High-Speed PCB Design Guide XI: How to Improve Testability

As electronic devices become increasingly miniaturized, advancements in component and wiring technologies have created new challenges for production testing. Highly integrated ICs, smaller insulation spacings, and limited access to circuit nodes have made traditional testing methods insufficient. To address these challenges, a design-for-testability (DFT) approach is essential to reduce testing costs and enhance production efficiency. This guide explores the principles, strategies, and best practices for improving PCB testability.
