How to Evaluate a PTI    PDF version

Double Ended Spring Probe Interface Tower                            

Accurate testing requires an outstanding electro-mechanical interface between tester and probe card. Understanding the complex interface requirements, we engineer our Prober-Tester Interfaces (PTI) with superior electrical and mechanical characteristics to deliver consistently accurate test data.

Mechanical Precision
Sophisticated, tolerancing methodologies employed during the design and manufacture of each PTI ensure consistently accurate electrical spring-contact-to-pad alignment. In addition, each PTI delivers uniform pin compression within each circumferential row. The mechanical precision of the Xandex PTI ensures that this product will perform reliably, even under the toughest conditions.

Electrical Performance
The Xandex PTI transparently delivers test signals with extremely high fidelity. This PTI has been designed and characterized as performing well beyond the operational frequency range of most testers. Extended frequency range ensures accurate, distortion-free signal transmission.

Robust Design
Quality engineering and construction ensures there will be minimal maintenance required during each PTI’s lifetime. The tough outer casing is constructed of solid, hard-anodized aluminum. Only stainless steel hardware is used in each PTI’s construction thereby protecting your clean-room environment. Accidentally damaged, spring-contact pins are easily replaced.

The Integrated Solution
The PTI seamlessly integrates with all of the Xandex AutoLoader 2 probe card changing systems. The AutoLoaders perform precision probe card changes in a matter of seconds, and Xandex’s PTI provides the crucial electrical and mechanical link between the prober and tester. The superior performance of this integrated system leads to reduced downtime and increased operator satisfaction. Avoid multi-vendor complexities by utilizing Xandex’s complete solution. Get it right the first time.

Flexible Systems
Xandex is well known for customized sort floor solutions. The Xandex PTI is no exception. This unit is adaptable to multiple probers/tester platforms. In addition, Xandex will work with you to build any custom system required for your needs. Whether you require a PTI design for a new tester, or the enhanced productivity of retrofitting your existing system call Xandex, your partner in wafer sort.
