Description

Technical Field

[0001] The present application relates to the field of wave soldering accessories, and in particular to a wave soldering nozzle regulating device. Background Art

[0002] Wave soldering is an electronics assembly technology that relies on bringing high-temperature liquid tin into contact with the soldering surface of a circuit board. During this process, the hot liquid tin maintains an inclined surface and, through a special device, forms a wave-like phenomenon, hence the name "wave soldering." The primary material for wave soldering is solder bar, and its quality is affected by several factors, one of which is the distance between the wave soldering nozzle and the soldering surface.

[0003] Traditional wave soldering nozzle adjustment systems use nozzle baffles that make it difficult to control the height of the nozzle from the soldering surface, which directly affects soldering quality and oxidation. Improper control of the distance between the nozzle and the soldering surface can lead to uneven soldering and increase the risk of oxidation at the solder joints, thus affecting solder joint quality and circuit board reliability. Oxidation is particularly noticeable in lead-free soldering, as lead-free solder has poor wettability, which can easily lead to micro-cracks around the solder joints. Furthermore, the higher soldering temperatures can easily lead to overheating and significant oxidation.

[0004] Meanwhile, the design of the wave soldering equipment is usually compact, especially there is usually only a narrow gap between the wave soldering nozzle adjustment device and the wave soldering equipment body. Utility Model Content

[0027] In an embodiment of the present application, in combination with reference to Figure 1 and Figure 2 The adjusting mechanism 2 further comprises a mounting plate 26, which is horizontally arranged below the adjustable peak welding nozzle baffle 24, and the mounting plate 26 is fixedly connected with the first side plate 11 and the second side plate 12 at two ends thereof.
