Top attach in power electronics is the process of bonding a top-side interconnect or component to a semiconductor package or substrate to support current flow, heat transfer, and mechanical integrity. Using advanced silver sintering materials, top attach enables high-reliability electrical and thermal conductivity, ensuring efficient power transfer, improved durability, and enhanced performance in high-power semiconductor and automotive applications where long-term reliability is critical.
Argomax® silver sintering for top attach is applied as a paste or pre-formed film using stencil printing or precision dispensing, followed by controlled low-pressure sintering. This process enables consistent, high-reliability die attach and top attach bonding with excellent thermal conductivity, strong electrical performance, and repeatable bondline control in advanced power electronics and semiconductor packaging applications.
Argomax® silver sintering top attach materials are designed to support RoHS-compliant semiconductor manufacturing, helping enable environmentally responsible, lead-free bonding for power electronics. When verified at the product level for the specific paste or film selected, they meet Restriction of Hazardous Substances (RoHS) requirements - supporting OEM compliance objectives and delivering high-reliability performance for EV, industrial, and advanced high-power electronic applications.
Silver sintering paste is applied in 3D via stencil printing or precision dispensing for complex top attach designs and variable geometries, while silver sintering film is a pre-formed layer used for flat, uniform bonding where consistent placement is critical. Film enables tighter bondline thickness control, lower voiding, and higher repeatability—improving reliability, thermal conductivity, and overall performance in advanced power electronics and semiconductor assembly.
Top attach materials are used across power electronics, automotive power electronics, renewable energy systems, industrial drives, and high-performance computing applications. These industries require durable, high-conductivity semiconductor bonding solutions that deliver superior thermal management, strong electrical conductivity, and long-term reliability for next-generation EV, energy, and advanced industrial systems.
