If there is one trend when it comes to electronic devices, it has to be that of miniaturization. The size of electronic devices is shrinking and their complexity is on the rise. What this, in turn, means is the increase in demand of small PCBs. There is, therefore, a corresponding increase in the technology that can facilitate these small sized PCBs.
This is the exact reason why High Density Interconnect or HDI, as it is popularly called, is becoming increasingly relevant in today’s times.
Essentially, HDI technology is a result of evolution in component packaging that facilitates the construction of small boards that can have a large number of components per square inch. Simply put, an HDI PCB, therefore, has higher wiring density per unit area, as opposed to a conventional board. HDI printed circuit boards with one or all of the following:
In fact, it is the Microvias that have a huge role to play when it comes to the capabilities of HDI printed circuit boards. Since smaller vias can be close to each other, the board requirement is small. Also, space is easily freed up for additional components. With Microvias also having smaller aspect ratios that through-hole vias, the reliability quotient of HDI boards is far higher.
A typical PCB has one or two layers, while multilayer PCB can have up to 20 layers depending on their complexity. When it comes to HDI PCB, however, it could have as many as 40 layers which have densely mounted components, fine lines and micro vias. Some of the advantages of using HDI PCBs include:
HDI PCBs are used in a wide range of industries, especially where miniaturization is prevalent. These would include digital devices, automobiles, aircrafts and more.
Another area where HDI PCB Fab finds a lot of application is to do with medical devices. With the need for small devices with high transmission rates, HDI PCBs fit the bill. This is especially true of implants but also of other medical equipment such as CT scans, MRI equipment and more.
