The GPIB, also known as IEEE 488, is a short-range digital parallel communication bus widely used in laboratory, scientific, and industrial environments. It was initially developed by Hewlett-Packard in the 1960s and later standardized by the IEEE as a reliable interface for communication between computers and measurement instruments. Even with
The PXI (PCI eXtensions for Instrumentation) is a high-performance modular platform aimed at test automation, data acquisition, and industrial instrumentation. Based on the PCI bus, PXI offers low latency, high precision, and deterministic synchronization — making it ideal for complex and multi-channel applications. PXI is the gold standard for automated
In the manufacturing processes of electronic boards (PCBA), it is essential to ensure that the products are electrically correct and functionally operational. For this, two main types of tests are used: In-Circuit Test (ICT) and Functional Test (FT). Each has a distinct and complementary technical purpose, acting at different moments
Industry 4.0 represents the fourth industrial revolution, characterized by the complete digitization of production, with integration between machines, systems, and real-time data. Advanced Manufacturing applies these concepts in practice, using smart technologies to optimize production processes. This new era connects autonomy, efficiency, traceability, and data-driven decision-making — transforming traditional factories
Test Engineering is the branch of engineering that develops and implements systems, procedures, and tools to verify the functionality, quality, safety, and performance of a product or system. It is present in various sectors — electronic, automotive, medical, aerospace, cosmetic, industrial — and plays a critical role in ensuring technical
Instrumentation is the set of devices, systems, and techniques used to measure, acquire, control, and record physical or electrical variables of a system. In the context of AJOLLY Testing, instrumentation is the central pillar to ensure precise, reliable, and traceable tests in industrial, laboratory, and research & development (R&D) environments.
In addition, AJOLLY Testing provides advanced test data analysis to identify failure root causes related to the process, machine, or operator, using essential indicators such as: FPY (First Pass Yield) – tracks yield loss at first test cycle. Top Failures – statistics of most frequent failure modes. CPK (Process Capability
Test software is an essential tool to automate, standardize, and record verification and validation processes in various sectors: industrial, scientific, laboratory, automotive, medical, aerospace, and technical services. Definition A test software is a program developed to control measurement instruments, execute automated test sequences, capture data, and generate reports reliably. It
The terms DUT (Device Under Test) and UUT (Unit Under Test) refer to the unit, module, product, or system being subjected to tests, measurements or validations during a testing process. This unit can be electronic, mechanical, electromechanical, optical, RF, pneumatic, or hybrid, depending on the application sector. The DUT/UUT is
The validation of a product or system requires different types of tests, depending on its application sector. Each segment has its own criteria for compliance, traceability, and technical requirements. Below, we detail the most common types of tests organized by sector, based on the practical experience of AJOLLY Testing. 🏭
