Description

Technical Field

[0001] The utility model relates to the technical field of PCB drilling, in particular to a PCB drilling lubricating pad. Background Art

[0002] With the development of technology and the popularization of artificial AI intelligence, high-precision circuit design requires high thermal conductivity, heat dissipation, high frequency, high speed and high copper thickness materials, and the requirements for PCB drilling quality are getting higher and higher.

[0003] During the drilling process of traditional PCB drilling pads, the base plate burr is too large, the hole roughness exceeds the standard, and the ICD (hole wall separation) is abnormal, resulting in quality risks and product scrapping, which increases production costs. Utility Model Content

[0004] The utility model aims to provide a PCB drilling lubrication pad to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a PCB drilling lubrication pad, comprising a wood fiberboard, the top and bottom of the wood fiberboard are both bonded with a composite fiber reinforcement layer, the side of the composite fiber reinforcement layer away from the wood fiberboard is bonded with a thermal resistance material layer, the side of the thermal resistance material layer away from the composite fiber reinforcement layer is bonded with a heat conductive sheet layer, the side of the heat conductive sheet layer away from the heat resistance material layer is bonded with a dipped lubricating paper layer, and nano-scale lubricating particles are evenly distributed in the dipped lubricating paper layer.

[0006] The thickness of the wood fiberboard ranges from 1.5 to 3 mm.

[0007] The composite fiber reinforcement layer has a thickness ranging from 0.1 to 0.5 mm.

[0008] The thickness of the heat conducting sheet layer is 0.05-0.2 mm.

[0009] The thickness of the thermal resistance material layer is in the range of 0.2-0.8 mm.

[0010] The dipped lubricating paper layer slip coating is prepared by mixing three or more of polyethylene glycol polymer, polyvinyl alcohol and polyacrylic acid, and has a thickness of 0.1-0.3 mm.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The wood fiberboard of the utility model provides a solid structural support for the pad, ensuring that it can remain stable during use and is not easily deformed or damaged. The composite fiber reinforcement layer is composed of carbon fiber or glass fiber, which significantly enhances the overall structural strength and durability of the pad. This can effectively prevent the pad from tearing or deforming during the drilling process and improve the service life. The impregnated lubricating paper layer is prepared with a polymer resin coating and has an excellent lubricating effect. This layer can not only absorb the heat of the drill bit, but also maintain the rigidity of the drill bit and greatly reduce friction, thereby improving the efficiency and quality of drilling. The addition of nano-scale lubricating particles further enhances the lubrication effect, helps to reduce the wear and heat generation of the drill bit, and has a significant positive effect on extending the service life of the drill bit and improving the drilling quality. The heat conductive sheet layer is made of a high thermal conductivity material, which can quickly conduct the heat generated by the drill bit and effectively dissipate it through other parts of the pad, thereby preventing local overheating from damaging the drill bit and the pad. The thermal resistance material layer adopts high-efficiency aerogel or thermal insulation foam and other materials, which effectively prevents the transfer of heat, protects other parts of the pad from high temperature, and also prevents the heat from damaging the pad itself.
