Mobile Chip Level Training

Mobile phone  Repair Training in Nepal is the most relevant and necessary training in today’s world. As everyone carries mobile phones and trustful repairing is always an issue. In today’s world, it’s hard to find people without smartphones since it has been part of our life. With the pace of technology, there is a need for professionals who can address the issue. People always seek for a reliable place to find and solve the problem of new technology.

We provide the best mobile repair training in Kathmandu. We provide training in major cities like Pokhara, Dhangadi, Butwal and other cities. We provide reliable services to fix the problem. Guru has professional teachers and equipment to train students. GURU pioneers in Smart Technology and Engineering with a ‘Skill Development Program’. We providing opportunities to learn via live project exposures and real-time working culture. Guru is always head in mobile phone repair training in Kathmandu.

We follow the standard operating procedures “SOPs”. The device is checked, diagnosed, evaluated for cost. After that, the required services are executed. Software problem troubleshooting, hardware repair are executed. After that, test the faulty set and finally time stamp to claim the warranty period. We infix the latest version device software, firmware, repairing components. The component is resistors, capacitors, and IC (Integrated Circuit) chips from trusty vendors. We follow an international practice through which students can practice their skills anywhere. The students from GURU can compete around the world without getting biased.

We welcome everyone willing to join our academic training chip level repairing program. There is no bound to those willing to study. There are no criteria to join our program. Yet, a small skill test is conducted and counseling is done. The test is taken to help the students reach their goals and strengthen their weaknesses. After that classes of different modules are undertaken followed by the tests. Finally, the student is allowed to work as “On the Job Training” practitioner in a service center. Students here could master their mobile repairing skills in the relevant domain.
