Introduction:

The PCB (Printed Circuit Board) is an indispensable core component in electronic devices, used to connect and support electronic components, enabling electrical connections and signal transmission in circuits.

PCB Production:

PCB (Printed Circuit Board) is a substrate made of insulating materials (such as FR-4), with conductive copper layers formed on its surface through printing or etching processes to create circuit patterns. Electronic components are fixed onto the PCB by soldering and connected electrically through copper traces.

The main components of a PCB include:
– Substrate (typically made of insulating materials, providing mechanical support and electrical insulation).
-Copper Layer (conductive circuits formed on the substrate through etching processes, used for transmitting electrical signals).
– Pad (metal areas used for soldering electronic components).
– Via (used to connect circuits between different layers, classified as through-hole, blind via, and buried via).
– Solder Mask (a protective layer covering the copper layer to prevent short circuits and oxidation, usually in colors such as green, blue, white, black, or red).
– Silkscreen (text or symbols printed on the PCB surface to identify component locations, part numbers, and other information).
