How Does PCBTok HDI PCB Work?
What makes it HDI is better transmission quality, as well as thermal regulation. Most HDI boards are made with advanced prepreg and laminates like Rogers material.
Because there are more electronic connections per board, per layer, this type of PCB is considered cost-effective.
HDI PCBs are also noted for their ability to enable speed. This is one of our most popular items at PCBTok.
Mobile and telecom applications are particularly well-suited to HDI PCB use. For example, most cellphone PCBs are HDI.
HDI PCB Production Process
We make PCBs using the accepted multi-step process. This includes the following.
The substrate is impregnated with epoxy resin before being baked in its entirety.
The holes are bored after the curing process (if mechanical holes are used).
In the case of Microvia PCBs, laser drilling is also an option.
Next, patterns in the HDI PCB are created using additive and subtractive processes.
The final procedures, such as attaching PCB components, are then completed after the patterns have been prepared.
Advantages of HDI PCB Use
The key benefit of HDI PCB is that it has been tested by thousands of consumers.
When it comes to circuit boards, these are the best-sellers. We can assure you that your product from us is defect-free due to our excellent quality control.

HDI PCB: The Ultimate FAQ Guide
For those who have never heard of HDI PCB, you might be interested in reading the Ultimate FAQ Guide to HDI PCB. Listed below are some of the most common questions you will need to ask yourself. Once you have answered these questions, you will be well on your way to understanding this technology. There are also some things to know before you begin. You should know that this technology is not for beginners and there are some common mistakes you should avoid.
If you need a flexible and rigid PCB, you’ve definitely heard of an HDI PCB, but what exactly is an HDI PCB? This sort of board is a combination of the two, and its production process is significantly simpler than that of other types of boards.
However, understanding the needs of your application is critical in order to select the optimal alternative. HDI PCBs are available in a variety of layouts and designs, and the design you select must match your needs as well as the needs of your product.
This type of PCB has numerous layers and requires stack-up. HDI PCBs are classified into two types: sequential and blind. The surface of the former can be patterned with various patterns to aid with the arrangement. The latter is a suitable alternative for signal routing because it reduces the size of the holes.
It is, however, less prevalent than the former. This is due to the fact that HDI PCBs require micro vias on both sides of the board.
The process of producing HDI PCBs begins with the selection of a pre-preg. After that, the layer is laminated. The hole is then mechanically or with a plate bored. The micro-vias assist in connecting the layers of the PCB. This also enables the traces and pads to be linked.
The price of this technique is determined by the number of layers and materials used. If a high-density PCB is not required, a more standard PCB can be used.
If you’re not familiar with the terms used in the PCB industry, you may be wondering: What is HDI PCB stackup? Here are some of the most common definitions:
High-density insulated (HDI) PCBs are multilayer printed circuit boards. Each layer is made of a different material. A build-up HDI has sequential layers, while an any-layer HDI uses an every-layer interconnect. Sequential laminations are usually composed of copper-filled micro via structures and involve a core construction. High-pin-count devices often use any-layer HDI PCBs. The cost of an overall board is determined by the number of laminations.
A high-density HDI PCB has a track layout with a high-density configuration. It first emerged in the 1990s and quickly became a popular type of PCB. The technology behind HDI PCBs is advanced and is a common feature of smartphones and tablets. Wi-Fi modules and Bluetooth devices are other high-end PCBs that use HDI technology. Developed by IBM in 1989, the technology has become a common component in smartphones and tablets.
Just have a look at this video:
HDI PCBs use buried, micro vias, and blind vias. These types of vias can be staggered and are ideal for dense multilayer PCBs. Because of their thin-dielectric nature, HDI PCBs are often more expensive to manufacture. If you’re wondering: what is HDI PCB stackup?, let’s examine some examples of the different types of HDI PCBs.
What exactly is the HDI PCB layout? This design has numerous advantages. For starters, it is more efficient. A conventional PCB has fewer components per inch. Furthermore, HDI’s reduced footprint makes it easier to handle and more adaptable.
HDI layouts are often simple to utilize, so there’s no need to be intimidated. Here are some pointers to help you with HDI PCB designs.
The technique of constructing circuit boards with fine pitch components and higher component density is known as high-density integration (HDI). High-density traces are made using the same procedures as standard PCBs, but with greater attention to detail.
