For example, the expansion and contraction of the board material; differences in the expansion coefficients of different materials at high temperatures can lead to misalignment of inner layers, affecting signal integrity. Understanding material properties in advance and compensating for these in the design can effectively avoid such problems. Furthermore, processing details such as aspect ratio also need to be weighed in conjunction with actual process conditions. This article shares some experience in multilayer board design to help..."}
