pcb覆铜板的用途
英文回答：
Printed circuit boards (PCBs) are electronic components that are used in electronic devices and systems. They are made of a non-conductive material, such as fiberglass, and have copper foil laminated to one or both sides. The copper foil is then etched to create the desired circuit pattern.
PCBs can be used for a variety of purposes, including:
Connecting electronic components.
Providing power and ground connections.
Routing signals between components.
Shielding sensitive components from electromagnetic interference (EMI)。

PCBs are an essential part of many electronic devices, and they play a critical role in the functionality of these devices.
