The growth in demand for AI servers has driven upstream PCB materials such as fiberglass cloth and copper foil to be in short supply and prices continue to rise. The industry is looking for new materials such as PTFE as alternatives.
[Reporter Zhuo Yijun/Special Report] The rise of the AI wave is reshaping the new value of PCB, the "mother of industry". Upstream materials such as fiberglass cloth, copper foil, copper foil substrate, and drill pins have been in short supply since last year, triggering a wave of price increases. With the next generation of AI With the launch of servers, the supply gap continues to expand, and new alternative materials have also become the target of market pursuit. PTFE (polytetrafluoroethylene) is considered to be expected to replace fiberglass cloth and quartz cloth. Taihong (8039) and Taijun (6269) are included in Nvidia’s list. The PTFE partner of NVLink PTFE switch board (switcher), Yadian (4939) also develops high-end PTFE materials. Taihong, Taijun, and Yadian bucked the trend last week and rose against the trend, with their stock prices rising by 1.96%, 28.9%, and 6.39% respectively.
According to statistics from TPCA (Taiwan Circuit Board Association), the domestic and overseas output value of Taiwan PCB material manufacturers in the first half of the year reached NT$271.6 billion, an annual increase of 38.6%. The growth mainly comes from high-frequency and high-speed CCL (copper foil substrate) in hard board materials. In addition, key materials such as fiberglass cloth and copper foil continue to be in short supply.
Affected by tight production capacity and rising raw material costs, material prices have gradually increased, further pushing up the overall PCB materials industry output value; upstream material shortages are caused by Low CTE, Low High-end materials such as Dk2 and HVLP4 are gradually expanding to include CCL, high-end PCBs, ABF carrier boards, process equipment and consumables. Even if manufacturers are actively expanding production, AI demand is strong, and customer certification and yield improvement will take time. New supply will still be difficult to completely fill the gap in the short term. It is estimated that the tight supply chain will continue until at least 2027.
Taihong's PTFE material has been included in Huida's supply chain, which means that PTFE has become Huida's new generation PCB material. It has the opportunity to replace fiberglass cloth or quartz cloth and solve the problem of limited upstream material production capacity. Currently, Taihong's PTFE is undergoing customer verification and sample delivery, and will be introduced into mass production in 2027 at the earliest.
Taijun has continued to promote transformation in the past three years, including the integration of new materials upstream. Materials ranging from Modified PI (modified polyimide), LCP (liquid crystal polymer) to PTFE have been invested in research and development, and customized designs are carried out according to customer needs. Currently, it has participated in the next-generation platform development project of AI server major customers. The relevant new material solutions continue to be tested and certified, and are expected to enter the next-generation new platform.
AsiaDian's high-end PTFE materials are being verified through upstream and downstream supply chain partners. If customer certification is successfully completed and mass production is introduced, it is expected to make a significant contribution to revenue.

Taiwan stocks plummeted last Thursday, with foreign investors selling more than 302.5 billion yuan in a single day, hitting a record high. However, financial stocks bucked the trend and strengthened. The financial index closed at 3,750.52 points last Friday, a record high, with a cumulative increase of 56.64% this year. Analysts pointed out that financial holdings have stable profits and defensive attributes, making them a safe haven for funds. The stock prices of many financial stocks such as Fubon Gold, Cathay Gold, and CITIC Gold have reached new highs.

U.S. Treasury data showed that China's holdings of U.S. government bonds fell to $590.7 billion in August from $618 billion in July, the lowest since August 2008. Japan's selling of U.S. debt reduced its holdings from $1.1 trillion to $1.07 trillion; the United Kingdom and Canada increased their holdings of U.S. debt, partially offsetting the selling pressure from Asian countries. At the same time, China continues to increase its gold reserves, which increased to 7.747 million troy ounces in September, increasing for 23 consecutive months.

Huang Renxun, CEO of Huida, said at the Berlin event that the AI revolution will continue and has just begun, and will have a positive impact on various industries and countries. It is expected that huge returns on hardware investment will alleviate market concerns about the sustainability of AI spending. Although AI stocks, semiconductor and memory stocks have fallen sharply recently, the Philadelphia Semiconductor Index has recorded its longest losing streak since 2008, and CoreWeave stocks and bonds have both declined.

EU leaders met at a Brussels summit to discuss trade policies to deal with a surge in Chinese exports. A survey by the Forsa Institute shows that more than a quarter of German industrial companies have lost competition to Chinese suppliers, but most companies still regard the Chinese market as an indispensable sales and procurement base.

Affected by the financial reports of the super-large cloud company, the share price of CoreWeave, a company held by Huida, plummeted by nearly 25% in a week. Investors are worried that its US$50 billion debt and revolving financing model may trigger a debt repayment crisis as data center construction slows down, exacerbating the panic selling of AI stocks.

The 2026 Pearl River International Trade Forum was held at the Canton Fair Hall in Guangzhou. The forum focused on changes in the global economy and trade, and discussed the transformation of Chinese enterprises from "exporting products overseas" to "exporting capabilities overseas" as well as the "native globalization" model in the AI era, aiming to promote high-level opening up and international economic and trade mutual trust.
