description: "Discussion on \"How to Choose the Right HDI Order: 1-N, 2-N, Any-Layer—Higher Isn't Always Better\". A practical guide to HDI order selection in PCB design. Learn the differences between 1-N, 2-N, 3-N, and any-layer HDI, when each is sufficient, and how order selection affects cost, lead time, and yield. Based on AnyPCBA's small-to-medium volume manufacturing experience."
