What is difference between clearance and creepage PCB ?

Printed Circuit Boards (PCBs) are used to create complex that require a precise design to function properly. The two most important terms used in PCB design are "clearance" and "creepage." Although both terms are related to the distance between components, they have distinct meanings and applications.

Clearance refers to the distance between two components, such as the distance between a header and a component lead. Clearance is important because it determines the minimum distance between components to ensure proper electrical communication and to minimize the risk of electrical hazards.

Creepage, on the other hand, refers to the amount of space that a component occupies on a PCB. Creepage is important because it determines the overall width and spacing of the PCB and can affect the ease of routing and the overall aesthetics of the board.

Understanding the difference between clearance and creepage is crucial for ensuring the proper functioning and safety of electronic devices. Clearance should be kept to a minimum, while creepage should be kept to a maximum. By carefully considering the clearance and creepage of a PCB, engineers can create boards that are both functional and visually appealing.
