Definition

HDI stands for High-Density Interconnect, which refers to PCBs that have higher wiring density than traditional PCBs. IL “1+N+1” designation indicates the layer structure of the PCB, with one power layer, N signal layers, and one ground layer.

Requisiti di progettazione

The design of the 6L 1+N+1 HDI mobile mainboard must meet several key requirements:

• High signal integrity to support fast data transfer rates
• Low crosstalk and interference to ensure reliable communication
• Robust mechanical properties to withstand the stresses of daily use
• Thermal management to dissipate heat effectively

Principio di lavoro

The 6L 1+N+1 HDI mobile mainboard operates by connecting various electronic components through a network of conductive pathways. These pathways are created using copper traces on the PCB layers, which are insulated from each other by layers of dielectric material. Electrical signals travel along these traces to perform the device’s functions.

Purpose and Applications

This type of mobile mainboard is commonly used in smartphones, compresse, and other portable electronic devices where space is limited but performance requirements are high. Its compact size and high functionality make it ideal for modern mobile technology.
