ICT Test Programming is the key component of effective electronic testing, but it comes with its own set of challenges.
Here in this blog, we will look into the challenges of ICT Test Programming and explore the actionable solutions to overcome them.
Comprehensive test coverage is such a significant challenge. It became a challenge when PCBs grew more complex, making it difficult to test each component and connection.
To close these gaps and make sure important regions aren’t missed, automated tools and design-for-testability (DFT) concepts are used to examine test coverage.
Another big hurdle is the fixture design. It’s important to design an exact bed-of-nails fixture that reliably makes contact with every test point.
The solution to this problem is routine maintenance and careful engineering at the future design phase.
Troubleshooting issues: Testing for PCBs can be challenging and time-consuming. Thus, it is essential to use advanced diagnostic tools that can quickly differentiate between actual defects and issues with the test setup. If you systematically approach the debugging, you can efficiently isolate and resolve the issue.
Besides troubleshooting issues, limited test access is also concerning; as the device shrinks in size, the physical access to the test points becomes more and more restricted.
The solution is to employ boundary-scan testing (JTAG) and other non-invasive techniques to test the inaccessible areas.
Furthermore, for many firms, the high expense of ICT programs and fixtures might be a major deterrent. Purchasing high-quality fixtures and software may appear expensive upfront, but it will save money over time by increasing test accuracy and decreasing downtime.
Over time, regular software and equipment upgrades and updates for testing can also help in reducing these expenses.
