Production method of ceramic filling type hydrocarbon resin copper-clad plate

Abstract

The invention relates to a production method of a ceramic filling type hydrocarbon resin copper-clad plate. The production method comprises the following steps: carrying out surface treatment on a ceramic filler by using a silane coupling agent; weighing the surface-treated ceramic filler, hydrocarbon resin and a curing agent in proportion, adding a proper amount of solvent to adjust the viscosity, and fully mixing by using a mixing device; defoaming the mixed slurry by using a slurry defoaming device; performing silk-screen printing on the de-foamed slurry on the surface of a copper foil, performing low-temperature drying after printing is completed, repeating the silk-screen printing process for multiple times until the required thickness is reached, and covering the surface with the copper foil; and carrying out hot pressed sintering on the two-sided copper foil-coated plate to prepare the ceramic filling type hydrocarbon resin copper-clad plate. The problem that an existing carbon-hydrogen resin copper-clad plate filled with glass fiber cloth inorganic ceramic powder has electrical property difference in the X direction and the Y direction is solved. The ceramic filling type hydrocarbon resin copper-clad plate is widely applied to the modern microwave electronic communication field of high-end electronic products such as microwave communication, active phased array radars, unmanned vehicle-mounted radars and the like.

Description

technical field [0001] The invention belongs to the field of electronic components, specifically, to the field of microwave electronic components, and more specifically, to the field of ceramic materials for microwave electronic components. Background technique [0002] With the development of high-end electronic products such as microwave communication, active phased array radar, and unmanned vehicle radar. The design of high-frequency signal transmission characteristics requires that the microwave circuit board must have low dielectric, low loss, low thermal expansion coefficient, and good processing and dimension stability. Hydrocarbon resins are mainly composed of polybutadiene, polystyrene, polypropylene, etc. Material composition, its own dielectric constant is 2.4-2.8, dielectric loss is between 0.0002-0.0006, and its electrical properties are excellent. It is often used to process copper-clad laminates. Thermosetting hydrocarbon polymers are obtained through cross-li...
