Why HDI PCB Manufacturing Starts Long Before the First Hole Is Drilled

High-density interconnect (HDI) PCB manufacturing emphasizes meticulous planning even before physical production begins, unlike conventional PCBs. This early focus on engineering review is crucial because HDI technology involves complex structures like microvias and blind vias that require precise design and simulation to ensure successful outcomes. Understanding this shift highlights how advanced PCB technologies demand more sophisticated processes and early design phases, impacting everything from production timelines to costs.
