Prerequisites:
Preferably, the student should have completed the basic Trillium Maintenance Course and have at least 3 years of experience on the LTX Trillium Testers.
Course Overview:
This course is designed to teach the Maintenance Technician troubleshooting techniques beyond what the basic Trillium Maintenance Course covers. The graduate will also have an understanding of systems operation and theory known only to a few individuals in the world. They will be knowledgeable in advanced troubleshooting techniques and test equipment usage. When armed with the right documentation, advanced knowledge, and troubleshooting skills, the graduate technician becomes a valuable asset to any test floor.
