High-Density Interconnect (HDI) Printed Circuit Board (PCB)
PCBs are commonly used in almost all electrical devices. Some devices have complex functionality and need more efficiency and high performance so; technology evolves the PCB to HDI PCBs to enhance the functionality of complex electronic devices. HDI is the latest type of PCB or technology in PCB, which makes the small size, and lightweight of board as compared to the common type of PCBs. In this article, we will discuss all “High-Density Interconnect (HDI) Printed Circuit Board (PCB) (HDI PCBs”.
High-Density Interconnect (HDI) PCBs
High-Density Interconnect (HDI) is a new technology in the field of PCB manufacturing. HDI is a technology that makes PCB small-sized and light weighted as compared to a common type of PCB. HDI PCB is the PCB board, which have microvias, blind and buried vias, high signal performance, compact size, and lightweight. They are used in complex electronic devices.
The electronic components on the HDI PCBs are too much closer to each other, which enables the high connection between the components and the high performance of the PCB.
High-Density Interconnect PCB’s Capabilities
HDI PCB manufacturing needs a high level of technical expertise and modern state-of-art equipment for proper precision. Therefore, HDI PCB Manufacturers should have a high level of technical expertise and knowledge to use the equipment in HDI PCB manufacturing.
HDI PCB should have high-tech capabilities that are mentioned below:
- Laser drilled microvias
- Stacked microvias
- Via-in-pad
- Laser Direct Imaging
- Fine Pitch
- High Performance
- High Efficiency
- Improved Reliability
Advantages of High-Density Interconnect PCBs
HDI PCBs are more efficient as compared to a common type of PCB. Some of the benefits of HDI PCBs are mentioned below:
- Have the ability to do more with less
- Continuously refined for better accuracy due to the copper-etching technology
- With HDI, it becomes achievable to pack more functionality of numerous PCBs in a single PCB, which is HDI PCB
- Reducing the distance between the device and trace space, HDI PCB enables manufacturers to use many transistors for making it perform better
- HDI PCBs lower the power consumption of the devices in which they are used
- Signal reliability is also improved due to the small distance of connections and low power consumption
- It also enables other performances like the stable voltage, minimal stub, closer ground planes, and much more
- HDI PCB boards are cost-efficient when properly planned due to the short number of required layers, small size, and less required boards
- It is manufactured rapidly and marketed fastly due to the simple and easy placement of components on the board
- It has high performance and efficiency as compared to a common type of PCB
- HDI PCBs are more reliable as compared to a simple sort of PCB
Uses of High-Density Interconnected PCBs
HDI PCBs are frequently used in electronic devices, machines, tools, and applications these days. The major uses of HDI PCBs are mentioned below:
- Commonly used in complex devices that demand high performance
- Used in mobile phones, laptops, computers, touch-screen devices, computers, 4G and 5G networks, and in many other devices
- HDI PCBs are also used in Automotive and Aerospace industries like modern cars
