Ever wondered how semiconductor chips stay securely attached inside a package?

Eutectic die attach, commonly used in hermetic semiconductor packages, uses a eutectic alloy to bond the semiconductor die to the package cavity.

A eutectic alloy melts at the lowest possible temperature for its specific metal composition, helping create a strong and reliable bond.

Learn more about die attach materials, reliability, testing methods, and semiconductor packaging technologies in this month’s FAQ.

What does a destructive bond pull test actually tell you about bond integrity?

More than wire strength. It reveals how a bond truly behaves under stress and how it fails at its weakest point.

A destructive bond pull test applies a controlled, increasing force to a wire bond until it breaks. The value is not just in the force at failure, but in what the failure mode says about the process.

Performed per MIL-STD-883 Method 2011, this test helps characterize:

✅ Actual mechanical integrity of the wire bond
✅ Failure mode behavior (heel break, wire break, bond lift, etc.)
✅ Process stability across the assembly flow

As a U.S.-based OSAT focused on high-reliability assembly and test, destructive testing is essential to validate process integrity before devices enter mission-critical environments.

What Defines Mission-Critical Performance?
It comes down to how they’re tested.

Through rigorous testing and proven processes, every component is held to the highest standards required by aerospace and other mission-critical applications.

✔ Tested for performance
✔ Verified for reliability
✔ Proven in real-world conditions

When systems depend on every signal, there’s no room for error.
Because what we do matters.

Die shear testing measures the strength of the bond between a semiconductor die and its substrate. This test is critical for:

✔ Reliability – Ensuring the die stays securely attached under stress
✔ Durability – Withstanding vibration, temperature changes, and harsh environments
✔ High-reliability applications – Essential for aerospace, defense, and mission-critical electronics

Proper die shear testing is a key step in quality control and qualification, helping devices perform consistently over time.
