  INTRODUCTION

This Concept of teaching Chiplevel Repair of Laptops and Desktops is first time else where in the world.

Here we teach in systematic way to the students from basic to BGA level by preparing them in a world class environment. The teaching staffs have a background of electronics and communication graduation with more than 20 years of chip level repairs experience backup. So here students not only understand the basic electronics, basic working phenomena of laptop and desktop motherboards which is an essential for this profession to learn the real practical experience of repair. We organized ourselves in such a way that we concentrate on each student by understanding his/her capability and teach according to it. We also have an infrastructure in such a way that each student will have their own individual testing equipments and tools to concentrate and learn in proper way during course period. So this course is not only suitable to the fresh students but also to the people who are already in the field and struggling to understand the systematic concept of repair. We assure that we build 100% confidence and fulfill your dreams to become an expert service engineer.

We also guide the safe and quality accommodation for out of state and out of country students, during your stay for the course with us.
