The complexity of circuit boards continues to increase, often in conjunction with smaller and smaller sizes. Both of these trends make it difficult, if not completely impractical to manually test PCBs in most cases. Consequently, CMs rely on automated equipment, such as Flying Probe apparatus, to efficiently and accurately perform functionality test measurements. These and other necessary tests, require that design for testing (DFT) guidelines and actions be known and implemented to avoid failure modes that can derail your PCB development process.
This eBook answers the following questions:
- What are the most common automated inspections and testing used by manufacturers to verify your board?
- When to incorporate DFT into the design process and what stakeholders need to include to ensure all necessary concerns are considered?
- Where to best place test points during layout design to help facilitate testing?
- Why is it so important to test and identify faults during development; instead of after deployment?
- How can you utilize PCB layout design tools to implement DFT?
