Description
[ technical field ] A method for producing a semiconductor device
The present invention relates to a flexible flat cable, and more particularly to a flexible flat cable with a metal foil shielding reinforcing plate.
[ background of the invention ]
In order to reinforce the free end of the conventional flexible flat cable, i.e., the end of the flat cable, a length of relatively hard reinforcing member is provided at both ends of the flexible flat cable to increase the hardness of both ends of the flexible flat cable. In practical applications, the flexible flat cable is subjected to a punching or cutting process according to the required length of the cable, so as to cut the longer flexible flat cable into a single section/piece of flexible flat cable; however, when the reinforcing member is cut during the punching or cutting process of the flexible flat cable, if the reinforcing member is made of a conductive material, metal chips or wires may be generated during the cutting process of the reinforcing member, so that the flexible flat cable may be short-circuited.
In view of the above, the present invention provides a flexible flat cable with a metal foil shielding reinforcing plate, which is used to solve the disadvantages caused by the conventional connector.
[ Utility model ] content
The first objective of the present invention is to provide a flexible flat cable with a metal foil shielding reinforcing plate to avoid short circuit of the flexible flat cable.
The second objective of the present invention is to provide a flexible flat cable with a metal foil shielding reinforcement plate, which uses a reinforcement member composed of a metal layer and a non-metal layer with asymmetric lengths to achieve the effects of easily inserting a connector, separating from the connector, increasing the reliability of electrical contact, and avoiding short circuit.
The third purpose of the present invention is to avoid the short circuit of the flexible flat cable by the space formed by the end of the metal layer and the end of the non-metal layer according to the flexible flat cable with the metal foil shielding reinforcing plate.
To achieve the above and other objects, the present invention provides a flexible flat cable having a metal foil shielding reinforcing plate. The flexible flat cable comprises a conductor, an electroplated layer, a first insulating layer, a second insulating layer and a reinforcing member. The conductor has a first surface and a second surface. The plated layer is disposed on the second surface and the plated layer is disposed at a free end of the conductor. The first insulating layer is arranged on the first surface. The second insulating layer is arranged on the second surface. The reinforcing member has a metal layer and a non-metal layer. The reinforcing member is disposed on one side of the first insulating layer and adjacent to the free end of the conductor. The metal layer is stacked on one side of the nonmetal layer and the other side of the nonmetal layer and is arranged on the first insulating layer. Wherein the end of the non-metallic layer adjacent to the free end is closer to the free end than the end of the metallic layer adjacent to the free end.
Compared with the prior art, the flexible flat cable with the metal foil shielding reinforcing plate can solve the problem that short circuit occurs between a plurality of wires in the flexible flat cable due to metal wires or metal scraps generated by punching or cutting processes of the flexible flat cable.
The specific techniques employed in the present invention will be further described with reference to the following examples and accompanying drawings.

[ detailed description ] embodiments
For a fuller understanding of the objects, features and advantages of the present disclosure, reference should be made to the following detailed description taken in conjunction with the accompanying drawings.
In this disclosure, the use of "a" or "an" is used to describe elements, components and assemblies described herein. This is for convenience of illustration only and provides a general sense of the scope of the present disclosure. Thus, unless clearly indicated to the contrary, such description should be read to include one, at least one and the singular also includes the plural.
In this disclosure, the terms "comprising," "including," "having," "containing," or any other similar term are intended to cover non-exclusive inclusions. For example, an element, structure, article, or apparatus that comprises a plurality of elements is not limited to only those elements but may include other elements not expressly listed or inherent to such element, structure, article, or apparatus. In addition, unless expressly stated to the contrary, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or".
Fig. 1 is a side view of a flexible flat cable with a metal foil shielding reinforcing plate according to an embodiment of the present invention. In fig. 1, a flexible flat cable 10 with a metal foil shielding reinforcing plate includes a conductor 12, a plating layer 14, a first insulating layer 16, a second insulating layer 18 and a reinforcing member 20.
The conductor 12 has a first surface 122 and a second surface 124. In fig. 1, the first surface 122 refers to an upper surface of the conductor 12 and the second surface 124 refers to a lower surface of the conductor 12. Further, in fig. 1, the left-side end of the conductor 12 is defined as a free end 126. The material of the conductor 12 may be a metal such as pure copper. The conductor 12 is used for transmitting electrical signals such as data or power, and has an anti-electromagnetic interference effect. And (3) also. Conductor 12 refers to one or more wires, here exemplified by one wire.
The first insulating layer 16 is disposed over the first surface 122. The first insulating layer 16 can isolate electrical signals between the one or more conductors 12 or external electrical signals (e.g., static electricity, etc.) from interfering with each other.
The second insulating layer 18 is disposed below the second surface 124, and has the same characteristics as the first insulating layer 16, and the first insulating layer 16 and the second insulating layer 18 are coated to further ensure that the conductor 12 is not interfered by the electrical characteristics.
The stiffener 20 has a metal layer 202 and a non-metal layer 204. Here, the stiffener 20 is disposed over the first insulating layer 16 and adjacent to the free end 126 of the conductor 12. Also, the metal layer 202 is stacked over the non-metal layer 204 and the non-metal layer 204 is disposed over the first insulating layer 16. The metal layer 202 is a metal foil formed of at least one metal of aluminum, copper, silver, tin, and gold; the material of the non-metal layer 204 may be non-metal such as polyethylene terephthalate (PET).
Here, the end of the non-metal layer 204 adjacent to the free end 126 is closer to the free end 126 than the end of the metal layer 202 adjacent to the free end 126. Due to the arrangement structure of the nonmetal layers 204 and 202, a space SP is formed between the end of the metal layer 202 and the end of the nonmetal layer 204. In the present embodiment, the cross-sectional shape of the space SP is illustrated as a triangle, and in other embodiments, the cross-sectional shape of the space SP may be any shape. Here, the height h of the triangular space SP ranges from 0.01 mm to 0.1 mm, preferably the height h is 0.05 mm, and the width w ranges from 0.1 mm to 0.5 mm, preferably the width w is 0.3 mm.
It is noted that the ends of the metal layer 202 are illustrated as being aligned with the free ends 126 of the conductors 12. In other embodiments, the ends of the metal layer 202 may not be aligned with the free ends 126 of the conductors 12.
The flexible flat cable 10 with the metal foil shielding reinforcing plate may further include an adhesive layer (not shown) disposed on the first surface 122 for bonding the reinforcing member 20 and the first insulating layer 16.
Although the embodiments of the present disclosure have been described above, it should be understood that various changes in the form, construction, features, methods and quantities described in the claims may be made by those skilled in the art without departing from the spirit and scope of the present disclosure, and therefore the scope of the present disclosure should not be limited by the claims appended hereto.
