Abstract

The utility model provides a novel glue-resisting film, the buffer layer in the middle of including and be located the protective layer at both ends about the buffer layer, the inside center department bonding of buffer layer is fixed with the glass fiber rete, and the protective layer is one of modified PET, PA, PP material, and buffer layer and protective layer adopt crowded mode altogether to be fixed together, will go up the middle and lower three-layer and together extrude the combination, form the trinity glue-resisting film of integration, the thickness of protective layer is 20-30 microns, the thickness of buffer layer is 150-250 microns, the thickness of glass fiber rete is 10-20 microns. The utility model provides a novel hinder glued membrane adds the glass fiber rete in the inside of buffer layer and increases its mechanical strength and horizontal tensile strength ability to reduce the mobility of buffer layer in order to improve the production yield.

Description

Novel glue-blocking film

Technical Field

The utility model relates to a printed circuit board hinders glued membrane technical field, and is very special a novel hinder glued membrane.

Background

With the development of science and technology, circuit boards are continuously developed towards high precision, high density and high reliability, and the size, the cost and the performance are continuously reduced and improved. In the actual production process of printed circuit board manufacturing, in order to tightly combine the inner core board and the prepreg, the inner core board and the prepreg are often pressed under the conditions of high temperature and high pressure, but the traditional glue-blocking film has high fluidity of the intermediate layer, so that the production efficiency is low, and the number of scrapped products is large.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel hinder glued membrane in order to solve above-mentioned problem.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a novel glue blocking film, includes middle buffer layer and the protective layer that is located both ends about the buffer layer, the inside center department bonding of buffer layer is fixed with the glass fiber rete, and the protective layer is one of modified PET, PA, PP material, and buffer layer and protective layer adopt crowded mode altogether to be fixed together, will go up the three-layer and together extrude the combination down, form the trinity glue blocking film of integration.

Preferably, the thickness of the protective layer is 20 to 30 micrometers.

Preferably, the buffer layer has a thickness of 150 to 250 micrometers.

Preferably, the thickness of the glass fiber film layer is 10-20 microns.

The utility model provides a novel glue-blocking film. The method has the following beneficial effects:

the utility model provides a novel hinder glued membrane adds the glass fiber rete in the inside of buffer layer and increases its mechanical strength and horizontal tensile strength ability to reduce the mobility of buffer layer in order to improve the production yield.

Drawings

Fig. 1 is a schematic view of the structure of the novel glue-blocking film of the present invention.

In the figure: 1. a buffer layer; 2. a protective layer; 3. a glass fiber film layer.

Detailed Description

The invention is further described with reference to the following drawings and detailed description:

in the description of the present invention, it should be noted that the terms "top", "bottom", "one side", "the other side", "front", "back", "middle part", "inside", "top", "bottom", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of description and simplification of the description, but does 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; the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance; furthermore, unless expressly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, as they may be fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. 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 figure 1, a novel glue-blocking film, buffer layer 1 in the middle of including and the protective layer 2 that is located buffer layer 1 upper and lower both ends, the inside center department adhesion of buffer layer 1 is fixed with glass fiber rete 3, and protective layer 2 is one of modified PET, PA, PP material, and buffer layer 1 and protective layer 2 adopt crowded mode altogether together fixed, will go up the combination of together extruding of middle and lower three-layer, form the trinity glue-blocking film of integration, the thickness of protective layer 2 is 20-30 microns, the thickness of buffer layer 1 is 150-250 microns, the thickness of glass fiber rete 3 is 10-20 microns, the utility model discloses well buffer layer 1 and protective layer 2 combine the high temperature planarization good, and glass fiber rete 3 has reduced the mobility of buffer layer 1.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
