Description
Technical Field
The invention belongs to the technical field of copper-clad plate preparation, and particularly relates to a copper-clad plate gluing and drying device.
Background
The copper-clad plate is an extremely important basic material of the printed circuit board, and various printed circuit boards with different forms and different functions are manufactured into different printed circuits (single-sided, double-sided and multilayer) by selectively carrying out the working procedures of processing, etching, drilling, copper plating and the like on the copper-clad plate. The copper-clad plate is used as a substrate material in the manufacture of the printed circuit board, mainly plays roles of interconnection conduction, insulation and support for the printed circuit board, and has great influence on the transmission speed, energy loss, characteristic impedance and the like of signals in a circuit, so that the performance, the quality, the processability in the manufacture, the manufacture level, the manufacture cost, the long-term reliability and the stability of the printed circuit board are greatly dependent on the copper-clad plate. The copper-clad plate is an indispensable important electronic material for all electronic complete machines, including all electronic products such as aviation, aerospace, remote sensing, remote measuring, remote control, communication, computers, industrial control, household appliances and even advanced toys for children. With the increasing level of technology, some special electronic copper clad laminates have been used to directly manufacture printed electronic components in recent years.
Due to the miniaturization, light weight and thinness of electronic products, the printed circuit board is forced to have various high-quality and high-technical characteristics, so that the manufacturing technology of the printed circuit board directly relates to various high and new technologies in the present day, and the copper-clad plate, which is the main and most important material, must have various high-quality and high-technical characteristics along with the manufacturing technology of the printed circuit board. Therefore, the status of copper-clad plate in electronic information industry is more and more important.
The structure of the copper-clad plate comprises: the insulating laminated board composed of the substrate, the high polymer synthetic resin and the reinforcing material can be used as the substrate of the copper-clad plate; the copper foil is a key material for manufacturing the copper-clad plate and has high conductivity and good weldability; the copper-clad plate adhesive is an important factor for firmly covering the copper foil on the substrate, and the peel strength of the copper-clad plate mainly depends on the performance of the adhesive.
In the preparation process of the copper-clad plate, the gluing and drying of the substrate are the most important processes, and the traditional method comprises the following steps: pumping the mixed glue solution into a glue tank by a pump, continuously immersing the glass fiber cloth into the glue tank by a gluing machine to enable the glue solution to be adhered to the glass fiber cloth, and drying the glued glass fiber cloth in an oven of the gluing machine at high temperature to form a bonding sheet. Because the single piece is directly dried in an oven at 200-300 ℃ after the glue is applied and the surface is dried, the baking time is 20 minutes to 1 hour, the method has the defects that: 1) the glue is cut, stacked into a required thickness and pressed, so that the foaming is easy to occur, the reject ratio is high, the gluing speed is low, the speed is only about 10 minutes and 5-10 meters, and the gluing efficiency is low; 2) the height of a gluing machine is limited (6-9 m high), and the height of a factory building is difficult to match; 3) the precision requirement on the laminating machine is high, and the equipment investment is large; 4) the production of workers is complex, the process is difficult to master, and defective products are easy to produce; 5) the electrical properties are not stable enough; 6) the pressing time is long, and the electricity cost is 30-50% more; 7) in Guangdong areas, typhoons are more, and factory buildings need to be made into dust-free workshops for a long time; typhoon is afraid, and the finding of a factory building is difficult; once the plant is damaged by typhoon, the plant is shut down (the maintenance equipment consumes electricity and time, and the production is influenced).
