AMETEK Develops Automated Remote Functional Test System For Use in Environmental Stress Screening

06 June 2018

AMETEK VTI Instruments announces the successful development of an Automated Remote Functional Test System for use during the environmental stress screening (ESS) of electronic modules and sub-systems. The architecture of the new test system is based on AMETEK VTI Instruments’ FlexSys™ Series of common core automated test equipment (ATE) solutions.

The test system was envisioned, designed, developed, integrated and tested by AMETEK engineers based in Source: AMETEKSource: AMETEKIndia for Tata Power Strategic Engineering Division's (SED) environmental testing lab in Bengaluru. This joint effort reflects AMETEK’s commitment to a “Make-in-India” initiative, which was launched as a way to transform India into a global design and manufacturing hub.

Prior to the development of this new system, the standard qualification procedures required the Tata Power SED’s acceptance team to be on site to witness the functional tests each time the ESS testing cycle was performed. However, this requirement often created delays in the overall delivery schedule, as scheduling constraints among members of the acceptance team made it difficult for them to be physically present in the environmental test lab when tests were to be conducted.

In contrast, the infrastructure of the new system allows the acceptance team to control and monitor qualification tests remotely, saving both time and money by eliminating the need to travel to the test lab to witness the tests. Observers can monitor the entire test run through a live video feed and control the tests via a web-based software interface. The new system also allows the testing team to record the entire test cycle and test reports for future reference.

For the acceptance team, the Automated Remote Functional Testing System has helped them improve the quality of its products by minimizing the opportunities for human error, reduced test times, and improved product testing throughput. At the same time, the new system has enhanced the quality and repeatability of the tests performed, thereby increasing confidence in the accuracy of the test results.

The Tata Power SED technical team appreciated the speed at which the AMETEK team was able to grasp the requirements and execute the project. Tata team further acknowledged AMETEK’s technical competence and ability to solve complex interface related issues, enabling the project to move through the concept proving and testing phases quickly.

FlexSys™ ATE systems

FlexSys ATE systems are scalable, integrated test and measurement systems designed for use in medium- to high-mix production environments. In addition to boosting test throughput and reducing floor space requirements, the systems are designed to preserve signal integrity through the entire test system, including cabling and signal switching to the user interface, maximizing the performance of the test instrumentation.

FlexSys systems offer manufacturers a new approach to minimizing their capital equipment and system development costs by providing fundamental ATE building blocks of pre-engineered components, which reduces development costs and speeds time-to-readiness. These systems are configured from precision power, instrumentation and switching blocks produced by AMETEK Programmable Power and AMETEK VTI Instruments.

Applications for the systems include aerospace/defense, environmental stress screening (ESS), and electronics manufacturing testing.
