Group 1 - The core viewpoint of the article emphasizes that Low CTE electronic cloth is a key material for advanced AI packaging, significantly reducing warpage and stress mismatch, thereby enhancing long-term reliability. The demand for Low CTE electronic cloth is expected to surge due to the explosive growth in AI computing chip shipments and the increasing size of chip packaging areas, alongside rising demand for smartphone motherboards [2][18]. Group 2 - The demand explosion for Low CTE electronic cloth is driven by two main factors: the packaging of AI computing chips and the upgrade of consumer electronics. The application scenarios include AI servers, data center switches, and high-end consumer electronics. The demand for Low CTE electronic cloth is projected to exceed 600 million meters by 2025, with a compound annual growth rate of nearly 100% [18][19]. Group 3 - The supply of Low CTE electronic cloth is currently scarce, with Nitto Denko being the leading global supplier. However, its production capacity is not expected to increase in the short term. Domestic companies like Zhongcai Technology and Honghe Technology are beginning to fill the gap, having completed customer certifications and started mass production [3][6][12]. Group 4 - The article highlights that the Low CTE electronic cloth market is characterized by a concentrated supply structure, with ongoing shortages expected to worsen. The demand for Low CTE electronic cloth is anticipated to double this year, reaching over 6 million meters, while the supply gap is projected to exceed 30% [6][12]. Group 5 - The production of Low CTE electronic cloth involves high technical barriers, with only a few companies globally mastering stable mass production technology. The production process includes multiple stages, such as melting, weaving, and post-treatment, each facing various technical challenges [13][14][17]. Group 6 - The article discusses the advanced packaging technology CoWoP (Chip-on-Wafer-on-Substrate) as a significant growth area for Low CTE electronic cloth, particularly in AI servers. This technology allows for larger and more integrated packaging, which is crucial for AI applications [3][34][53].
