According to Dinner Party Economics, the Human Development Index (HDI) is defined to be a tool to help governments measure several quality of life aspects of a country. This includes life expectancy, education and income.[1] Canada’s current HDI Index was 0.937 in 2022, which is considered to be a good score.[2] However, a study done by Indigenous Service Canada found that across the board, Indigenous peoples score a lower HDI number compared to other Canadians. The most recent and lowest score belongs to Indigenous peoples who live on reserves, with a score 0.69.[3] This score is to be expected as reserve communities are faced with the water crisis the hardest. However, this score can be improved and lead to economic growth. A study done by Harvard University found that the economy is does better when the health of its citizens is at their best.[4] Improving the HDI score for Indigenous folk can drastically affect the Canadian economy in a beneficial way.

The labour force participation rate is the rate of the population who are currently employed by an organization.[1] Overall, the labour force participation rate of Indigenous peoples is lower than those who aren’t of Indigenous descent.[2] Ted Wannell and Sheila Currie did some preliminary research and found that there was a correlation between the infrastructure of water treatment systems and the employment of the Indigenous peoples in that communities.[1] While there is more research that needs to be done, this idea is not an unfounded one. Many Indigenous travel far distances to get fresh and drinkable water, as is the case with Ashley Sakanee.[2] The time spent getting water can be used to looking and working a job. Improving the water quality can increase the labour force participation rate of Indigenous peoples.

To put simply, the multiplier effect is the proportional amount of spending (or lack thereof) that an organization does that causes other organizations to spend as well. This can be beneficial to restart the economy during a recession period. Since one company is spending money, another company may also spend to keep up, giving the economy a boost.[1] The government is clearly willing to spend money into this cause, as stated by their federal budget.[2] The government money used in this solution will be given to manufacturing companies to the spending more to build water treatment facilities. This extra spending done by the government and these companies can kickstart the economy further to recover from the downturn brought by the pandemic.

Yes but they industrialized, there were higher literacy rates, rural poverty decreased, the economy grew, the HDI skyrocketed, and for more people things improved

I grew up in what is now a former SSR

I know the USSR is bad, but saying it wasn’t an improvement from the feudal, backwards, colonial tsarist empire is FUCKING IDIOTIC

I hate Stalin, but writing off the entire USSR as being worse than tsarist Russia is absurd and strips you of all credibility

And again, human rights in the USSR sucked, but you know what was worse? Human rights in Tsarist Russia

A little advice from someone studying extremist groups: if you’re in a social media environment where the daily ubiquitous message is that you have no hope of any kind of future and you can’t possibly achieve anything without a violent overthrow of society, you’re being radicalized, and not in the good way.

These companies continually seek to optimize production processes, improve efficiencies, and develop new applications for HDI to gain a competitive edge. Increased competition can sometimes lead to price reductions as manufacturers attempt to capture market share by offering lower prices. However, in times of tight supply or high demand, these same companies may raise prices to maximize profits. The level of competition in the HDI market can, therefore, play a crucial role in determining price trends over time.

International trade policies and tariffs also have an impact on HDI prices. Trade tensions between major economies, such as the United States and China, have led to the imposition of tariffs on various chemical products, including HDI. These tariffs increase the cost of importing HDI, which can lead to higher prices for domestic consumers. In some cases, manufacturers may seek to shift production to regions with more favorable trade policies or invest in local production to avoid tariffs. Changes in trade agreements or the introduction of new tariffs can create price volatility in the HDI market, as businesses adjust to new regulatory environments.

Finally, the development of new technologies and innovations in HDI production could influence future price trends. Advances in chemical engineering, process optimization, and automation have the potential to reduce production costs, making HDI more affordable for manufacturers. Additionally, research into alternative raw materials, such as bio-based or recycled feedstocks, could lead to more sustainable and cost-effective production methods. As these technologies become more widely adopted, the cost structure of HDI production may shift, potentially leading to lower prices in the long term.

