Wave soldering flux active phase first must have the appropriate time and temperature, allowing the completion of the cleaning stage in the solder particles just begin to melt. Secondly, fully heated slowly to secure the solvent was evaporated, to prevent tin beads formed and limitations of the components caused by the internal stress due to the temperature expansion, causing reliability problems off cracks. The time-temperature curve, the solder melted stage is the most important, and must be sufficient to allow the solder particles is completely melted, liquefied forming a metallurgical welding, residual solvent, and flux residue and evaporated and the surface of the formed solder pin. This stage is too hot or too long, may damage components and PCB.
