Laptop Chip Level

Technician Level Course (Min 3 hrs to 8 hrs class) : Laptop Chip Level

Laptop chip level Training includes the repair of motherboard component by analyzing the problem in the mother board and solving the problem with replacement of different components.

For this purpose a person should have a good knowledge on all the components and equipment like hot air gun, soldering iron, digital oscilloscope, Component tester, BGA rebelling machine etc. are must. Alliance is providing all this equipment to make the practical training to learn the best laptop chip level Training in Kathmandu Nepal. Chip level repairing courses in Nepal was started first by the alliance and already had made a numerous no of student as a skilled person. Alliance is Nepal top laptop Repairing and training center since a decade.