In conclusion, the price of hexamethylene diisocyanate (HDI) is influenced by a complex interplay of factors, including raw material costs, supply chain dynamics, environmental regulations, global demand, competition, trade policies, and technological advancements. As industries continue to evolve and adapt to changing market conditions, understanding the key drivers of HDI pricing will be essential for businesses that rely on this chemical to optimize their operations and remain competitive in a rapidly shifting economic landscape.

HDI PCB stands for high-density interconnection PCB. HDI board is the name that Japanese companies have always given to high-density interconnection printed circuit boards, while in Europe and the United States, HDI boards are called "micro-perforated boards". HDI is a PCB technology. It is a method of making high-precision circuit boards that has developed with the development of electronic technology. It can achieve high-density wiring and is generally manufactured by stacking. HDI uses conventional multi-layer boards as the core board, and then stacks insulation and circuit layers (also known as "stacked layers") layer by layer, and uses laser drilling technology for layer drilling, so that the entire printed circuit board forms a layer connection with buried holes and blind holes as the main conduction method.

Compared with PCB, HDI PCB has higher production process requirements:

According to the actual difficulty, market size and development trend of basic HDI PCB manufacturing, HDI can be divided into the following three categories:

(1) Entry level: first order (1+C+1), second order (2+C+2), third order (3+C+3)

(2) General class: any layer (n+C+n, mostly 10-12 layers).

(3) High-end class: SLP, rigid flexible PCB board (rigid board area using HDI technology)

The advantages of HDI PCB are light, thin, short and small, which can increase circuit density, facilitate the use of advanced packaging technology, greatly improve signal output quality, greatly improve the function and performance of electronic and electrical products, and make electronic products more compact and convenient in appearance. For high-end communication products, HDI PCB technology helps to improve signal integrity, facilitate strict impedance control, and improve product performance.

According to Prismark's report, the output of HDI in 2018 was US$9.222 billion. Affected by the weak downstream mobile phone market, the output value in 2017 increased by only 2.8% year-on-year, while the total output value of the PCB market increased by 6.0% year-on-year. From 2018 to 2023, the annual growth rate of HDI output is expected to remain at around 2.9%.

HDI PCB design guidelines

in Circuit Board Fabrication, high density interconnect pcb

sales12@hitechpcb.com

High density interconnect boards, popularly known as HDI PCBs are becoming more popular in the electronics industry. These boards offer high performance and are specially designed for some specific applications. Modern devices are becoming more compact and also the components in these devices are becoming smaller. The invention of the HDI circuit board has contributed to this development.

What is HDI PCB?

High density interconnect (HDI) PCB is type of circuit board with higher wiring density for each unit surface area. This density is more than that of a standard board. Also, HDI boards have finer lines and space. They comprise minor vias which can capture pads.

HDI board integrates minimum layers and thin materials for its composition. Therefore, these help to enhance its efficiency and performance. HDI PCB layout is suitable for complex designs. Also, HDI boards offer a lot advantages. These boards enhance electrical performance and reduce the size and weight of equipment.

The vias in HDI PCBs are equal to or less than 150 micrometers. Also, the spaces and lines in these boards are equal to or less than 100 micrometers. All these contribute to the reduced size of HDI boards. Furthermore, the increased interconnection density of HDI PCBs helps to improve signal strength and as well increase reliability. HDI PCBs integrate ultra thin materials and very minimum layers compared to standard PCBs.

HDI PCBs contributed to the development of more powerful and smaller electronic devices. When the lines on a circuit become much smaller than 65 microns, therefore, the possibility to etch your space and trace reduces.  For instance, etching on a standard PCB enables a thick resist and there are much spaces for tolerances to etch those spaces.

Definition of HDI circuit boards

In the IPC-6012 it is considered an HDI PCB when the electrical connections on average reach a number of 20 connections per cm2, on both sides of the core and generally to reach these conditions, microvia tracks and gaps should not exceed 100 um. If we think that the parameters described are developed on all layers of the circuit, we understand that it poses great technological challenges for PCB suppliers.

