What is HDI PCB board?

HDI (High Density Interconnect) PCB is a type of circuit board that uses advanced technology to increase the number of interconnections (or connections) in a given area. This is achieved by using smaller and more closely spaced components, as well as by using advanced manufacturing techniques such as laser drilling and microvia technology.

HDI PCBs have a higher component density than traditional PCBs, which allows for more functionality and a smaller overall size. This makes them well-suited for a wide range of applications, such as smartphones, tablets, and other portable devices, as well as for use in medical, automotive, and aerospace systems.


The main advantages of HDI PCBs include:


Higher component density: Allows for more functionality in a smaller space

Improved electrical performance: Smaller components and closely spaced connections result in improved signal integrity and faster signal transmission

Increased reliability: Advanced manufacturing techniques and materials result in a more robust and reliable product

Reduced size and weight: Allows for more compact and lightweight devices

The main disadvantage of HDI PCBs is that they are more complex and expensive to manufacture than traditional PCBs, which can make them less suitable for some applications. Additionally, the smaller components and closely spaced connections can make them more difficult to repair and rework.


Overall, HDI PCBs are an important technology for a wide range of applications, and will likely continue to play a key role in the development of new and advanced electronic devices in the future.
