There are still many test systems in the field that have long passed their expected life. Customers who have these systems sometimes have to face the problem of repair or replacement if their system goes down. What to do now? In-Phase Technologies, during its many years in the ATE industry, has been approached several times by both new and existing customers to help them out of this bind. With proper documentation, the task is limited to exchanging current available instrumentation for older obsolete units and revising the system software to accommodate the new units. Without proper documentation, it becomes a significant challenge and typically requires starting from scratch once the intended use of the system is clearly understood. In-Phase Technologies has experience in addressing and developing solutions to both of these situations. While the task is sometimes quite difficult, the customer in the long run typically benefits from both a cost and availability standpoint.
