One of the most prominent drivers for the silver sintering paste industry is the growing global investment in 5G infrastructure. The paste’s ability to provide superior thermal management and electrical conductivity makes it ideal for power amplifier components and thermal modules in 5G base stations.
Case in point: In May 2025, China successfully conducted the world’s first 5G satellite-to-smartphone broadband video call, illustrating the incredible potential of space-based 5G.
Companies like SpaceX, OneWeb, and Eutelsat are also entering emerging telecom markets like India, opening doors for extensive silver paste usage.
Silver sintering paste is essential in power conversion and onboard charging systems in EVs. As governments worldwide promote clean mobility, the automotive sector is investing in better batteries, faster charging tech, and efficient thermal management, all of which use silver paste extensively.
The industry faces risks from geopolitical tensions and trade restrictions, potentially affecting the supply of raw materials. Additionally, silver prices surged by over 34% in 2024, increasing production costs and creating hurdles for manufacturers.
While silver paste offers premium performance, copper and silver-copper hybrid pastes are emerging as cost-effective substitutes. Moreover, environmental concerns surrounding excessive silver usage may influence long-term regulatory decisions.
Recent product launches have introduced high-efficiency, lead-free, and halogen-free silver pastes designed to meet stricter regulatory and performance standards.
June 2024: Heraeus Electronics launched mAgic® PE360, a LAS paste with enhanced thermal conductivity and reliability.
July 2023: Toyo Ink introduced low-temperature Ag nanoparticle paste, suitable for pressureless sintering applications.
April 2023: MacDermid Alpha launched Argomax 2148, tailored for the EV sector.
