Technical Field

[0001] The present invention relates to a manual auxiliary welding device for a circuit board, belonging to the technical field of mechanical engineering. Background Art

[0002] Circuit soldering is a crucial aspect of electronic design. While technological advancements have led to reflow soldering being used for commercialized circuit boards, which boasts the advantage of completing all solder joints simultaneously, selective soldering is generally preferred to avoid damage to temperature-sensitive components. However, manual soldering is still used for non-commercialized circuit boards, and it will always play a significant role. Manual soldering is unavoidable in DIY, homemade circuit boards, and circuit board debugging. Manual soldering, however, is often performed without dedicated soldering equipment, and the circuit boards are soldered directly onto a flat surface. This presents numerous practical inconveniences, such as soldering multi-pin chips. Because the circuit board is not fixed, it becomes uneven after soldering other components. Furthermore, the oscillation of the circuit board can make it difficult to align the multi-pin chip with the pins. Consequently, a more convenient method for manual soldering is urgently needed.
