Laptop Repair Chip Level Training

Laptop Lab, Chip-level Training will be customized for your present knowledge of electronics. power electronic components will be introduced before we move to the logics section. First session will get you familiarized with the tools for the lab including the heat blower, Cathode Ray Oscilloscope , Infrared Heater , Micro Soldering Station , BGA rework station Etc.
Power electronic knowledge is imparted with training session on SMPS and LCD monitor . After you become comfortable with power electronics the logic session follows . It is an intensive coverage into the intricate details of chip-level service of the laptops and also desktop Motherboards. This involves detailed circuit tracing , signal analysis , replacement of SMD devices , hands on session on imported production line BGA Rework station and BGA reballing equipments and all the tips and tricks our service engineers acquired from the years of experiences. the session makes you confident enough to chip-level service the new generation notebooks and net-books in the industry
