HDI PCB Mid-Year Sale
In order to return the trust of new and old customers to Guangzhou Jujin Technology, we decided to carry out a mid-year promotion in June.
What are the factors that affect PCB impedance?
In general, the following factors affect the characteristic impedance of a PCB: dielectric thickness H, copper thickness T, width of the alignment W, spacing of the alignment, dielectric constant Er of the material selected for the stack, and thickness of the solder resist. In general, the higher the dielectric thickness and line spacing the higher…

PCB impedance and loss change how to calculate, do you know all?
In general there are two main rules to follow for stacked design: 1. Each alignment layer must have an adjacent reference layer (power or ground); 2. The adjacent main power and ground layers are to be kept at a minimum distance to provide a large coupling capacitance. Here is an example of a stack from…
