The Solution For Device Variance
For those extreme alignment challenges, we have introduced the first and only compliant wall production test socket.

The XACT, named for its ability to create the exactly perfect fit for each and every device, uses two compliant walls to align the device in the test pocket.

This compliancy effectively eliminates up to 50% of the positional accuracy compared to the conventional alignment methodology. Because 100% of alignment in QFN testing is done from outside of the package, this solution is tailor made for high volume leadless devices. Lab tests have shown that these walls are extremely durable, lasting as long as the life of the socket.
