Subsidiary of Gripm Advanced Materials Co., Ltd.(688456.SH) has verified the new nanoscale copper powder product with customers and started small-scale supply.

Gripm Advanced Materials Co., Ltd. (688456.SH) announced that its wholly-owned subsidiary, Chongqing Youyan Heavy Industry New Materials Co., Ltd., has made a breakthrough in the key technology for the preparation of highly active nano-copper powder. The new product, highly active nano-copper powder developed by the subsidiary, has been verified by a leading electronic slurry company. The copper-based slurry can be sintered at 200C, with a shear strength exceeding 50MPa and a resistivity of less than 5u*cm, meeting the design requirements of copper slurry products. Verification reports from customers confirm that compared to similar types of nano-copper powder domestically and internationally, the sintering performance of this nano-copper powder is superior, reaching an international leading level and meeting the high-end raw material requirements for low-temperature sintering slurry materials in electronic slurries, expanding the product application field and gaining high recognition from customers. The company's new product, highly active nano-copper powder, can be widely used in new copper-based slurry materials products for PCB interconnection, power chip packaging and assembly, with end applications mainly in integrated circuits, third-generation semiconductor packaging, advanced electronic components, photovoltaics, and other fields. The product is now available for small-scale supply. In recent years, the company has increased its efforts in scientific research and development, actively undertaking major special tasks such as future industries designated by the State-owned Assets Supervision and Administration Commission, accelerating product structure adjustments and corporate industrial transformation and upgrading, focusing on additive manufacturing and electronic slurry fields. The successful development of this product has enriched the company's product line and technological reserves, further consolidating the foundation for the company's advancement into the electronic slurry field. The company's acquisition of new product orders is a recognition of the company's technical capabilities and market competitiveness by customers, which will help enhance the company's influence in the field of low-temperature sintering slurries, promote further expansion of related products, and have a positive impact on the growth and sustainable profitability of the company's electronic slurry business.
