Multilayer Hdi Pcb Hard Gold Plating Used For Industrial Control

• Cost-effectiveness: when properly planned out, overall costs are reduced due to the lower number of necessary layers and smaller sizes/fewer number of needed boards when compared to standard PCBs.
• Faster time-to-market: Design efficiencies in HDI PCB production mean faster time-to-market. Because of the easy placement of components and vias and electrical performance, it takes a shorter amount of time to go through the design and testing process for HDI PCBs.
• Better reliability: Microvias have much better reliability than typical through holes due to the use of a smaller aspect ratio; they are more dependable than through holes, granting HDIs outstanding performance with better materials and parts.

What is an 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.
