Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "front", "rear", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; may be mechanically coupled, may be directly coupled, or may be indirectly coupled through an intermediary. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1 to 2, the protective adhesive layer structure applied to the FPC board in this embodiment includes an FPC board body, where the FPC board body is formed by assembling a plurality of PCS units 1, and the PCS units 1 are respectively provided with a protective adhesive layer 2;
the protective adhesive layer 2 comprises a PET film 21 and a pressure-sensitive adhesive layer 22 which are arranged in a laminated manner;
the PET film 21 is provided with a glue-free area 211 and a glue area 212;
one side of the pressure-sensitive adhesive layer 22 is set as a first adhesive surface, the other side of the pressure-sensitive adhesive layer 22 is set as a second adhesive surface, the first adhesive surface is adhered to the PCS unit 1, and the second adhesive surface is not separated from the adhesive area 212.
This embodiment simple structure, reasonable in design, pressure sensitive adhesive layer 22 does not leave the type with gluey district 212 of PET membrane 21 and is connected, an organic whole sets up promptly, compare in reducing whole PET membrane 21 and set up pressure sensitive adhesive layer 22, the cost is lower, simultaneously can be through the setting of no gluey district 211 with there being gluey district 212, pinpoint, it is convenient to paste the dress, after the use, because PET membrane 21 is not from the type setting with pressure sensitive adhesive layer 22, through peeling off PET membrane 21, can tear pressure sensitive adhesive layer 22 off in step, make PCS unit 1 clean and do not occupy the dress space, excellent in application effect.
In particular, the glue area 212 and the non-glue area 211 need to be reserved according to the end product.
Specifically, in some embodiments, the first adhesive surface has a smaller viscosity than the second adhesive surface, in this embodiment, the side with a smaller viscosity, that is, the side with a weaker adhesive property, is connected to the PCS unit 1, so as to facilitate the synchronous tearing of the pressure-sensitive adhesive layer 22 after the mounting is completed, by peeling off the PET film 21, the structure is simple, and the practicability is strong, and in this embodiment, specifically, by using a commercially available strong and weak pressure-sensitive double-sided adhesive, such as a crown DS31-6025 strong and weak double-sided adhesive, only the side with a stronger adhesive property is replaced with the release paper to be the PET film 21 of this application.
Specifically, the PET film 21 is set as a blue PET film 21, and in the embodiment, the blue PET film 21 is specifically adopted, so that the protection effect is good, the color is easy to identify, and the positioning and use during mounting are facilitated.
In some embodiments, the position that PET membrane 21 and the second is glued the face and is connected sets up to no silicone oil face, because the setting of silicone oil face can reduce the adhesive force, and then reduces the viscous force, in this embodiment, through with PET membrane 21 with the position that the second is glued the face and is connected sets up to no silicone oil face, can ensure that the viscous force is stronger, realizes not leaving the type and connects, and then is convenient for subsequent synchronous peeling off.
In some embodiments, the adhesive area 212 is located in the non-adhesive area 211, and the arrangement of this embodiment can ensure that the non-adhesive area 211 can also be arranged in a manner of being attached to the PCS unit 1 by the connection between the adhesive area 212 and the pressure-sensitive adhesive layer 22, so as to achieve a better protection effect.
In some embodiments, the adhesion force between the first adhesive surface and the PCS unit 1 is set to be 115-125g/inch, and in this embodiment, by setting the adhesion force between the first adhesive surface and the PCS unit 1 to be about 120g/inch, the adhesion is ensured, and at the same time, the subsequent tearing-off is facilitated, and no residual adhesive is left after the tearing-off, so that the PCS unit is cleaner.
The above-mentioned embodiments only represent several embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention.
