How to Optimize Layer Stack-Up in HDI PCB Boards
With the introduction of the HDI stackup, a cutting-edge technique in multilayer PCB design, PCB designers should be able to create increasingly complex, smaller boards in the years to come. Establishing your project's needs precisely is the first step in designing a PCB stackup. Determining the number of layers required is the first stage; this depends on the circuit's complexity, signal density, power distribution requirements, and if the design calls for RF or high-speed signals. In the late 1980s,......

Blind vs Buried Vias: A Comprehensive Guide for PCB Design
A printed circuit board (PCB) is made up of layers of copper foil circuits stacked on top of each other, and the connections between different circuit layers rely on vias. If the holes drilled by a drilling machine or laser are left as is, they will not conduct electricity, because the surface of the original drilled hole is only resin, which is not conductive. Therefore, a layer of conductive material (usually copper) must be plated on the surface of the drilled hole. In this way, current propagates ......

Comprehensive Guide to HDI PCBs: Design, Advantages, and Applications
High Density Interconnect (HDI) printed circuit boards (PCBs) are circuit boards with a higher wiring density per unit area than traditional PCBs. HDI PCBs have denser interconnections and components, finer lines and spaces, and higher connection pad density. They also have smaller vias and traces, and higher layer counts. A single HDI board can accommodate the functionalities of multiple boards previously used in a device. HDI PCBs are a preferred choice for high-layer and expensive laminated boards.......
