Introduction to the difference between HDI board and ordinary PCB

HDI board (High Density Interconnector), that is, high-density interconnect board, is a circuit board with a relatively high line distribution density using micro-blind buried hole technology. HDI board has inner and outer layers, and then uses drilling, in-hole metallization and other processes to connect the internal layers of each layer.

HDI board is generally manufactured by lamination. The more times of lamination, the higher the technical level of the board. Ordinary HDI board is basically 1-time lamination, and high-end HDI uses 2 or more times of lamination technology, and also uses advanced PCB technologies such as stacking holes, electroplating filling holes, and laser direct drilling.

When the density of PCB increases to more than eight layers, the cost of manufacturing with HDI will be lower than the traditional complex pressing process. HDI board is conducive to the use of advanced assembly technology, and its electrical performance and signal accuracy are higher than traditional PCB. In addition, HDI boards have better improvements in radio frequency interference, electromagnetic wave interference, electrostatic discharge, heat conduction, etc.

Electronic products are constantly developing towards high density and high precision. The so-called "high" not only improves the performance of the machine, but also reduces the size of the machine. High-density integration (HDI) technology can make the terminal product design more miniaturized while meeting higher standards of electronic performance and efficiency. Currently, many popular electronic products, such as mobile phones, digital (cameras), laptops, automotive electronics, etc., use HDI boards. With the upgrading of electronic products and market demand, the development of HDI boards will be very rapid.

Introduction to ordinary PCB

PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Because it is made using electronic printing technology, it is called a "printed" circuit board.

Its main function is to avoid manual wiring errors due to the consistency of similar printed boards after electronic equipment adopts printed boards, and can realize automatic insertion or mounting, automatic soldering, and automatic detection of electronic components, ensuring the quality of electronic equipment, improving labor productivity, reducing costs, and facilitating maintenance.

HDI board is a high-density interconnection circuit board. The boards that are electroplated with blind holes and then pressed again are all HDI boards, which are divided into first-order, second-order, third-order, fourth-order, and fifth-order HDI. For example, the motherboard of iPhone 6 is a fifth-order HDI.

Simple buried holes are not necessarily HDI.

How to distinguish between first-order, second-order, and third-order HDI PCBs

The first-order is relatively simple, and the process and technology are easy to control.

The second-order is troublesome. One is the alignment problem, and the other is the problem of punching and copper plating. There are many designs for the second order. One is that the positions of each order are staggered. When the adjacent layer needs to be connected, it is connected through wires in the middle layer. The method is equivalent to two first-order HDIs.

The second is that two first-order holes overlap and achieve the second order by superposition. The processing is similar to two first-order holes, but there are many process points that need to be specially controlled, which is what is mentioned above.

The third is to drill directly from the outer layer to the third layer (or N-2 layer). The process is very different from the previous one, and the difficulty of drilling is also greater.

For the third order, the second order is analogous.

Ordinary PCB boards are mainly FR-4, which is made of epoxy resin and electronic grade glass cloth. Generally, traditional HDI uses adhesive copper foil on the outermost surface. Because laser drilling cannot penetrate glass cloth, adhesive copper foil without glass fiber is generally used, but the current high-energy laser drilling machine can already penetrate 1180 glass cloth. In this way, there is no difference from ordinary materials.

Hexamethylene Diisocyanate (HDI) Prices | Pricing | Trend | News | Database | Chart | Forecast

 Hexamethylene diisocyanate (HDI) prices is a chemical compound widely used in the production of polyurethanes, coatings, and adhesives. HDI plays a crucial role in numerous industries, particularly in automotive, aerospace, and industrial applications, due to its ability to create highly durable and resistant coatings. In recent years, the price of HDI has been subject to various fluctuations influenced by multiple factors such as raw material availability, production costs, demand trends, and global economic conditions. Understanding the dynamics of HDI prices is essential for manufacturers and businesses reliant on this chemical, as shifts in pricing can significantly affect production costs and profitability.

The primary driver of HDI prices is the cost of raw materials. HDI is synthesized from hexamethylene diamine (HMD), which itself is derived from petrochemical feedstocks. As a result, any fluctuations in crude oil prices and the availability of petrochemical derivatives can impact the cost of HDI production. Crude oil prices are volatile, being influenced by geopolitical tensions, OPEC production decisions, and natural disasters that disrupt supply chains. As crude oil prices increase, the cost of producing HDI tends to rise, leading to higher market prices for this chemical. On the other hand, when crude oil prices decline, HDI producers may experience lower production costs, potentially leading to a decrease in HDI prices if demand remains stable.

Environmental regulations and sustainability trends also affect HDI prices. As the world increasingly focuses on reducing carbon emissions and promoting sustainable practices, manufacturers of chemicals like HDI are facing stricter environmental regulations. Compliance with these regulations often requires costly investments in cleaner technologies, waste management, and emissions control systems. These additional costs are typically passed on to consumers, contributing to higher HDI prices. Moreover, some manufacturers are seeking to develop bio-based alternatives to petrochemical-derived HDI, which could lead to shifts in pricing as the market adjusts to new technologies and production processes.

The global demand for HDI is another critical factor influencing its price. HDI is in high demand in sectors such as automotive, construction, and aerospace, where it is used to produce high-performance coatings that offer protection against corrosion, weathering, and chemical exposure. As these industries experience growth, the demand for HDI increases, putting upward pressure on prices. For example, the automotive industry has seen a surge in demand for electric vehicles (EVs), which require specialized coatings to protect battery components and other sensitive parts from environmental degradation. This increased demand for HDI in the EV market has contributed to higher prices, as manufacturers seek to secure sufficient supplies of this essential chemical.

Another factor to consider when analyzing HDI prices is the level of competition among manufacturers. The global HDI market is highly competitive, with key players including major chemical companies based in North America, Europe, and Asia. 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.

What is a Flex PCB?

Flex PCB boards or flexible printed circuit boards, as the name suggests, carry out the function of regular PCB boards while being physically flexible. As you must know, PCBs or printed circuit boards carry out the function of establishing connections among various components inside an electrical or electronic device. While rigid PCB boards have ruled the market for so many years now, flex PCB boards emerged and opened the door to new possibilities due to their dynamic nature.

Bare boards of flexible printed circuit boards are made of flexible materials allowing them to bend and be manipulated as per the designer’s requirements. This feature of bendability and flexibility comes in handy while crafting various new-age gadgets such as wearables. To know more about these circuit boards also known as flexible circuit boards, continue reading below.

Classifications of Flexible Printed Circuit Boards

Flex PCB manufacturers can now design, fabricate, and customize PCBs with a wide variety of specifications. While the variations are enormous, flexible circuit boards can broadly be classified into a few types based on their layers and configurations.

By Layers: Single-sided, Double-sided, and Multi-layer flex PCBs

Based on the number of layers present in a flexible printed circuit board, they can be classified into single-sided, double-sided, and multi-layered PCBs. Each type has its advantages and features. While a higher number of layers allows a connection of more components, the complications, and overall costs also increase along with. Therefore, engineers at Hitechpcba study the project requirements carefully to find the best-suited type of flexible printed circuit board for an application.

Single-sided flex PCBs: Single only only have one conductive layer. These are the most commonly used flexible printed circuit boards, with excellent electronic and mechanical properties of flexible material, and also low cost. So they are widely used in consumer electronics.

What is an HDI PCB board?

HDI PCB boards are thin, light and compact, and can achieve high-density interconnection of PCB boards.

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%.