Fig 1 Here we show you the current situation that Hitechpcba can support, type III structures based on a central nucleus called NB + 3 sequences of blind holes, NB +4 and +5 sequences will soon be available Including the ELIC structure up to 10L (ELIC = EVERY LAYERS INTERCONNECT)

HDI PCBs are usually classified by the HDI builds, and there are the 1+N+1, 2+N+2, 3+N+3, 4+N+4, and ELIC HDI PCB( Every Layers Interconnect HDI PCB). In the HDI PCB’s outer layers, microvias usually form the more expensive stacked vias or cheaper staggered vias.

HDI PCB has a Symmetrical Structure: Inner and Outer Circuit Layers

HDI PCB Builds: 1+N+1, 2+N+2, 3+N+3, 4+N+4, 5+N+5 and ELIC HDI PCB

HDI builds means how many times of laser drilling for microvias. 1+N+1 is the simplest HDI build, and it means the HDI PCB’s microvias are single vias that need only one laser drilling.

3+N+3 means the HDI PCBs need three times of laser drilling and both the upper and bottom outer layers have 3 PCB layers. And so on. The more times of laser drilling, the higher requirements for HDI PCB manufacturing technologies and more costs. 1+N+1, 2+N+2, 3+N+3, and 4+N+4 HDI PCBs are used commonly. 5+N+5 HDI PCBs are also in use but less. For example, iPhone 6 uses the 5+N+5 HDI PCB as its mainboard.

ELIC HDI PCB means Every Layers Interconnect PCB

Are you designing high-density interconnect PCBs?

HDI PCBs are characterized by their high density of components and routing interconnections, using the latest design and manufacturing technologies.

An HDI PCB is a high-performance board that takes advantage of

Laser microvias

Blind and buried vias

Fine lines and spaces

Via-in-pad technology

Built-up and sequential PCB laminations

Fine pitch devices down to 200 microns

And HDI PCB design is a critical process that necessitates expertise, experience, and the proper utilization of technology. In order to aid in your understanding of HDI layout and facilitate successful HDI PCB design, we are sharing some key considerations and suggestions to keep in mind during the design process in this blog, with the hope of inspiring you to create innovative HDI designs.

HDI PCB design is a specialized approach that optimizes component placement on a printed circuit board (PCB) to maximize space utilization and minimize signal interference. It is particularly beneficial for designing compact and high-performance electronic devices like smartphones, tablets, and wearables.

There are various types of HDI layouts, including the sequential build-up, stacked vias, and microvias. In the sequential build-up, layers of the PCB are built up sequentially to achieve the desired density. Stacked vias involve drilling holes through multiple layers of the board to create interconnections. On the other hand, microvias are similar to stacked vias, but they are much smaller in size, allowing for even higher component density on the PCB.

Why is HDI PCB Important in Electronic Manufacturing?

There are various benefits of HDI technology. First of all HDI technology helps to reduce the size of devices due to the high connection pad density. Also, HDI PCBs enhance performances of devices. HDI technology contributes to the manufacturing of wearable electronics, handheld electronic devices, and smartphones. Furthermore, the ability to integrate more components in electronics makes HDI PCBs are preferred option among manufacturers.

Smaller weight and size

HDI PCBs enable the production of smaller devices. This is because these boards allow the integration of more components. With reduced board size, manufacturers can build devices that can fit into smaller spaces.

Enhanced signal transmission

High density PCB enhances signal transmission. Also, these boards improve signal quality in electronic devices.

Denser trace routing

HDI PCBs enable manufacturers to integrate more components on the circuit board. This enables denser trace routing. Also, HDI PCB design offers more freedom to freedom to integrate more components on both sides of the board.

High reliability

HDI PCBs are very reliable as a result of its integration of stacked vias. Also, HDI boards offer great protection against any extreme environmental conditions.

