In industrial production and test engineering environments, the documentation and categorization of recurring failures is essential for: Improving process efficiency Increasing product reliability Reducing rework and waste Supporting sustainable corrective and preventive actions Knowing how to correctly classify failures allows attacking the root of problems and building a virtuous cycle
The analysis of test result stability is an essential methodology to ensure that a test system continues to deliver reliable, repetitive, and consistent measurements over time. This practice is fundamental to maintaining the reliability of the production process and avoiding false failure diagnoses. 🧪 Why is result stability so important?
ISO 45001 is an international standard that defines the requirements for an Occupational Health and Safety Management System (OHSMS). Its main objective is to protect employees and prevent occupational accidents and illnesses in work environments — including production lines, test benches, and laboratories. For companies involved in electrical testing, manual
In test engineering, especially in industrial and laboratory environments, ensuring that the results obtained are reliable, traceable, and technically valid is essential. It is in this context that the principles of the ISO/IEC 17000 series and, more directly, the ISO/IEC 17025 standard, an international reference for testing and calibration laboratories,
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
ARINC 664, also known as AFDX (Avionics Full-Duplex Switched Ethernet), is an Ethernet-based communication standard developed to meet the rigorous demands of civil and military aviation. It was created to replace older buses like ARINC 429, offering greater bandwidth, full-duplex communication, and deterministic traffic control. Implemented mainly in next-generation commercial
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
Electromagnetic Interference (EMI) occurs when unwanted electrical signals affect the operation of circuits and electronic systems. It can cause communication failures, instabilities, data loss, and even permanent damage. In the context of industrial production and testing, understanding and controlling EMI is essential to ensure reliability, safety, and compliance with regulatory
The production ramp-up is the critical phase between the pilot and mass production. A small error can cause significant losses. Therefore, it is essential to ensure that all systems, processes, and equipment are technically validated before starting scale production. A safe ramp-up starts with a well-structured technical checklist. And ends
