Applications
System-in-Package (SiP) and Heterogeneous Integration Assembly (HIA)
Advanced semiconductor technology, including system-in-package (SiP) and heterogeneous integration, involves combining various semiconductor devices into a single package to improve functionality, performance, and reduce form factor—while remaining cost-effective. SiP, a form of heterogeneous integration, enables the development of complex systems for high-performance devices. At Indium Corporation, our deep understanding of technology and processes allows us to create high-quality soldering products, including SiP solder paste, semiconductor fluxes, and high-performance thermal interface materials. These innovations ensure reliable electrical, mechanical, and thermal connections within integrated systems.
Overview
Proven Solutions to Solve Current and Future HIA Challenges
Miniaturization and the demand for enhanced functionality are making HIA and SIP more popular, driving the need for further development of these technologies. These growing needs present challenges for OSATs in package design, requiring high-performance thermal management materials and designs for more efficient heat dissipation, as well as true no-clean fluxes and fine powder solder pastes due to shrinking standoffs.
