Abstract
The invention provides a miniature nitrogen protective solder pump system. A corresponding tin melting cavity of an external heating type lead-free solder machine is a titanium alloy crucible, a heating element is arranged on each face of the titanium alloy crucible, a solder pump is used for delivering molten soldering tin liquid to a soldering nozzle, and a diffuse type nitrogen protection device is used for uniformly guiding nitrogen heated by a nitrogen heating device to flow to from stable soldering wave crests. Requirements on miniaturization and integration of PCB (printed circuit board) soldering equipment are met, and soldering weave crest stability and PCB soldering quality can be guaranteed; lead-free soldering tin consumption is reduced obviously as compared with that of traditional wave-soldering equipment, energy is saved, and generated solder spatter is reduced obviously; an effective nitrogen protective film can be formed, oxidation of liquid soldering tin is reduced effectively, solder joints are protected against oxidation, and nitrogen consumption is decreased effectively; flowability of the liquid soldering tin and particularly the soldering wave crests is guaranteed, and soldering defects due to loss of soldering temperature are avoided effectively.
Description
technical field [0001] The invention relates to a small nitrogen protection solder pump system, which belongs to the technical field of welding equipment. Background technique [0002] Modern electronic soldering technology has experienced the development from through-hole soldering technology to surface mount soldering technology, and from lead soldering technology to lead-free soldering technology. The development and transformation of soldering technology has directly brought about three developments. On the one hand, the number of through-hole components that need to be soldered on circuit boards has gradually decreased. On the other hand, the difficulty of soldering through-hole components has continued to increase. Reliable product requirements. [0003] The welding of through-hole components mainly adopts manual welding and wave soldering. Traditional manual welding is difficult to accurately control the welding temperature, which directly affects the quality of sol...
