AI Technical Summary

Technical Problem

During the soldering process, the sudden exposure to high temperatures causes accelerated thermal expansion and contraction of circuit boards, resulting in soldering defects such as incomplete soldering, cold soldering, and empty soldering, which affect product quality and increase production costs.

Method used

A preheating device is used to preheat the circuit board. By setting up a heat-conducting plate and a stirring rod in the preheating chamber, the temperature is slowly increased and the molten solder is heated evenly, avoiding direct high-temperature baking of the circuit board. Combined with the fan blades, uniform hot air is provided for preheating to prevent thermal expansion and contraction.

Benefits of technology

It effectively prevents weld defects, improves welding quality and efficiency, and reduces production costs.
