The Connection Mechanism Between The Solder Wire And The Soldering Surface During The Operation Of The Cold Press Pin Crimper

When crimping the contact crimper connector, press down the handle until the ratchet mechanism releases automatically. After this step, the solder wire adheres tightly to the metal surface being soldered.

After the d sub contact crimper crimping is completed, the metal components of the solder wire undergo plastic deformation with the metal surface of the welding end under the action of compressive stress, and the metal atoms on the surfaces of the two are in close contact, thereby forming a continuous conductive channel.

The treatment of the soldered surface determines the final connection quality. Using a solderable metal layer such as tin, silver, or gold plating on the terminal surface further enhances the metal continuity between the solder wire and the terminal.

The entire crimping process involves no high-temperature solder or flux. Step contact crimping tool uses mechanical compression and deformation to "cold solder" the solder wire and terminal together at room temperature. This method is highly practical for field operations and mass production.
