Eutectic Die Attach Paper

Optimizing High Power GaN Device Performance With Eutectic Die Attach

StratEdge has introduced a line of packages for the extreme demands of GaN devices and developed a eutectic die attach process that produces extremely thin, low-void bond lines between the device and package heat sink. We also provide the same service for die-on-tab. Click to learn more about the 6 micron thick, AuSn die attach process that produces >96% coverage.

StratEdge Corporation Packages Used in Mars Rovers

Did you know that StratEdge packages are used in generations of the Mars Rovers?

The Mars Exploration Rovers Spirit and Opportunity were sent to explore the surface of Mars in 2003, and now the most recent Perseverance Rover. To transmit signals and information back to Earth, the rovers were equipped with the power amplifier packages from StratEdge. The amplifier system was designed to protect the gallium arsenide monolithic microwave integrated circuits (MMICs) to ensure true signal integrity. All signals that are transmitted go into the StratEdge package through the chip, and back out the package.Read More
