The FPY (First Pass Yield), or First Pass Yield, is a fundamental indicator of the efficiency and quality of a test or production process. It measures the percentage of units that pass the test on the first attempt, without the need for rework, repetition, or correction. Why is FPY important?

In production testing, validation, and quality control, correctly defining the tolerance limits is one of the most critical factors to ensure reliability, repeatability, and yield (FPY). The test tolerance represents the acceptable margin of variation between the measured value and the expected nominal value, taking into account natural imperfections of
The production ramp-up is the phase in which a company transfers its product from engineering to scale manufacturing, starting production progressively until reaching the planned nominal volume. This moment is critical as it marks the real validation point of the project, processes, production tools, and supply chain. 🎯 Ramp-up Objectives
The Testability Analysis (TSA – Testability Study & Analysis) is a technical process carried out during the development of a product, aiming to verify if all testing and quality control requirements can be effectively applied in the production phase. This analysis is crucial to prevent the product from being inadequately
The terms jig and fixture are widely used in the industry to describe auxiliary mechanical devices in the process of assembling, securing, or testing products. Although often used as synonyms, they have distinct technical purposes. Understanding the difference between jig and fixture is essential for designing efficient and standardized testing
Good Manufacturing Practices (GMP), are a set of standards and guidelines that ensure products are manufactured with quality, safety, and traceability, minimizing risks of contamination, failures, or deviations. These practices are required by regulatory bodies such as ANVISA, MAPA, FDA, and ISO for sectors like food, cosmetics, pharmaceuticals, electronics, and
PPM means Parts Per Million (in English Parts Per Million) and is a metric used to measure the defect rate in a production process or testing system. PPM indicates how many defective parts exist per million units produced, being one of the main performance indicators in quality. The lower the
The standardization of repair processes involves defining and applying consistent and traceable technical procedures at all stages of diagnosis, intervention, and validation of defective products — whether in repair centers, production lines, laboratories, or after-sales. With well-defined flows, the company ensures quality, safety, repeatability, and cost reduction with rework and
