What is the impact of analyzing the circuit board on the material during PCB processing?
The stability of multi-layer PCB material standard is the primary factor affecting the positioning accuracy of the inner layer. It is also necessary to consider the influence of the thermal expansion coefficient of substrate and copper foil on the inner layer of Multilayer PCB. From the analysis of the physical properties of the substrate used, the laminates contain polymers, and its primary structure will change at a certain temperature, which is commonly known as the glass transition temperature Tg.
During the processing of BQC circuit board in Shenzhen, the selection of raw materials is also very important. We should conduct in-depth analysis on the functions of raw materials to ensure that the raw materials meet certain skill requirements and bring assistance to later processing. In the future, the skills will continue to develop, and its production method will become more advanced over time to ensure that the standard and accuracy of the circuit board meet the requirements.
