All about yield loss

Yield loss is one of the most critical performance and cost drivers in high-precision industries, and particle contamination is often its most underestimated cause.

Particle contamination is not merely a cleanliness issue. It is a yield, reliability and economic challenge.

Even microscopic particles, far smaller than a human hair, can disrupt manufacturing processes, degrade product quality, and trigger cascading failures across complex systems.

Understanding its sources, controlling its spread, and optimizing inspection workflows are essential steps toward maximizing throughput and ensuring high-quality, high-performance outcomes.

Correlation between particle contamination and yield loss

Particle contamination is a significant and well-documented cause of yield loss in semiconductor fabrication, composite aerospace manufacturing, and superconducting accelerator components. The particles involved are often microscopic, and they can enter the process from people, equipment, materials, and the environment.

How particles move in a cleanroom

Contamination doesn't just float. It settles, accumulates, and threatens your process. Discover how three complementary measurements, from airborne counts to surface inspection, reveal the full contamination story your cleanroom is telling, and why our systems are built to help you read it.

The price of non-quality

Yield loss carries a price far beyond scrapped units. The visible costs are only the surface.

How to reduce yield loss

Leading organizations treat surface cleanliness as a measurable, controlled parameter rather than an assumption. They set cleanliness specifications, measure surfaces at critical steps and track trends over time, so they find contamination sources and act before defects reach the product.

Effective root cause analysis

Measuring regularly at critical points in the process, together with statistical process control, catches contamination drift early and helps trace it back to its source.
