The Trump administration of the United States has targeted ZTE and Huawei in mainland China, and conducted technical export controls and investigations respectively. It was interpreted as restricting the development of 5G communications in mainland China, which has been ahead of its time. This shows its importance. Taiwanese PCB industry is also actively investing in 5G applications. , In the past few days, Dongfang Textile and Hitachi Chemical Chengdu came to Taiwan to roll a kick.

The focus of Japanese investment in Taiwan lies in the upstream raw materials of PCB, including CCL and glass fiber cloth industry, and is mainly also rushing to attack the high-frequency, high-speed and signal but lost PCB raw materials required for the upgrade of the soft and hard board process, including Hitachi Chemical announced that it will invest about NT$2 billion to set up a subsidiary in Taiwan, and build a high-performance laminate (CCL) for PCB in the factory area, mainly for 5G and advanced driver assistance systems (ADAS) , artificial intelligence (AI) and other applications.

Nitto Boseki, a major Japanese glass fiber manufacturer, will also publicly acquire up to 35.22% of the equity of Jianrong Industry at a premium of 10% because of its interest in the development of 5G communications. If Jianrong's largest legal person shareholder, Chuangyou Investment, sells and transfers 14.88% of Jianrong's equity to Nittobo, Nittobo's highest shareholding in Jianrong will exceed 50.1%.

People in the PCB industry pointed out that it is one thing for Nittobo to acquire more than half of the equity in Jianrong Industry to win the operating rights. It is a secondary base for the original production in Japan, and 5G application products are still produced in Japan.
