Why can’t you do multilayer PCBs well?

Multi-layer PCBs are generally defined as high multilayer PCBs with 10 – 20 layers or more, which are more difficult to process than traditional multilayer PCBs and their quality and reliability requirements are high, mainly used in communication equipment, high-end servers, medical electronics, aviation, industrial control, military and other fields. In recent years, the market…

HDI PCB

High density interconnect PCBs are a way to leave more space on a printed circuit board to increase efficiency and speed up transfer speeds. It’s relatively easy for most aggressive companies using printed circuit boards to understand how this will benefit them. High Density Interconnect HDI PCBs represent one of the fastest growing segments of the…

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…
