Background
With the advent of the 6G age, the new energy automobile industry has been rapidly developed, the use requirements of high-tech fields such as the chip semiconductor industry, the communication industry and the like on printed circuit boards are higher and higher, the minimum diameter of a drill bit reaches 0.075mm, the production requirements of the PCB circuit boards are not met by a conventional drilling cover plate, and a coated aluminum sheet is mainly used for processing and manufacturing the Printed Circuit Boards (PCBs) and is widely used in electronic products such as televisions, radios, computers and mobile communication. The drilling process of the PCB needs to be carried out under the condition of high rotating speed, and in order to ensure the accuracy of the drilling hole position and improve the drilling quality of the hole wall, a film-coated aluminum sheet is mostly used in the drilling process, wherein the film-coated aluminum sheet is more common.
The single-sided coated aluminum plate commonly used at present has a plurality of limitations in the drilling process due to materials and structures, including the problem 1: the single-sided film-coated aluminum plate has more severe requirements on temperature and humidity storage environment and higher storage cost;
problem 2: the main material of the single-sided film-coated aluminum plate is water-soluble glue with poor temperature resistance, and heat generated in the drilling process can melt the water-soluble film and adhere to the chip grooves of the drill bit;
problem 3: the single-sided film-coated aluminum plate film body is water-based carrier production process, water treatment can cause 2 times of pollution, and is not environment-friendly;
problem 4: the surface film body is removed by water to pollute the water when the water-soluble aluminum sheet waste is recovered and difficult to treat.
Disclosure of Invention
The utility model aims to provide a single-sided film-coated aluminum plate, which solves the problems in the prior art.

In the figure: 1. a buffer lubrication layer; 2. a corona treatment layer; 3. an aluminum foil substrate layer.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1, the present utility model provides a technical solution: the single-sided coated aluminum plate is characterized in that a buffer lubrication layer 1 is bonded with an aluminum foil substrate layer 3 through a corona treatment layer 2, the buffer lubrication layer 1 is made of a high polymer resin material (LDPE, PP, PE, PET, polyethylene, polypropylene and polyethylene wax), oil stains on the surface of an aluminum foil are cleaned by adding the corona treatment layer 2 through physical super-roughening plasma treatment, and the oil stains are cooled by rolling the buffer lubrication layer 1 and the aluminum foil substrate layer 1 through equipment glue rollers to form a water-insoluble coated aluminum sheet.
The buffer lubrication layer 1 is made of high polymer resin materials (LDPE, PP, PE, PET, polyethylene, polypropylene and polyethylene wax), and the buffer lubrication layer 1 is a high polymer film made of resin particles with hot melting performance and self-lubricating effect, so that the drill bit can be instantly deformed and stabilized on the contact plate surface of the drill bit, the deflection of the drill bit is reduced, meanwhile, the heat of the drill bit is absorbed to keep the rigidity of the drill bit, the film property of the buffer lubrication layer 1 after absorbing the heat of the drill bit is decomposed into water and carbon dioxide at high temperature, and therefore, the water and carbon dioxide are converted into dust after being cut by the drill bit and are absorbed so as not to be wound on the drill bit, and therefore, the problem that waste residue generated in the drilling process remains in the PCB hole at the later stage, so that the PCB is extremely easy to process after drilling, the problems of hole blockage, wire winding, hole wall pollution, high breakage rate and the like are avoided.
The aluminum foil substrate layer 3 is made of metal aluminum foil, the thickness of 1 or 8 series pure aluminum foil is 0.02-0.3 mm, the surface of the aluminum foil substrate layer 3 is used for being attached to the surface of the PCB, and the rigid substrate body is attached to the surface of the PCB, so that the probability of orifice burrs can be reduced.
