What is a Printed board / PCB（Printed Circuit Board）?

A Printed Circuit Board (PCB) is a platform used to mount electronic circuits in devices. It consists of a non-conductive material with conductive patterns, typically made of copper, printed on its surface to form the circuit. Electronic components are then soldered onto these conductive pathways, allowing electrical signals to pass through the circuit. PCBs come in various forms such as single-layer, multi-layer, or flexible boards, depending on the application. They are found in nearly every electronic device, including smartphones, computers, and household appliances. The design and manufacturing of PCBs are critical to the performance and reliability of the final product.

Application of Printed board / PCB（Printed Circuit Board）

✅Smartphone
Inside a smartphone, PCBs connect various electronic components like processors, memory, and batteries. Due to the need for high-density circuits, multi-layer PCBs are commonly used.
✅Computer
The motherboard in a computer consists of circuits that connect components like the CPU, memory, and hard drives. These circuits are implemented using PCBs, and advanced design is required to efficiently place components.
✅Household Appliances
PCBs are also used in household appliances such as televisions, refrigerators, and washing machines. They implement circuits necessary for power control and to support the functions of the devices.
✅Medical Devices
Medical devices, such as ECG monitors and glucose meters, use PCBs. These devices require precise circuit designs, and reliability is especially critical.
