Benefits or advantages of HDI PCB

Following are the benefits or advantages of HDI PCB:
➨It allows more components in small board areas as HDI PCBs are populated on both the sides. Hence HDI PCB offers denser trace routing.
➨It decreases power usage as a result long battery life can be achieved.
➨It offers light weight and small size PCBs.
➨Fast signal transmission with enhanced signal quality can be achieved using HDI PCB.
➨It offers space to mount more components compare to traditional PCB.

What is a HDI PCB?

HDI stands for High Density Interconnector. A circuit board which has a higher wiring density per unit area as opposed to conventional board is called as HDI PCB. HDI PCBs have finer spaces and lines, minor vias and capture pads and higher connection pad density. It is helpful in enhancing electrical performance and reduction in weight and size of the equipment. HDI PCB is the better option for high-layer count and costly laminated boards.

Regarding the electrical needs of high-speed signal, the board should have various features i.e. high-frequency transmission capability, impedance control, decreases redundant radiation, etc. The board should be enhanced in the density because of the miniaturization and arrays of the electronic parts. In addition, to the result of the assembling techniques of leadless, fine pitch package and direct chip bonding, the board is even featured with exceptional high-density.

Innumerable benefits are associated with HDI PCB, like high speed, small size and high frequency. It is the primary part of portable computers, personal computers, and mobile phones. Currently, HDI PCB is extensively used in other end user products i.e. as MP3 players and game consoles, etc.

3. Advantages:

The most common reason for using HDI technology is a significant increase in packaging density. The space obtained by finer track structures is available for components. Besides, overall space requirements are reduced will result in smaller board sizes and fewer layers.

Usually FPGA or BGA are available with 1mm or less spacing. HDI technology makes routing and connection easy, especially when routing between pins.
