Political and supply-chain issues could not slow printed circuit growth in 2021.

 The author attended his first IPC meeting in 1966. At that time, the consensus was the world PCB output was $500 million. Some “knowledgeable” experts predicted PCB output would dwindle since semiconductors were rising rapidly and PCBs would not be needed. If that $500 million assessment was correct, in 55 years the PCB market grew 192 times, to $96 billion!

It is with that in mind that the author embarks on another attempt to establish the value of the world’s printed circuit board market, culminating in the NTI-100 list of the largest fabricators.

In fact, the author thought he would cease the NTI-100 report a few years ago. However, his curiosity about the world PCB industry (2022 is his 57th year in this industry) remains a motivator, and once again he made the NTI-100 list. Every year he wants to quit, but does not want to disappoint the industry. So, he may continue to compile the NTI-100 data so long as his brain has the capacity to be patient and functional.

When the author first compiled what is now known as the NTI-100 list, “100” implied the top 100 fabricators. Around 2005, he realized the top 100 fabricators did not cover the full scale of world PCB production. He decided to change 100 from “100 top fabricators” to “fabricators with revenue of $100 million or greater.” Hence, “100” of NTI-100 means “$100 million.”

Exchange Rates

We begin this report with the exchange rates of major currencies against the US dollar. As in the past, exchange rates are calculated using This website describes daily exchange rates of various currencies during weekdays (265 days). The author added the exchange rate of each of 265 days, summed, and divided the sum by 265 to arrive at the exchange rates shown in TABLE 1.

Table 1. Average Exchange Rates: Local Currency/USD

8 nakahara table 1

Most of the currency fluctuations have been relatively small. But since around March, the value of the yen started to decline rapidly against the US dollar. As of this writing, it is traded at about ¥136/$1. If this rate is persistent, Japanese fabricators’ ranking will be pushed down considerably in NTI-100 2022 edition. We shall see. Every year, there must be errors, which are the sole responsibility of this author. The rankings are reasonably accurate, hopefully. Please view them merely as reference.

Data Collection
Data are collected from annual reports for stock-listed fabricators. For privately owned companies, data compiled by TPCA and CPCA are used. For many others, the author’s industry friends helped. Using this opportunity, he would like to express his gratitude to those organizations and individuals for their able assistance.

A big challenge was to convert English names to local names and vice versa. Here, his knowledge of Chinese characters helped. Chinese companies have many names. To be clear, internationally recognized or recognizable names are used for English.

Simple comments are included in the last column of the table for those fabricators the author is familiar with. For many Chinese fabricators, their websites are substituted for comments because the author is not intimately familiar with them. For room, some descriptions are shortened. For example, IC PKG Sub stands for IC package substrate, which Taiwan and China call a “carrier board.” Likewise, Auto PCB refers to automotive PCB, and so on.

Simple Analysis

Of the 146 fabricators in the 2021 NTI-100, the author is personally quite familiar with about half. He visited their factories many times, and they are also well publicized. Brief comments are included to highlight their status. They are mostly publicly traded, and detailed information can be extracted from their websites.

The 2021 world PCB production value was $96 billion, which is the best estimate by this author. The value is derived from the NTI-100 list and from unranked companies. That sum includes about $9 billion of estimated assembly value, mainly made by flex circuit fabricators. But, in recent years, rigid board makers are also moving into this business arena. Of some 600+ Chinese makers this author investigated, about half are engaged in assembly and claiming a “one-stop-shop.” In many cases, their assembly business is larger than the bare board business. But most are small- to medium-sized companies and are not in the NTI-100. What the author is driving at is that it is impossible to accurately separate the assembly business from the total PCB output (bare board plus assembly). The bare board value was an estimated $87 billion in 2021.

IC package substrates. Looking at growth companies, those with the highest growth in 2021 were IC package substrate specialists. Seven fabricators have IC package substrate revenue greater than $1 billion: Unimicron ($2.08 billion), Ibiden ($1.96 billion), SEMCO ($1.53 billion), Shinko ($1.39 billion), LG Innotek ($1.27 billion), Nanya PCB ($1.23 billion) and Kinsus ($1.09 billion). The author’s estimate of worldwide IC package substrate production in 2021 was $15.6 billion, or 17.9% of the total bare board production of $87 billion. From 2019 to 2025, IC package substrate makers have committed more than $25 billion to expand existing plants or build new ones, mostly the latter. AT&S’ Malaysia plant will cost $2.2 billion. Ibiden will spend about $4.5 billion during this period. (Investment information is publicly available.) In the PCB industry, ROI is said to be 1:1. So, one can imagine what that $25 billion (all earmarked for Asia Pacific) will do in terms of IC package substrate production value when all those plants go into full production.

