RF technology and sub-assembly repair

MS712  - 40 hours to 70 hours

Learning objectives

To provide RF principles diagnostic methods for generators, RF matches and plasma.
Introducing basic preventive and corrective maintenance procedures.
Health and safety.


Who will benefit most ?

Maintenance staff with electronic background.


Innovative teaching resources

Training can take place at your site using your equipment. Our training has been developed to provide a high percentage of hands-on exercises in conjunction with data collection and understanding of information recorded. Training can be divided into several blocks allowing you to arrange time for production needs.
In between training blocks your staff can put into practice what they have currently learned and can share their experience during the next phase training. Our training instructor is available to audit your staff once the training has taken place. This will be used as an evaluation on skills learned to further improve your ability to become self-supportive.
Please contact 40-30 training department to discuss your training needs.
