Webinar: Getting started with Embedded JTAG Solutions
Learn about getting started with Embedded JTAG Solutions (EJS), including design-for-test (DFT) requirements and ease-of-use provided by pre-existing models and Automatic Test Pattern Generation (ATPG), simplifying test development and reducing cost compared to traditional methods while enabling a wide range of high performance alternatives.
With rapidly evolving PCBA and SMT technologies, most test engineers responsible for PCBA test in today's electronics manufacturing industry face major challenges that even the most sophisticated and expensive traditional test methods such as ICT and Flying Probe cannot effectively address.
These challenges include diminishing access to components due to increasing densities, covered contacts and lack of test points, as well as the need to test high frequency aspects of board designs sensitive to physical contact. Faced with the ever-increasing cost associated with test equipment, fixtures, and engineering effort required for traditional test methods to keep pace with advancing PCBA technology, it is easy to see that a better way is needed.
Embedded JTAG Solutions (EJS) offer an alternative that is relatively inexpensive and easy to learn, while providing high performance options that are beyond even the most expensive and engineering intensive traditional test methods. Utilization of EJS can provide component access to not only verify physical PCBA integrity but also to leverage on-board resources for high performance embedded test operations.
EJS can reduce the dependency on high cost external test equipment and fixtures while taking advantage of ATPG technology to reduce the test program development effort required to attain acceptable test coverage. With EJS, on-board processors and FPGAs can be accessed, controlled and used to perform test operations on circuit elements they are connected to, including high speed in-system programming of Flash, at-speed test of dynamic memory, at-speed test of high-speed interfaces, and even mixed-signal test functions.
