HDI basically stands for a High-Density Interconnector. These boards have higher wiring density per unit area as compared to a conventional circuit board. These PCBs consist of finer spaces and lines, have minor vias, and shrunk capture pads while offering a higher connection pad density. In the modern world, PCB’s are used widely across numerous applications. PCBs are proven to be the best alternatives to the usage of wires and are deemed crucial in making circuit boards.

Why is the HDI PCB definition important?

HDI PCB definition is essential to let the manufacturers know about its benefits. While comparing it with the conventional PCB Board, there are just a few people who aren’t aware of HDI PCB. Due to the advancement in technology over the years, the smartphone has become an essential part of the day to day operations and is becoming more normal than ever. When asked a smartphone designer, what kind of PCB board is used in the making of these smartphones? He would say the HDI PCB board, even iPhone uses it.

What is HDI PCB an abbreviation of?

Distinct from MCPCB, HDI PCB does not have many names. Many people don’t know why it is called HDI. As a matter of fact, HDI PCB is an abbreviation of the High-Density Interconnecting Printed Circuit Board. The full name of HDI PCB is used very often, and most people go only with the capitalized abbreviation.

What is the density of HDI PCB, and how is it different from conventional boards?

To get around the concept of difference and what makes the first distinct from the other, we have to take into account the density. Yes, HDI PCB encompasses higher wiring density per unit area. HDI PCB’s are denser as compared to the conventional boards.

What is new about the making of the HDI PCBs?

It can be noted that in mobile phones, the assembly space covers a small area. This makes it mandatory to make phones more exquisite and more delicate. Additionally, HDI PCB designs have a smaller vase and contain tiny capture pads that are higher than the connection pads. In the making of traditional PCB design, there was a whole lot of experience from before that helped. But in the making of HDI PCB board design, past experiences are not enough; you have to take into account other factors too.


What is the manufacturing process of an HDI PCB?

While manufacturing an HDI PCB, every chip is made through a microwave. Numerous insulation materials are used to sequentially laminate different metal cores. The board is hard-wired and is very dense, which makes it more durable. Due to its durability, it is also the number one choice of phone manufacturers too.

Why chose HDI PCB over other traditional boards?

As is indicated above that an HDI PCB design process is trickier and challenging than traditional PCBs. Due to its durability and micro insulation, it is the top choice of many mobile phone manufacturers. HDI PCB is not only convenient and durable, but it also enhances the electrical performance of the devices. It is lightweight and covers a small area. It is cheap, and the best alternative as compared to other conventional PCBs.

What is the best feature of our HDI PCB?

The best feature of our HDI PCB is our customer-driven technology. Due to advancements in technology, we have adopted the via-in-pad process, through which it is possible to support more technology on a few layers, which proves that bigger is not always better. In the past, computers were massive, and video cameras used cartridges the size of a torch battery. But now things have changed, and this is what we did. We adapted and improvised. Now were are making computers faster and lighter, making it easier for customers to work remotely. Our products perform more, weigh less, and are physically smaller than what our competitors are offering.

What are the primary HDI benefits?

As the demands of customers are constantly changing, technology is advancing too. Using the HDI technology, the designers can now place more components on every side of the PCB’s. By using blind via technology and multi via processes including via in pad, designers can now place components that are smaller in size closer than ever. Because of the shrunk component size, the PCB is now smaller than usual. This doesn’t only mean that the signals are transmitted quickly, but there is a lower chance of signal loss and crossing delays.

Are the HDI PCB’s really cost-efficient?

Although some of the components of the products that the customers want are shrunk in size, quality remains the most essential factor for the customer, other than the price. It is now possible to shrink an 8 layer through-hole to a 4 layered HDI micro via technology-packed PCB. All of the processes done through the state of the art technology, however, increase the cost of the HDI PCB, but the design and proper reduction in layer count lower the cost in material sq. Inches. So yes, HDI PCB’s are more cost-effective than traditional PCB’s.

List the benefits of acquiring an HDI PCB over a conventional PCB?

Countless benefits are attached to acquiring an HDI PCB over the traditional PCB. HDI PCB’s are fast, smaller in size, have a better frequency, and very cost-effective. That is why these boards are preferred while making mobile phones, personal computers, and laptops. These days, HDI PCB’s are excessively being used in the making of other end-user products such as mp3 players and gaming consoles. Such development is inspired by the semiconductor packages that assist superior characteristics in other innovative products such as touch screen tabs. An HDI PCB not only boasts about its superior quality but is also proven to decrease power usage. This leads to healthier battery life in portable and conventional devices. HDI circuit boards have reduced thermal degradation, which prolongs the life of the device. Many computer manufacturers have also endorsed HDI PCB’s over conventional circuit boards.
