[0042] Example
[0043] S1: Select the double-sided copper plate 100 to be cut into different sizes of workpieces according to the production needs, and choose the established workpiece size according to the size to avoid waste and increase unnecessary costs;
[0044] S2: Process the copper foil 120. Before being combined with the outer layer, the copper foil 120 must be oxidized to form a fine uneven surface, and the oxidation treatment time is 35 minutes;
[0045] S3: Paste the photosensitive dry film on the double-sided copper plate 100 as the inner layer, and then close the film used to make the inner layer wiring, expose, and then perform the development process, leaving only the wiring required Where, by etching, remove the unnecessary copper foil 120;
[0046] S4: The double-sided copper plate 100 after oxidation treatment, the outer layer copper plate 110 is combined with the outer layer 110, in a vacuum state, while heating, while being compressed by a laminator, the pressure...

The invention belongs to the technical field of manufacturing processes, and particularly relates to a high-frequency high-speed and high-density circuit board manufacturing process. The high-frequency high-speed and high-density circuit board manufacturing process comprises the following steps of S1, selecting a double-sided copper plate, cutting the double-sided copper plate into workpieces withdifferent sizes according to production requirements, and selecting a set workpiece size according to the sizes so as to avoid wastes and the increased unnecessary cost; S2, processing the copper foil; and forming a fine concave-convex surface on the copper foil through the oxidation treatment of the copper foil and before the synthetization of the outer layer. According to the high-frequency high-speed and high-density circuit board manufacturing process, the combination mode of a lining plate and a lining frame is adopted in the manufacturing of the circuit board. The lining plate is used for mounting the bottom and the top of the circuit board. Through the cooperation of the lining frame, the circulation speed of the airflow is improved through the generation of gaps. Meanwhile, the heat of the lining plate is guided. An arc plate with arc plate holes is utilized, so that the heat dissipation speed is increased. The use purpose of the high-frequency, high-speed and high-density circuit board is achieved. The stability of the circuit board is improved under the condition of no external energy consumption.
Description
technical field [0001] The invention relates to the technical field of manufacturing technology, in particular to a high-frequency, high-speed, high-density circuit board manufacturing technology. Background technique [0002] Circuit boards are divided into three categories: single-panel, double-panel, and multi-layer circuit boards according to the number of layers. The circuit board makes the circuit miniaturized and intuitive, and is suitable for mass production of fixed circuits and optimized electrical layout. makes an important impact. [0003] With the miniaturization and digitization of electronic products, printed circuit boards are also developing towards high density and high precision. [0004] In some high-frequency and high-speed environments, how to ensure the stability and life of the circuit board has always been one of the topics of discussion and research. Under the high-frequency, high-speed and high-density use requirements of the existing circuit boar...