Cost effective

HDI technology offers cost effective solutions for electronics production. Quality is a crucial factor when designing electronics. HDI design makes it possible to minimize a standard 8 layer PCB to a 4 layer HDI PCB through the use of microvia. Also, a well-designed 4 layer HDI PCB can offer better functions more than an 8 layer standard PCB.

HDI PCB Design Considerations

Use of microvias

The use of microvias can help PCB designers to achieve more number of pins. Also, microvias can create the escape area of dense components. Microvias feature low inductance which makes them ideal for high-speed applications. Also, they help to link power planes with decoupling capacitors.

Component selection

An HDI PCB usually comprises SMD and BGA components. Also, it is crucial to choose the pitch/spacing between these pins. Proper spacing between pins helps to define board stack-up and trace widths.

Material selection

This is an important consideration for every PCB design. However, it is a more crucial consideration in HDI PCB design. Selecting the appropriate material is ideal for manufacturability and also meeting electrical requirements.

Thermal management

The IPC-2226 standard points out thermal issues in circuit board. Therefore, it is advisable to refer to this standard to ensure better thermal management. Also, designer needs to prevent these thermal issues. Thinner dielectrics can ensure thermal dissipation. It is advisable you add thermal vias to increase dissipation.

Testing

Rather than using In-circuit testing, HDI PCB designers integrate JTAG or functional testing. This is because in-circuit testing usually requires full nodal analysis.

Vias capping

It is advisable you cap or fill microvias to offer a planar surface. Also, capping of vias enables designers to place active parts on the two sides of the PCB. Failure to cap your vias can cause air bubbles and this will affect the quality of solder joint.

Minimized plane perforation

Bigger ground or power copper are enhances power integrity and electromagnetic compatibility. However, microvias create a small gap wherever they perforate a plane and this can have effects on power integrity, signal integrity, and electromagnetic compatibility. Therefore, perforate less to get higher shielding and better image plane effect.

The Trends and Future of HDI PCB Technology

In life, humans will always demand for changes. Change is a constant thing in life. Constant change, innovation, and development keep happening in the electronics industry. The advent of HDI PCB technology has led to development in electronics manufacturing. Almost all industries benefit from HDI printed circuit board technology.

In the past, printed circuit boards comprise several conductive layers. Things have changed as this is no longer the case. For HDI board technology, the future seems bright.  More complex and compact devices will be manufactured. The capability of HDI boards to integrate more components on both sides will make this possible.

Furthermore, blind via and via-in-pad technologies will aid this development. Devices that will be primarily manufactured with HDI circuit boards will transfer signals faster and reduce signal loss. Also, the integration of laser drilling in HDI circuit boards enhances their capabilities. HDI printed circuit boards have fine pitch components.

HDI printed circuit boards minimize the number of conductive layers for a circuit board, thereby reducing dense trace routing. Also, HDI PCBs integrate microvias, buried, and blind vias which enhances routing within a small space. Due to this capability, there is minimized distributing inductance. Hence, this enhances signal integrity.

Also, the HDI PCB technology enabled alternative stack up techniques due to the integration of buried vias, blind vias, and microvias. The integration of drilled sequential lamination has helped manufacturers to increase the density of boards.

Crucial Things to Understand in HDI PCB

Microvia Hole

A microvia hole is a blind hole created on the conductor-insulator multilayer. It creates electrical connection via an insulator in the conductive layers.

Minimum pad size hole

The minimum pad size hole on the internal or external layer of an HDI PCB should be +0.010. However, the pad size hole should be +0.014 for the component holes.

Copper wrap

Copper wrap refers to the copper layer that shields the filled holes’ outer surface. Also, the copper wrap’s thickness depends on the outer surface copper thickness of the plated hole.

Recommended via hole plugging

The hole plugging resin always fill the via holes. A permanent hole filling substance will fill this hole.

Capped via hole

The surface’s flatness determines the via in pad design. Also, the holes will be filled with resin. Therefore, you will need an additional thin copper cap.
