The main purpose of thickened copper plating is to ensure that there is a sufficiently thick copper coating inside the hole, ensuring that the resistance value is within the range required by the process. As a plug-in component, it is used to fix the position and ensure the connection strength; As a surface encapsulated device, some holes only serve as conductive holes, playing a role in conducting electricity on both sides.
