What is Known Good Board (KGB)
A known good board (KGB), or a golden board, signifies a board or assembly that has undergone thorough testing and verification to ensure it is free from any defects. The KGB serves as a benchmark for quality control, providing a standard unit against which other PCBs can be compared. It is vital in developing test programs, serving as a reference for learning and debugging. Establishing a defect-free KGB makes it possible to identify and rectify any issues or discrepancies in other PCBs, ensuring optimal performance and functionality.
