HDI Printed Circuit Boards - High Density Interconnect PCB Technology


With the development of society, the progress of technology comes from people's constant pursuit of life and their yearning for higher quality of life. Personal consumer electronic products such as notebook computers, personal computers and mobile phones require lighter weight and smaller volume, while smaller volume requires smaller design accuracy and higher density. At the same time, the quality and speed of interconnection technology should be better. This requires designers who make these products to design better components to improve electrical performance, such as circuit boards and so on.

In order to manufacture PCB products of this kind, PCB manufacturers need more advanced manufacturing technology. Of course, from the point of view of product cost, it needs lower cost. This seems contradictory, but HDI PCB can solve this problem very well. HDI PCB has numerous advantages, such as high speed, small size and high frequency.


HDI PCB is the better option for high-layer count and costly laminated boards.




What is a HDI PCB, The definition of HDI PCB


HDI stands for High Density Interconnector, HDI Printed Circuit Board. 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.


High density interconnect (HDI) PCBs represent one of the fastest-growing segments of the Printed Circuit Board market. Because of its higher circuitry density, the HDI PCB design can incorporate finer lines and spaces, smaller vias and capture pads, and higher connection pad densities. A high-density PCB features blind and buried vias and often contains microvias that are .006 in diameter or even less.

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.

There were a lot of different names for the PCB with such structures. For example, it was called SBU (Sequence Build up the Process) in European and American industry as the program production is in the constructive mode of sequence. It was called MVP (Microvia Process) in Japanese industry because the hole of such products is much smaller than the previous one. It was also called BUM (Build up Multilayer PCB Board) because the traditional multilayer is known as MLB (Multilayer PCB Board).In order to avoid confusion, IPC Printed Circuit Association proposed to call it HDI (High Density Interconnection Technology) as the common name, but it can not reflect the characteristics of the circuit board. So the majority in the PCB industry define such products as HDI PCB.

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.

HDI PCBs take advantage of the most recent technologies existing to amplify the functionality of circuit boards by means of the similar or little amounts of area. This development in board technology is motivated by the tininess of parts and semiconductor packages that assist superior characteristics in innovative new products like touch screen tabs.

HDI PCBs are described by high-density features comprising of laser micro-vias, high performance thin materials and fine lines. The better density allows extra functions per unit area. These types of multifaceted structures give the required routing resolution for large pin-count chips which are used in mobile devices and other high technology products.

The placement of the parts on the circuit board needs extra precision than conservative board design due to miniature pads and fine pitch of the circuitry on the circuit board. Leadless chips require special soldering methods and additional steps in the assembly and repair process.

The lesser weight and size of the HDI circuitry means the PCBs fit into the little spaces and have a smaller amount of mass than conservative PCB designs. The smaller weight and size even signifies that there is lesser chance of harm from mechanical shocks.



Consumer Driven Technology


The via-in-pad process supports more technology on fewer layers, proving that bigger is not always better. Since the late 1980's we have seen video cameras using cartridges the size of a novel, shrink to fit in the palm of your hand. Mobile computing and working from home pushed technology further to make computers faster and lighter, allowing the consumer to work remotely from anywhere.

HDI Technology is the leading reason for these transformations. Products do more, weigh less and are physically smaller. Specialty equipment, mini-components and thinner materials have allowed for electronics to shrink in size while expanding technology, quality and speed.

Benefits of HDI PCB Technology with Micro Circuits:


The evolution of high-density PCB technology has given engineers greater design freedom and flexibility than ever before. Designers using HDI high density interconnect methods now can place more components on both sides of the raw PCB if desired. In essence, an HDI PCB gives designers more space to work with, while allowing them to place smaller components even closer together. This means that a high-density interconnect PCB ultimately results in faster signal transmission along with enhanced signal quality.

HDI PCB is widely used to reduce the weight and overall dimensions of products, as well as to enhance the electrical performance of the device. The high-density PCB is regularly found in mobile phones, touch-screen devices, laptop computers, digital cameras and 4G network communications. The HDI PCB is also prominently featured in medical devices, as well as various electronic aircraft parts and components. The possibilities for high-density interconnect PCB technology seem almost limitless.



  • Shorter PCB manufacturing lead times and improved device performance for Flip Chip, BGA, MCM, SIP technologies and medical devices.


  • Allows utilization of technologies that require ultra thin cores, fine line geometries and alternative via technologies for enhanced thermal transfer in the case of a thermal PCB.


  • Allows utilization of the technologies that require 20um circuit geometries, 30um dielectric layers, 50um laser vias and 125um bump pitch processing.


  • Allows reducing the [time to market" equation by combining the process capabilities with a strong comprehension of high speed digital and high frequency RF PCB package requirements.


  • Increases the area for the PCB designer provider to place circuit components as the components are decreased in size and spaced much closer together. This also improves faster signal transmission and reduced signal loss.



HDI PCB Applications


HDI PCBs are appropriate for a wide range of industries. As mentioned above, you'll find them in all types of digital devices, like smartphones and tablets, where miniaturization is key to the effective application of the product. You can also find high-density interconnect PCBs in automobiles, aircraft and other vehicles that rely on electronics.

One of the most critical areas where the high-density PCB is making huge inroads is in the medical arena. Medical devices frequently need small packages with high transmission rates that only HDI PCBs can supply.

For example, an implant needs to be small enough to fit in the human body, but any electronics involved in that implant absolutely must efficiently allow for high-speed signal transmission. Here, the HDI PCB indeed is a godsend. HDI PCBs can also be useful in other medical equipment, like emergency room monitors, CT scans and much more.

No matter your industry, you're probably already getting some ideas about how high-density interconnect PCBs can make the electronics you produce or use even better - get in touch with us PCBCart to discuss it. We'll let you know if you're on the right track and help you decide exactly how beneficial an HDI PCB can be to your industry. Then, you can determine whether or not to take the next step.
