JOB ROLE

It is generally observed that institutionally trained youth have not produced desired result because training imparted in institutions alone is not enough for acquisition of skills but needs to be supplemented by training in the actual world of work.

Maintenance is a supporting function in an organization. Productivity is a key strategy for manufacturing companies to stay competitive in a continuously growing global market. So, increased availability of production equipment is crucial for competitiveness and to achieve increased availability, a good maintenance strategy is necessary. The literal meaning of maintenance as “the work of keeping something in proper condition” declares that maintenance should be actions taken to prevent a device or component from failing or to repair normal equipment degradation experienced with the operation of device to keep it in proper working order.

The Electronics Technology is undergoing rapid strides of change and there is need for regular monitoring of the national and international technology scenario

When faulty equipment is received from a customer, an assessment of the nature of the complaint is made. An estimate for service/repair charges is made after checking the availability of components. Then through a systematic approach the actual fault is found and rectified. The repaired equipment checked thoroughly and it is handed over to the customers. Minor repairs may be carried out at the premises of the customer itself. The repair and servicing of majority of communication electronic equipment is undertaken by the skilled technicians.

Electronics Fitter, General fits, assembles and repairs various kinds of electronic equipment in factory or workshop or at place of use. Examines drawings and wiring diagrams; checks parts for accuracy of fit and minor adjustments; assembles parts or mounts them on chassis or panels with aid of hand tools; installs and connects wiring, soldering joints equipment, diagnoses faults with aid of electronic testing equipment; dismantles equipment if required and replaces faulty parts or wiring.

Electronics Fitter, other include all other workers engaged in fitting, assembling, repairing and maintaining electronic equipment, machinery, appliances, etc., not elsewhere classified

Electronic Equipment Mechanic repairs electronic equipment, such as computers, industrial controls. Tests faulty equipment and applies knowledge of functional operation of electronic units and systems to diagnose cause of malfunction. Tests electronic components and circuits to locate defects, using instruments, such as oscilloscopes, signal generators, ammeters and voltmeters. Replaces defective components and wiring and adjusts mechanical parts, using hand tools and soldering iron. Aligns, adjusts and calibrates testing instruments.

Mechanic Communications equipment maintenance make sure that communication devices such as land line phones, cellular phones, computers and 2-way radios work properly. Most have an area of specialization, such as cellular technology, and install and maintain the equipment for customers. Many communications equipment technicians work in hubs known as central offices where they make sure information transmitted by the devices is routed and sent correctly
