Introduction:
Crest welder refers to the soft soldering material will melt tin alloy (lead), electric pump or electromagnetic pump flow into the design requirements of solder wave, can be formed by the injection of nitrogen to solder pool, make the PCB with components in advance through the solder wave, components and PCB solder welding end or pin of the mechanical and electrical connection between soft soldering.

Crest welder refers to the soft soldering material will melt tin alloy (lead), electric pump or electromagnetic pump flow into the design requirements of solder wave, can be formed by the injection of nitrogen to solder pool, make the PCB with components in advance through the solder wave, components and PCB solder welding end or pin of the mechanical and electrical connection between soft soldering. There are many types of wave soldering systems depending on the geometry of the crest used by the machine.
Features:
Smooth peak without rotation component: because the three-phase asynchronous induction electromagnetic pump produces linear thrust rather than the rotating thrust of the blade of the mechanical pump, the wave peak is smooth, the tin tank level disturbance is small, and oxidation is slight.
Stable wave peak: due to the induction pump technology, combined with the voltage stabilization principle, when the grid voltage fluctuates by 10%, the voltage on the induction pump fluctuates by nearly 3%, so the wave peak is stable.
High efficiency: three-phase asynchronous induction electromagnetic pump because there is no pulsating magnetic field component, so the efficiency is greatly improved, to develop the prototype show, the peak width of 400mm, peak height of 40mm. And the three-phase induction pump's magnetization current is only about 5A, such working conditions ensure that the three-phase asynchronous induction pump works in the state of low heat and low current load, to ensure the long-term reliability of life. No moving parts, no wear and tear, truly realize the maintenance free, eliminating the regular maintenance link.