Automotive PCBs. Despite the component shortage, automotive production rose modestly in 2021 to 83 million units, from 78 million in 2020. Electric vehicle (EV) unit sales rose to 6.5 million units, up 3.5 million units year-over-year. The increase in EVs, which use three times as many PCBs as conventional internal combustion engine cars, coupled with the higher selling prices due to copper-clad laminate price increases, boosted automotive PCB production to $9.3 billion in 2021 from $7.8 billion in 2020. Automotive’s share of bare board sales in 2021 was 10.8%. Automotive PCB fabricators benefited from these developments. Major automotive PCB makers in 2021 were Meiko ($672 million), CMK ($665 million), Nippon Mektron ($640 million), Chin Poon ($560 million), TTM Technologies ($511 million), Unimicron ($440 million), Kingboard ($420 million), Tripod ($408 million), KCE ($350 million), and Dynamic ($296 million).

In early 2000, the flex printed circuit (FPC) share of total PCB sales was only 4%. In 2021, the total FPC output was $18 billion, of which $13 billion was bare board. Hence, the FPC bare board share was 14.9%. Many top fabricators are FPC makers, such as Zhen Ding, DSBJ, Nippon Mektron, Kinwong, Young Poong Group, etc.

Computing. Fabricators of motherboards for smartphones, PCs and tablets did well because of demand for these products for work and school. As students returned to classrooms and enough PCs were made and distributed, however, motherboard demand for these products seems to be slowing.

Entries by Country

TABLE 2 shows the geographic distribution of the NTI-100. Total world PCB production was $96 billion. Of that, $57 billion was produced in China by Chinese nationals and foreign transplants. Broken down further, domestic Chinese fabricators accounted for 60%, or $34 billion, of the $57 billion, Taiwan transplants 29% ($17 billion) and the rest, $6 billion (11%), was made by AT&S, TTM, and Japanese and Southeast Asia transplants. Taiwan once had 35% of the PCB production in China. Although the Taiwanese production in China is growing, growth by Chinese fabricators is outpacing that of their Taiwanese competitors in China. Therefore, the gap between Taiwan and Chinese makers will widen.

Table 2. NTI-100 Ranking by Region

8 nakahara table 2

Looking at Table 2, if the revenue of the top Taiwan and Chinese fabricators is added (28,873+27,634), the sum is $56.51 billion, or 64% of the world output (56,507/87,765). Taiwan’s total PCB output by fabricators from Taiwan, China and Thailand was $29.3 billion in 2021.

If Taiwan’s and China’s total outputs are added, the sum is $63.3 billion. That is, Taiwan’s and China’s “total output” is 66% (63.3/96) of the world production. This ratio is very close to the total share (64%) of the Taiwan and China fabricators on the NTI-100 list. With 100 or more new PCB projects pending over the next several years in China, many on a grand scale (if realized), China’s and Taiwan’s share of global production will exceed 70%.

Twenty-five fabricators achieved revenue greater than $1 billion in 2021, with 10 topping $2 billion (TABLE 3). In 2002, no company exceeded $1 billion. The top fabricator that year was Ibiden, with $932 million in revenue. A decade ago, in 2012, 13 fabricators had revenue exceeding $1 billion, of which four topped $2 billion.

8 nakahara table 3d

While the 146 companies on this year’s NTI-100 represent only 6% of the estimated 2,400 fabricators in the world, they produced 92% of the output. As we say, the big get bigger every year. Without investment, growth will be limited. There are some unrealistic remarks made that PCB will be replaced by just chips. What do you think? PCB output will continue to increase, at least in the lifetime of this author.

Due to the US-China trade and political tension and supply-chain disruptions in China caused by frequent and prolonged lockdowns, some fabricators are reluctant to put all their proverbial eggs in one basket (China). Work has begun on PCB plants in Malaysia, Thailand and Vietnam. PCB production in 2021 in these Southeast Asian countries, plus production in Singapore and the Philippines, was $7.8 billion. Soon production will exceed $10 billion annually. The rate of growth in China will be larger, however.
