Frequently Asked Questions
What is die attach material in semiconductor packaging?
Die attach material is used to bond a semiconductor die to a substrate or leadframe while providing mechanical stability and efficient heat dissipation in semiconductor packaging. Our PFAS-free die attach materials - including silver, copper, conductive, and non-conductive options - deliver reliable adhesion, strong thermal performance, and sustainable solutions for advanced semiconductor assembly applications.
How does the sintering process work in semiconductor die attach?
Sintering in semiconductor die attach is a solid-state bonding process in which fine metal particles fuse under controlled heat and pressure below the metal’s melting point. This process forms a dense, conductive joint with strong thermal conductivity, mechanical strength, and high-temperature reliability. In power electronics and semiconductor packaging, sintering enables high-reliability die attach solutions with stable performance, improved thermal management, and long-term durability in demanding applications.
What does conductive die attach do in semiconductor packaging?
Conductive die attach provides both mechanical bonding and an electrical path between the semiconductor die and substrate, enabling efficient current flow and heat dissipation. It plays a critical role in power electronics and advanced semiconductor packaging by improving thermal management, electrical conductivity, reliability, and overall device performance in high-performance applications.
Are semiconductor die attach materials RoHS compliant?
Yes, our semiconductor die attach materials are designed to meet Restriction of Hazardous Substances (RoHS) requirements, supporting global electronics compliance and sustainable semiconductor manufacturing. These solutions help reduce environmental impact, improve supply chain transparency, and support EH&S and industry sustainability goals. Product-level compliance should be confirmed for the specific conductive or non-conductive die attach material selected for advanced packaging applications.
