Product Description

Terminals
Overview of PCB Terminals
Definition:
PCB terminals are connectors that provide a means of connecting wires or cables to a PCB. They facilitate electrical connections between the PCB and external components, allowing signals or power to flow.
Types of PCB Terminals:
Through-Hole PCB Terminals:
Description: These terminals are inserted into holes drilled in the PCB and soldered on the opposite side.
Examples: Pin headers,solder pins,and screw terminals.
Applications: Often used in applications requiring robust mechanical strength.
Surface Mount PCB Terminals (SMT):
Description: These terminals are mounted directly onto the surface of the PCB, using solder paste and reflow soldering techniques.
Examples: SMT connectors, small form-factor connectors.
Applications: Commonly used in compact designs and modern electronics to save space.
Screw Terminals:
Description: These terminals allow for the direct connection of wires by securing them with a screw.
Applications: Used in applications where a secure, removable connection is needed.
Spring Terminals:
Description: These terminals use a spring mechanism to hold wires in place, providing a quick and reliable connection.
Applications: Frequently used in automotive and consumer electronics.
IDC (Insulation Displacement Connector) Terminals:
Description: These terminals make contact with the wire by displacing the insulation, allowing for fast and efficient connections without stripping the wire.
Applications: Commonly used in ribbon cable connections.
Applications of PCB Terminals:
Consumer Electronics: Used in devices such as TVs, computers, and smartphones for connecting internal components.
Automotive: Found in wiring harnesses and electronic control units.
Industrial Equipment: Used in control panels, sensors, and machinery.
Telecommunications: Employed in networking equipment and communication devices.
Characteristics:
Material: Typically made from conductive materials like copper or brass, often plated with tin or nickel for corrosion resistance.
