High Density Interconnect (HDI) PCB Board Manufacturing service

OVERVIEW

Why is HDI PCB widely used? With the development of society, the progress of technology comes from people’s constant pursuit of life and their yearning for a higher quality of life. Personal consumer electronic products such as notebook computers, personal computers, and mobile phones require lighter weight and smaller volume. In contrast, a lower amount requires more modest 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.

To manufacture PCB products of this kind, PCB manufacturers need more advanced manufacturing technology. Of course, for product cost, it needs a lower price. 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 the high-layer count and costly laminated boards.

What is a HDI PCB ?

The Definition of HDI PCB Board

HDI stands for High-Density Interconnector, HDI Printed Circuit Board. A circuit board that has a higher wiring density per unit area, as opposed to the conventional board, is called HDI PCB. HDI PCBs have more unique spaces and lines, minor vias, and capture pads and higher connection pad density. It helps enhance electrical performance and reduction in weight and size of the equipment.

High density interconnects (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 more beautiful 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 micro vias that are .006 in diameter or even less.

Regarding the electrical needs of high-speed signals, 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. Also, to the result of the assembling techniques of leadless, excellent pitch package, and direct chip bonding, the board is even featured with exceptional high-density.

HDI PCB in Different Countries

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 the European and American industry as the program production is in the constructive mode of sequence. It was called MVP (Microvia Process) in the Japanese sector 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).To avoid confusion, IPC Printed Circuit Association proposed to call it HDI (High-Density Interconnection Technology) as the common name. Still, it can not reflect the characteristics of the circuit board. So the majority in the PCB industry define such products as HDI PCB.

Benefits of HDI PCB Technology with Micro Circuits

High-density Circuit Board Technology Gives Engineers More Room to Play

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 PCBs Help Improve the Electrical Performance of the Equipment

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.

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.
