Global PCB Connections: The Future of HDI PCBs

High-density interconnect (HDI) printed circuit boards (PCBs) transform modern electronics by providing increased functionality, reduced sizes, and enhanced performance in complex designs. They do so by using advanced techniques, such as finer line and space definitions, microvias, and additional board layers. Specialized via structures—namely blind, buried, and stacked vias—offer complex routing while conserving space. This allows for the development of highly compact electronic devices. This article delves into HDI PCB technology, the function and benefits of blind, buried, and stacked vias, and their impact on PCB performance and design.

Global PCB Connections: Following DFM Rules Leads to Better Boards

As a PCB field applications engineer, ensuring smooth communication between PCB designers and fabricators is one of my frequent challenges. A critical part of that dialogue is design for manufacturing (DFM). Many designers, even experienced ones, often misunderstand or overlook important DFM considerations. They may confuse design rules with manufacturing minimums, leading to technically feasible designs that are difficult or costly to produce. In this column, I will clarify some common DFM guidelines and help designers understand the difference between “design rules” and “minimums” while sharing best practices that will simplify the production process and ensure the highest quality PCB.
