ABOUT HDI PCB
The HDI application is one of the fastest-growing technologies today. The acronym stands for High-Density Interconnect, which comes with several interconnection points enclosed within a small space that result in reduced circuit boards – though functionally not affected!
In other words, a PCB with about 120-160 pins per square inch is an HDI. So the design of the HDI integrates versatile routing and density component placement. This PCB type became popular because it made micro via technology famous – an ideal option for blind vias, micro vias, or buried vias.
THE 3 WAYS TO DESIGNING A SUCCESSFUL HDI PCB
There are three ways you can design HDI prototyping boards that will yield success every time.
And they are as follows:
1. Manufacturing Process
Before you begin your HDI PCB design, you first need to understand the HDI manufacturing process parameters. And to do that, you need to consider three factors:
Aperture Ratio
To have a successful HDI PCB, you must know the aperture ratio that is appropriate for your fabrication.
For the best results, keep your aperture size proportional to how thick or thin you want your board.
Stack
The stack-up of the HDI PCB has to get classified based on specific types. For instance, Non-stacked 2-HDI (with buried holes), Stacked and resin-filled 2-HDI, 1 stacked and nonresin filled2 -HDI with buried holes).
Process Flow
The process flow for the 4-layer and 6-layer HDI boards are very similar to standard PCBs, with one major difference: drilling holes sequencing.
2. Layout
When you use HDI PCB layouts in your projects, it’s important to be aware of the maintainability and stability.
3. Tracking
You must consider the tracking process, including the tracking’s consistency, the least line width, and regulating safe spacing.
HDI PCB CAPACITY (UP TO 32 LAYERS)
The Different Types of
HDI PCB Structures
We can produce up to 32 layers at a time. So you’ve got plenty of options depending on your specific needs! We created this table that breaks down all our HDI PCB structures for quick reference:
HDI PCB Structures | The Various categories of Micros Vias | Large-Scale Production | Small to Medium-Scale Production | Prototype | Available |
---|---|---|---|---|---|
1+N+1 | Blind vias | Yes | Yes | Yes | Over 4 layers |
2+N+2 | Blind/Buried staggered vias | Yes | Yes | Yes | Over 6 layers |
2+N+2 | Blind/Buried stacked vias | Yes | Yes | Yes | Over 6 layers |
3+N+3 | Blind/Buried stacked vias | / | Yes | Yes | Over 8 layers |
3+N+3 | Blind/Buried stacked vias | / | / | Yes | Over 8 layers |
WHAT IS THE FUTURE FOR HDI PCB?
HDI PCBs are creating a lot of possibilities in a wide range of industries. And it can only develop as time passes.
So, it’s a technology that you should consider—especially if you need something that will save you time and boost your efficiency. Plus, the demand for the HDI PCB increases regularly. So, we can tell that it’s promising.

THE BENEFITS OF USING HDI PCB
Better Signal Veracity
- HDI integrates with a blind via tech and via-in-pad to put PCB components together without cutting down the signal path length.
- HDI also eliminates Via stubs, which limits signal reflection and boosts the quality of signals.
Affordable
- An 8-layer PCB can reduce to a 6-layer PCB. By doing so, you'll still maintain an exceptional quality level and brightness in your product.
Compact Design
- The grouping of micro, blind, and buried vias reduces the requirement for board space.
Better Signal Veracity
- The integration of stacked vias makes HDI boards highly resistant to extreme environmental conditions because of the super shield.
Extraordinary Adaptability
- The HDI board is a perfect solution for those looking to save space and weight while still maintaining excellent performance.
THE DIFFERENCE BETWEEN STANDARD AND HDI PCBs
The standard PCBs use through-holes, which means they have a high stray capacitance and a colossal discontinuity in impedance.
The HDI design employs buried vias and small blinds. These two factors significantly reduce stray inductances and capacitances, which in turn provides excellent signal integrity performance. In addition to that, other vital differences between the standard PCB versus the high-density board are:
APPLICATIONS OF THE HDI PCB
Automotive
- Technology is having a large effect on the automotive industry. It has pushed engineers to work towards making cars more enjoyable for drivers and saving space in vehicles.
Industries
- Your VR headset, tablet, smartwatch, laptop entertainment systems, smartphone, or home appliances. All these gadgets have an HDI
Health Care Sector
- HDI PCBs have provided great possibilities for the medical field. For example, they play a large role in diagnosing diseases and are an excellent source of equipment for pacemakers such as those used to diagnose heart disease.

Deitres
The relationship in monetary terms with a supplier is usually thought to be zero-sum. This means that whatever the customer or supplier saves the other losses.
However, when working with OurPCB something different happens.
The effort that this company and his dedicated employees put in reducing costs for his clients, without dismissing quality, is reflected in an exponential increase in production and therefore in the income of OurPCB. And that is called a WIN-WIN relationship, very difficult to find nowadays.

Gamboa Firmware
We have been working with OurPCB since 2006 and the treatment, quality and price have always been excellent.

Smartrek
OurPCB have manufactured our PCBs for over 7 years.
Back then, we chose them as our supplier because of their professionalism, their excellent price, but most importantly, because we felt that they really cared about their customers.
They’ve never failed us since and have helped us tremendously in growing our business.

PONCE
We've selected OurPCB among a few companies in China. We tried first other PCBA manufacturers but now OurPCB became into our main supplier. We're really glad to work with them. I also had the pleasure to work with Ellie Yao who has dedicated the right time to every question or issue I asked for.
