Global Pressure-less Silver Sintering Paste Market continues to gain significant momentum, valued at USD 93 million in 2026 and projected to expand at a CAGR of 4.60% to reach USD 127.41 million by 2034. This growth is driven by escalating demand from power electronics, 5G infrastructure, and high-performance LED sectors across key regions.

Pressure-less silver sintering paste represents a breakthrough in electronic packaging, enabling high-temperature bonding without mechanical pressure. Its superior thermal conductivity (up to 250 W/mK) and electrical properties make it ideal for power semiconductor devices, where traditional soldering fails under extreme operational conditions.
