Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, in particular to a selective wave soldering device with a double-track double-speed conveying device. Background Art

[0002] Wave soldering is to make the soldering surface of the plug-in board directly contact with high-temperature liquid tin to achieve the purpose of soldering. The high-temperature liquid tin maintains an inclined surface, and a special device is used to make the liquid tin form a wave-like phenomenon, so it is called "wave soldering". Its main material is solder bar.

[0003] When the plug-in board is welded, it needs to be preheated during the preheating period before entering the welding area.

However, the sizes required for the plug-in board when used in different equipment are also different. It is difficult for existing wave soldering equipment to adjust the size of the conveying device according to the size of the plug-in board to meet the needs of receiving plug-in boards of more sizes.
