HDI PCB: Defination, Features And Its Amazing Benefit

Release time: 09/11/2017

The abbreviation HDI represents High-Density Interconnector. It is a circuit board with per unit area having a higher wiring density as opposed to the traditional board is known as HDI PCB. Now, HDI PCBs have finer lines and spaces, minor vias as well as capture pads and even higher density of connection pad. It is helpful in improving electrical overall performance and reduction in size and weight of your equipment. HDI PCB is just the better alternative for costly laminated boards and high-layer count.

Concerning the electrical requirements of a high-speed signal, its board should have different features that are high-frequency transmission capability, decreases excessive radiation, impedance control, and so on. The board should be improved in the density because of the arrays and miniaturization of the parts of the electronics. In addition to the assembling techniques of a leadless result, fine pitch package as well as direct chip bonding, the HDI PCB board is featured with an exceptional high-density.

There are so many innumerable advantages related to HDI PCB, like the small size, high speed, and high frequency. It's the main part of personal computers, portable computers, and mobile phones. Presently, HDI PCB is highly used in another end-user item that is, like game consoles and MP3 players, and so on.

HDI PCBs take some advantages of the latest existing technologies to amplify the circuit boards functionality using the similar or even little amounts of area. Such technological development in a board is motivated by the parts tininess as well as semiconductor packages which help superior characteristics in new innovative products such as touch screen tabs.

Now, HDI PCBs are usually described by its high-density features consisting of high-performance materials, laser micro-vias, and fine lines. Its better density permits additional functions per unit area. Such forms of multifaceted structures provide the needed routing resolution for big pin-count chips that are utilized in high technology products and mobile devices.

The placement of its parts on the circuit board requires extra precision compared to conservative board design because of miniature pads as well as the fine pitch of its circuitry on the circuit board. Also, leadless chips need special soldering ways and extra steps in the repair and assembly process.

The lesser size and weight of the HDI circuitry imply the PCBs will fit into the small spaces and get a smaller level of mass compared to conservative designs of the HDI PCB. The smaller size and weight signifies that there's a lesser chance of being harmed from mechanical shocks.
