Main Board
A Main Board, also known as a motherboard or system board, is the primary circuit board in electronic devices like computers, phones, or TVs. Think of it as the device's central nervous system that connects all other parts together. When repair technicians mention main boards in their experience, they're referring to their ability to diagnose, repair, or replace these essential components. This is a crucial skill in electronics repair since the main board typically controls most device functions and is often the most complex part to work with.
