Description

Technical Field

[0001] The utility model relates to the technical field of protective paper, and particularly relates to a protective paper for an FPC. Background Technique

[0002] FPC, namely flexible printed circuit board, also known as flexible circuit board or flexible printed circuit, is favored for its excellent characteristics such as light weight, thin thickness, and free bending and folding... It is a printed circuit with high reliability and excellent flexibility made of polyester film or polyimide. By embedding circuit design on a bendable and thin plastic sheet, a large number of precision components can be stacked and embedded in a narrow and limited space, thus forming a bendable flexible circuit.

[0003] In order to trace the uniqueness of product information of modules, it is required that each incoming part has a label paper for marking to facilitate product traceability; for COG products, the label paper is generally attached to the FPC. Due to the limitation of the component position, the label paper is generally attached close to the electronic component. For the protection of the component, a sticky protective paper is added on it, and the label paper is also covered synchronously (as shown in the structure diagram of the prior art protective paper, with an insulating PET covering the FPC, covering the component while covering the label paper). Although this method can protect the electronic components of the FPC, when the protective paper is torn off later, due to the stickiness of the protective paper, the words on the previously covered label paper will be lifted, resulting in incomplete or damaged information on the label paper, and thus the information of the product cannot be traced later, affecting the development of the enterprise. Figure 3 As shown in the structure diagram of the prior art protective paper, with an insulating PET covering the FPC, covering the component while covering the label paper. Although this method can protect the electronic components of the FPC, when the protective paper is torn off later, due to the stickiness of the protective paper, the words on the previously covered label paper will be lifted, resulting in incomplete or damaged information on the label paper, and thus the information of the product cannot be traced later, affecting the development of the enterprise.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1-2 , a protection paper for FPC, comprising a protection paper body 1, an insulating PET sheet 3 and a label protection paper 5. The back surface of the protection paper body 1 is an adhesive surface, and the front surface is a non-adhesive surface. The adhesive surface of the protection paper body 1 can be pasted on the FPC, and the non-adhesive surface can be exposed to the outside; the insulating PET sheet 3 is arranged on the back surface of the protection paper body 1. A strip-shaped connecting paper 4 is integrally formed at the bottom of the label protection paper 5. Both the label protection paper 5 and the strip-shaped connecting paper 4 are arranged on the back surface of the protection paper body 1. When the protection paper body 1 is pasted on the FPC, the insulating PET sheet 3 covers the electronic component area of the FPC, and the label protection paper 5 covers the label paper attached beside the electronic component area.

[0025] Please refer to Figure 1-2 , in this embodiment, one surface of the insulating PET sheet 3 is an adhesive surface and the other surface is a non-adhesive surface. The adhesive surface of the insulating PET sheet 3 is pasted on the protection paper body 1 and is close to the middle position.

[0026] Specifically, the adhesive surface of the insulating PET sheet 3 can be directly pasted with the adhesive surface of the protection paper body 1 to improve the firmness after pasting, and the non-adhesive surface can cover the electronic component area of the FPC to avoid bonding with the electronic components and at the same time play a protective effect on the electronic components.

[0027] Please refer to Figure 1-2, in this embodiment, one side of the label protection paper 5 and the strip-shaped connection paper 4 is an adhesive surface, and the other side is a non-adhesive surface. The adhesive surface of the strip-shaped connection paper 4 is covered and pasted on the top of the insulating PET sheet 3, and the adhesive surface of the label protection paper 5 is pasted on the protection paper body 1. The label protection paper 5 is an opaque adhesive paper with a thickness of 0.05 mm, and the thickness of the insulating PET sheet 3 is between 0.08 mm and 0.1 mm.

[0028] Specifically, the adhesive surface of the label protection paper 5 can be directly pasted with the adhesive surface of the protection paper body 1 to improve the firmness after pasting. Since the non-adhesive surface of the label protection paper 5 has no adhesiveness, it can be directly in contact with the label paper to avoid damage to the information on the label paper. The strip-shaped connection paper 4 plays the role of connecting the label protection paper 5 to the insulating PET sheet 3, improving the position stability of the label protection paper 5.

[0029] Please refer to Figure 1 , in this embodiment, a notch one 2 is provided on one side of the top of the protection paper body 1, and the notch one 2 is far from the label protection paper 5; a notch two 6 is provided on one side of the top of the insulating PET sheet 3, and the position of the notch two 6 is close to the notch one 2.

[0030] Specifically, through the designed notch one 2, it is convenient for adjacent electronic components to be placed when pasting the protection paper body 1, and the notch two 6 is designed according to the shape of the FPC, achieving the effect of reducing consumables.

[0031] Please refer to Figure 1 , in this embodiment, the length of the label protection paper 5 is equal to the total length of the insulating PET sheet 3 minus the length of the notch two 6, and the top edge of the label protection paper 5 is flush with the top of the insulating PET sheet 3.

[0032] Specifically, the shape and size of the label protection paper 5 are designed according to the size of the label paper to avoid waste of consumables. At the same time, the top edge of the label protection paper 5 is flush with the top of the insulating PET sheet 3, which can effectively improve the regularity during pasting and avoid misalignment.

[0033] Please refer to Figure 1 , in this embodiment, the area of the protection paper body 1 is larger than the areas of the insulating PET sheet 3 and the label protection paper 5.

[0034] Specifically, after the protection paper body 1 is pasted on the FPC, the insulating PET sheet 3 and the label protection paper 5 on it can be used to shield and protect the corresponding positions.

[0035] During use: paste the adhesive surface of the insulating PET sheet 3 on the protection paper body 1 at a position close to the middle, paste the adhesive surface of the strip-shaped connection paper 4 on the top of the insulating PET sheet 3, and paste the adhesive surface of the label protection paper 5 on the protection paper body 1. Thus, the preparation work of the protection paper for the FPC is completed;

[0036] Then, paste the protection paper body 1 on the PFC as shown in Figure 4 such that the insulating PET sheet 3 covers the FPC electronic component area and the label protection paper 5 covers the label paper. When the protection paper body 1 needs to be torn off later, since the label protection paper 5 is not adhered to the label paper, the integrity of the information on the label paper can be ensured.

[0037] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
