Board Bring-Up is the process of initializing a newly designed or manufactured printed circuit board (PCB) to make it operational. It involves testing and debugging hardware, firmware, and software components to ensure that the board is functioning as intended. Board Bring-Up is crucial because, without it, the board will not function or deliver the desired results. This process requires specialized skills, knowledge, and experience in hardware and software design, debugging, and testing. Professional board bring-up is done by highly skilled and trained engineers who can troubleshoot board problems and ensure that the board meets its intended purpose.
