Impact of Dust on Printed Circuit Assembly Reliability

Atmospheric dust consists of solids suspended in air. Dust is well known for its complex nature. It normally includes inorganic mineral materials, water soluble salts, organic materials, and a small amount of water. The impact of dust on the reliability of printed circuit board assemblies (PCBAs) is ever-growing, driven by ...

Latent short circuit failure in high-rel PCBs caused by lack of cleanliness of PCB processes and base materials

Latent short circuit failures have been observed during testing of Printed Circuit Boards (PCB) for power distribution of spacecraft of the European Space Agency. Root cause analysis indicates that foreign fibers may have contaminated the PCB laminate. These fibers can provide a pathway for electromigration if ...

What defect in SMT were cuased by dust contamination? -- Does anyone know what defect in SMT will be caused by dust contamination? What dust level in SMT environment is recommended? Recently an audit come to factory and ask we must control the amount of dust. Why SMT line need to control the dust level?

Using machine data for predictive maintenance (inc retro fitting sensors on smt machines) -- There are software companies out there who can help predict when SMT machines will falter or help identify line utilisation losses. They use sensors as and when required with certain machines. Are there companies also looking to do this? What has their experience been? Are you planning to? Cheers
