Terminal pins are electrical connection components used in various electronic applications. They are typically employed in PCB assembly and wiring to establish a secure and permanent connection between electronic components. A good combination of these properties ensures a reliable and lasting connection in the electronics industry. The recommendation for the size of PCB drill holes is a guideline that should always be considered in conjunction with the nature and structure of the PCB, as well as the processing of the terminal pins. Adjustments may be necessary to achieve an optimal and secure connection, taking into account the specific characteristics and assembly process of both the terminal pins and the PCB. Terminal pins can also be obtained in strip or magazine form for ease of handling and automated assembly processes.
