting; then on the first metal layer, by insulating material, connect one deck electromagnetic wave shielding rete; realization is to shielding electromagnetic waves effect; if in the time of wiring board need to being welded in certain structure, tear PET protective layer.
Accompanying drawing explanation
Fig. 1 is structure cutaway view of the present utility model.
