What are Silver Sintering Die-Attach Materials?
Silver sintering die-attach materials are conductive adhesives or pastes that use sintered silver particles to bond semiconductor chips to substrates or lead frames. Unlike traditional soldering, silver sintering forms a porous metallic bond that ensures strong adhesion and superior heat dissipation.
Key benefits include:
- Excellent thermal conductivity for heat-sensitive devices
- High electrical conductivity for efficient power transfer
- Strong mechanical reliability, even under thermal cycling
- Lead-free and RoHS-compliant for eco-friendly electronics manufacturing
These properties make silver sintering die-attach materials especially suitable for high-power and high-temperature semiconductor applications.
