Double panel, as a common type of circuit board, its manufacturing process and quality control are crucial. High quality double-sided boards not only ensure the stable operation of electronic devices, but also extend their service life. Next, let's learn about the manufacturing process and quality control of double-sided boards.

Firstly, the manufacturing process of double-sided boards mainly includes steps such as pressing, drilling, electroplating, etching, etc. Pressing is the process of bonding two layers of copper foil and one layer of insulation material together through high temperature and high pressure. Drilling is the use of laser or mechanical methods to drill the required holes on the board for the installation of components and circuit connections. Electroplating is to enhance conductivity and prevent oxidation, usually by depositing a layer of metal on the hole wall and circuit surface. Etching is the process of removing excess copper foil through chemical agents to form the final circuit pattern.

Secondly, quality control is an indispensable part of the double-sided board manufacturing process. Each process requires strict testing to ensure that all product indicators meet the requirements. For example, during the pressing process, it is necessary to check the thickness and uniformity of the insulation material; During the drilling process, it is necessary to check the aperture and positional accuracy; During the electroplating process, it is necessary to test the thickness and adhesion of the coating; During the etching process, it is necessary to check the accuracy and integrity of the circuit.

Finally, in order to ensure the quality of double-sided boards, manufacturers will also conduct a series of reliability tests, such as heat resistance tests, pressure resistance tests, bending tests, etc. These tests can effectively evaluate the performance and lifespan of the dual panel in practical use, ensuring its stable operation in various harsh environments.

In summary, the manufacturing process and quality control of double-sided boards are key to ensuring their performance and reliability. Only through strict standards and testing can high-quality double-sided boards be produced to meet the needs of various electronic devices.
