The pins on a circuit board are commonly referred to as "PCB pins." These pins serve the primary function of transmitting electrical signals between electronic components and the circuit board, ensuring the proper operation of electronic devices.

The main role of PCB pins is to relay electrical signals and control current. Typically crafted from conductive metals such as copper, nickel, or gold, these pins possess excellent conductivity. The shape and size of PCB pins vary based on their purpose and their placement within the circuit board. For instance, they are fixed into holes on the board, transmitting electrical signals between electronic components and the circuit board. The hollow section of these pins allows wires or other conductive materials to pass through, establishing circuit connections. In addition to their connectivity function, hollow pins also aid in securing electronic components, preventing their loosening or detachment.

During the fabrication of circuit boards, electronic components are usually soldered onto the board, and PCB pins play a crucial role in this process. Firstly, they act as conduits for electrical signals, linking electronic components to the circuit board, enabling signal transmission and control. Secondly, PCB pins support and secure electronic components, preventing them from dislodging or shifting during operation. Moreover, these pins enhance the mechanical strength and durability of the circuit board, enabling it to withstand certain external impacts and vibrations.

In essence, PCB pins represent a vital electronic component that plays an indispensable role in the production and maintenance of electronic devices. They not only facilitate the transmission of electrical signals between electronic components and the circuit board but also enhance the board's mechanical strength and durability, ensuring the proper functioning of electronic devices.
