Soldering SMD components takes place in so-called Reflow soldering mostly in which assembly to be soldered this one runs through up to 6 different temperature zones. Getting the components fixed on the circuit board or connected to the solder contacts on-glazes of the plumb line or the adhesive through this. This production step is possible a one in conformity with the RoHS as well as in a leaded process of soldering at riese electronic just like at the wave soldering.