The cost is also affected by the number of layers and stackup height. Furthermore, to avoid oxidation, HDI PCBs may necessitate laser drilling of vias.
HDI type II permits buried vias or blind holes but require at least one through-hole. Type III necessitates buried vias but is not a coreless structure. It also supports PTH holes and ground planes. It’s vital to realize that the more holes a PCB require, the more expensive it is. When selecting an HDI PCB layout, speak with your engineer or designer to ensure the layout is appropriate for your needs.
What exactly is the HDI PCB layout? HDI circuit boards are typically four layers thick, and the manufacturing process is identical to that of traditional PCBs. The sequential drilling of buried holes in each layer is required for this design approach.
In addition, HDI necessitates a mechanical through-hole and a single-blind hole in each layer. These holes can be formed by HDI PCB manufacturers using laser technology. They can be constructed with as few as two holes or as many as four layers.
There’s one video:
You may be wondering, “What is HDI PCB manufacturing?” when looking for a company to create your next printed circuit board. After all, there are numerous steps involved in the development of this type of board.
But which method is best for you? And what can you anticipate? The most prevalent HDI PCB manufacturing procedures are discussed here. You could be pleasantly surprised by what you discover.
The fabrication of an HDI PCB begins with the lamination of the circuit boards. The successive application of copper and pre-preg layers is involved in this technique. Heat and pressure are required throughout the lamination process, and HDI boards go through many lamination steps. This prevents the boards from moving while drilling.
AOI for HDI PCB
The more layers there are on a PCB, the more expensive it is. As a result, HDI PCB manufacturers will provide you with higher quality, reduced costs, and shorter turnaround times.
The HDI method employs a 2-n-2 arrangement, which is more complicated than 2-n-stacking. Because the final HDI PCB design is more complex than typical PCBs, it is critical that the design team knows the device and layout requirements before the manufacturing process begins.
The main difference of manufacturing between HDI board and standard PCB are the laser drilling and plugging with resin. Others are almost the same.
You’ve come to the right site if you’re seeking the greatest HDI PCB. Micro vias, via-in-pad technology, and adaptable routing are used on this type of PCB to deliver optimal performance and save costs. Because the board employs via-in-pad technology, all functionalities may be crammed into a single board, decreasing the number of components.
This sort of PCB is also exceptionally dependable, with stacked vias giving an extra layer of protection against harsh environments. It also has laser drilling, which makes smaller holes and enhances the board’s thermal qualities.
The cost of HDI PCBs might vary, and designers must consider their demands while selecting a layout. The final price is affected by the number of layers as well as the number of them.
Types of HDI PCB
The more layers you select, the more expensive the HDI PCB. A 2+N+2 layout is more expensive than a 1+N+1 layout, and adding layers considerably increases the cost. As a result, regardless of the complexity of your product, it is critical to select a layer count that is ideal for your purposes.
HDI PCBs serve two key functions: cost reduction and component reduction. Thinner lines and a tighter circular ring characterize a conventional HDI PCB. The laminated and mechanically drilled cores are available for the HDI Stackup. Creating a high-quality HDI PCB, the latter requires laser drilling. For smaller boards, however, an HDI PCB is not required.
When it comes to HDI PCB fabrication, you must select a manufacturer who will give you high-quality items. International certification is the first item to search for.
Because PCB products are primarily exported to other nations, the manufacturer must have all of the appropriate certifications. If a production company is registered, its inspection certificates will be displayed on its website.
To maintain precision and accuracy, HDI PCB production necessitates the use of specialized procedures and equipment. For HDI vias, for example, a laser is necessary and can only drill so far.
Multiple drilling operations or consecutive layer boding may be required for HDI boards. This might add time and money to the production process. As a result, it is critical to select a manufacturer that is capable of handling delicate details.
Make sure to conduct your research before purchasing HDI PCBs from China. You want to avoid scams and low-quality products, so buy from trusted companies.
They may be a little more expensive, but they will be worth it in the long term. Look for high-quality, safe products that are delivered on time. Then, double-check the price. Consider how much you’re willing to spend on your project before deciding on an HDI PCB maker.
How many layers will be required? The more layers there are, the greater the price.
HDI PCBs are often made up of many layers. The number of layers will be determined by the design’s intricacy and the overall performance of your product. A larger layer count may result in improved performance, but it also increases expenses and processing time.
