Problems solved by technology
During the shearing process of the adhesive sheet, when the resin in the semi-cured state is sheared and broken, a large amount of resin powder will drop during shearing, and the resin powder will accumulate over time, which will seriously pollute the equipment and high-purification production workshop, and even cause Adverse effects such as skin allergies of employees, and resin powder is easily carried into the next section, which directly affects the finished product pass rate of copper clad laminates and multilayer printed circuit laminates
[0005] In order to reduce the drop of resin powder, researchers have made many improvements to the production process of the adhesive sheet. One of the most important methods is to heat-seal the edge of the cut adhesive sheet immediately to prevent the falling The resin powder is re-melted on the adhesive sheet, but it takes a long time, consumes a lot of energy, and it is easy to cause carbonization of the resin powder due to high temperature, forming black spots and impurities; The bonded sheet is preheated, and the bonded sheet is softened before shearing. This method can eliminate the resin powder from the source, but the speed is slow, which seriously affects the shearing efficiency of the shearing machine, thereby affecting the production efficiency, and the preheating device is easy. Contaminated, not easy to clean

Embodiment Construction
[0026] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments.
[0027] Such as figure 2 As shown, the present invention provides a device 10 for producing adhesive sheets, which includes an uncoiler 200, a glue tank 300, a glue removal device 800, an oven 400, a cooling wheel 500, Shearing device 600, stacking table 700.
[0028] When adopting above device to produce bonding sheet 110, its production method is as follows, comprises the following steps:
[0029] First enter the dipping process, the rolled reinforcing material 100 is first unrolled by the uncoiler 200, the pulling reinforced material 100 is flattened, and then sent into the glue tank 300, so that the reinforcing material 100 is impregnated in the resin glue, And form a glue layer on the surface of the reinforcing material 100;
[0030] Then enter the degumming process, when the degumming device...

The invention relates to the technical field of a copper-clad plate, and specifically to a production method for a bonding sheet. The production method comprises a gum-dipping working procedure and a baking working procedure; and a gum-removing working procedure is further performed between the gum-dipping working procedure and the baking working procedure to form multiple gum liquid dents that are parallel with the latitudinal direction of a reinforced material in a gum liquid layer on the surface of the reinforced material. The phenomenon of resin powder dropping in shearing the bonding sheet is effectively reduced, and high yield of the copper-clad plate in post production is ensured; the manufacturing method is high in production speed, high in production efficiency and high in percent of pass; in addition, the invention also relates to a production apparatus for the bonding sheet, wherein the production apparatus applies the production method for the bonding sheet; and the bonding sheet with a low amount of dropped resin powder in production and high percent of pass can be produced by the production apparatus.
Description
technical field [0001] The invention relates to the technical field of copper clad laminates, in particular to a production method of an adhesive sheet and a production device for realizing the production method. Background technique [0002] Adhesive sheet, also known as prepreg, is an indispensable semi-finished product for the production of copper clad laminates and multilayer printed circuit boards. It is mainly composed of reinforcing materials, such as glass fiber, non-woven fabrics or wood pulp paper, etc. It is formed by soaking and drying. The resin of the prepreg can be re-melted and bonded and completely cured at high temperature. Therefore, different types of prepregs can be laminated. After high-temperature hot pressing by a laminator, a copper-clad laminate or multi-layer printing that meets the requirements can be formed. Line laminate. [0003] The manufacturing process and device of traditional adhesive sheet such as figure 1 As shown, after the reinforcin...
