Intelligent mobile phone integrated circuit board based on graphite film coating and preparation process

Abstract

The invention discloses a smartphone integrated circuit board based on a graphite film coating, which comprises a supporting plate layer, a copper-clad plate layer is fixedly arranged on the supporting plate layer, an element layer is fixedly arranged at the upper part of the copper-clad plate layer, a power supply layer and a signal layer are sequentially arranged at the lower part of the copper-clad plate layer, a substrate is fixedly arranged at the bottom of the signal layer, and a graphite film coating is arranged on the substrate. A graphite film layer is arranged at the bottom of the substrate, the power supply layer is electrically connected with the copper-clad plate layer through a first connecting column, and the copper-clad plate layer is electrically connected with the signal layer through a second connecting column; according to the integrated circuit board, isolation can be achieved by arranging the two isolation layers in the integrated circuit board, connection stability and electrification can be improved through the connecting columns and the clamping connectors, and heat dissipation treatment can be effectively conducted on the integrated circuit board through the arrangement of the heat conduction silicone grease layer and the graphite film layer.

Description

technical field [0001] The invention relates to the technical field of collecting circuit boards, in particular to a smart phone integrated circuit board based on graphite film coating and its preparation process. Background technique [0002] With more and more functions required by electronic products, the structure of PCB circuit boards is also becoming more and more complex. Due to the space limitation of PCB circuit boards, circuit boards are gradually "evolving" from single-layer to double-layer and then to multi-layer. An integrated circuit board is a carrier for carrying integrated circuits. But it is often said that the integrated circuit board also brings the integrated circuit. The integrated circuit board is mainly composed of silica gel, so it is generally green in color. The integrated circuit board uses semiconductor manufacturing technology to manufacture many transistors, resistors, capacitors and other components on a small single crystal silicon wafer, a...
