Who is this course for

If you plan to connect your life with electronics repair or are already a laptop and personal computer repair technician and want to improve your skills, then training at Bgacenter is for you.
If you are already performing modular repairs and there is a need to master the soldering of bga chips on professional equipment, then we are also waiting for you at Bgacenter.
During the training, you will learn the basics of radio engineering, laptop troubleshooting, circuitry and reading circuits, soldering SMD components and bga chips.
Practice in groups of up to 4 people will help you learn diagnostics, circuitry and soldering quickly.

Customer service

Device repair begins with customer service. You will learn what to pay attention to when taking a laptop for repair. Make your own checklist of the customer service administrator. You will learn how to use specialized programs for service centers.

You will also learn:

- what must be checked when taking a laptop for repair,
- why is it important to record the configuration of the laptop,
- what do external damages of the device case indicate,
- why you should pay attention to the decorative stickers and the condition of the screws of the case.
