Abstract :
A novel soldering process named ´clean soldering´ is described. It is a soldering process in an inert gas atmosphere with a specially composed residueless flux. This process does not require any washing and cleaning operation. It is suggested that it will contribute to the solution of the pollution problem of organic solvents. The products manufactured by this soldering process have sufficient insulation resistance, are suitable for high-density PCBAs (SMT), reduce the defects in soldered joints, prevent oxidation of solder baths, and are safe for the human body.<>
