Description

Technical Field

[0001] The utility model relates to the technical field of copper clad plate lamination, in particular to a laminated structure of a copper clad plate. Background Art

[0002] Copper-clad laminates, also known as base materials, are a type of sheet material made by impregnating a reinforcing material with resin, coating one or both sides with copper foil, and then hot-pressing. With the development of society and advancements in technology, electronic products have become indispensable in people's daily lives and work, and the demand for electronic components is increasing year by year. The use of copper-clad laminates, the primary material for electronic products, has also increased rapidly. According to electronics industry statistics, demand has reached nearly 500 million square meters per year and continues to increase. To meet this enormous demand, manufacturers across the copper-clad laminate industry chain are continuously developing equipment, production processes, and new materials to ensure efficient and environmentally friendly copper-clad laminate production.

[0003] For example, the disclosure of authorization announcement number CN208247684U discloses a copper clad laminate pressing machine, comprising a machine platform, characterized in that: a cavity is provided on the machine platform, two ends of the cavity are provided with a first slide rail, the first slide rail is provided with a plurality of sliders, a heating plate is provided between the two sliders, the front end of the heating plate is provided with a roller groove, the roller groove is provided with a roller, an upper pressing plate is provided above the upper heating plate, a lower pressing plate is provided below the lower heating plate, an oil cylinder is provided below the lower pressing plate, a step is provided at the front end of the cavity, a sealing strip is provided on the step, and two upper and lower slide rails are provided on the machine platform. The utility model can realize the pressing of copper foil, a heat conducting plate and an aluminum substrate into a copper clad laminate, and has a simple structure and a reasonable design.

[0004] However, in the current existing laminated structure, when pressing the copper clad laminate, the bottom is pushed up to generate extrusion pressure to complete the pressing of the copper clad laminate. This force-bearing method only bears force on one side, resulting in uneven force on the copper clad laminate. At the same time, when vacuum is extracted, sealing is an important factor affecting the vacuum. In the production process, poor sealing of the sealing door will lead to pressure relief in the vacuum environment, thereby affecting the production process of the copper clad laminate.
