Your Valued HDI Printed Circuit Board Supplier

High-density interconnect (HDI) printed circuit boards (PCBs) are an increasingly integral part of the PCB and electronics industries. Electronic components are becoming smaller and more lightweight but still demand ever-improving performance. To accommodate this, you need to pack more functionality into a smaller area. That’s precisely what HDI PCBs offer.

What Are HDI Printed Circuit Boards?

HDI PCBs have a higher circuitry density per unit than conventional PCBs. They use a combination of buried and blind vias, as well as microvias — those that are 0.006″ or less in diameter. High-density circuit boards are PCBs with one or more of the following features:

• Through vias and buried vias
• Through vias from surface to surface
• At least two layers with through vias
• Coreless construction with layer pairs
• Passive substrate constructions that have no electrical connection
• Alternative constructions of coreless builds with layer pairs

HDI technology in printed circuit boards and other areas has been a critical driver for developing many of the electronics we use today, especially those that have decreased substantially in size and weight in recent years. The smaller the equipment gets, the more likely it is to employ HDI technology.

The tight tolerances involved in working with HDI printed circuit boards means you need to partner with an experienced supplier. Even a small defect or layout mishap can cause significant problems. As a leading HDI printed circuit board supplier, Millennium Circuits Limited can deliver top-quality boards that have a significantly higher circuitry density than your traditional PCB.

Benefits of Using HDI Technology

HDI technology provides various advantages over other options that can improve the results of your project. With the right design and the right supplier, using HDI boards in your product can improve its overall quality and performance, as well as your customer satisfaction rate and bottom line. Other advantages include:

• Smaller Size and Lower Weight: With HDI boards, you can secure more components on both sides of the bare PCB, allowing you to get more functionality out of a smaller space and expanding the overall capabilities of the equipment. HDI technology enables you to add functionality while reducing the size and weight of your products.
• Improved Electrical Performance: A shorter distance between components and a higher number of transistors can mean improved electrical performance. These features allow for lower power consumption, which improves signal integrity. Smaller sizes correlate to quicker signal transmissions and more significant reductions in overall signal losses and crossing delays.
• Increased Cost-Effectiveness: With proper planning and manufacturing, HDI boards can be more cost-effective than other options because they require fewer raw materials due to their smaller size and the low number of layers they need. For a product that would have once required multiple traditional PCBs, you may be able to use one HDI board. You’re able to get more functionality and value out of a smaller area and less material.

• Faster Production Times: The ability to use fewer materials — and even fewer boards — combined with design efficiencies linked to HDI technology can translate to faster production times and a shorter timeframe needed to get your product to market. Components are relatively easy to place in HDI PCBs, and the high electrical performance reduces the time needed for testing and troubleshooting.
• Enhanced Reliability: The smaller aspects ratios and the high-quality construction of microvias can increase the reliability of your board and your product. The improved performance and reliability HDI PCBs provide will lead to reduced costs and more satisfied customers.
