Test Systems
Testing is more than just finding defects on Printed Circuit Boards. It is also about how to predict defects before they occur. A true economy can only be achieved when you see testing as an integrated part of manufacturing. To achieve this we provide Advanced Diagnostic Tools and Electronic Manufacturing Systems (EMS) that integrate testing with design, manufacturing, and repair.
