What is Major Defect
Major defect refers to a type of flaw or imperfection that has the potential to significantly impact the functionality and usability of a unit or product. These defects are deemed major due to their likelihood of causing failure in the intended purpose of the PCB. Major defects can arise during the PCB assembly process and may be caused by various factors such as electrostatic discharge (ESD), misaligned layers, short circuits, or crossed signals.
Major defects can have severe consequences, not only in terms of the performance and reliability of the PCB, but also in terms of the overall time to market. Addressing major defects requires dedicated efforts from teams involved in the assembly process, as rectifying these issues can be time-consuming and may involve extensive troubleshooting and corrective measures.
