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
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. 🏭
