Description

Technical Field

[0001] The invention relates to the technical field of welding, in particular to a welding device for electronic components of an electric connector. Background Art

[0002] Electrical connectors, also known as electronic connectors, generally refer to connection units between various electronic components. They are mainly used for the connection and transmission of electronic signals from chip to circuit board, circuit board and circuit board to box. Electrical connectors usually contain chips. The main function of these chips is protocol matching. Through them, the transmission specifications and capabilities of the cable itself can be confirmed. These chips ensure that the electrical connector can effectively transmit current or signals, thereby ensuring the normal operation of electronic equipment.

[0003] The SOP16 package is suitable for various compact electronic products due to its small size and moderate pin spacing. When welding the existing electronic component SOP16 package and the circuit board, many manufacturers use manual welding for processing due to its small size, and use a larger welding head to complete the soldering of the electronic component's solder wire at one time. This processing method is not only inefficient, but also the small size of the SOP16 package makes it difficult to accurately control the amount of tin solder rods, which can easily cause damage to the circuit board and chip, and is time-consuming and labor-intensive. In addition, long-term inhalation of harmful gases generated during welding can cause damage to the human body, and the solder joints stained by the welding head will affect the next welding and must be cleaned.
