Newly manufactured printed circuit boards (PCBs) must be cleaned to remove excess solder, rosins and other contaminants before placed into use. An ultrasonic cleaner is by far the fastest and most efficient method to safely clean these components when proper procedures are applied.
With trichloroethylene no longer available for cleaning PCBs, a substantial amount of posted information relates to cleaning, soaking and scrubbing using high purity alcohol, flux removal sprays and special biodegradable solvents. These manual processes are time consuming, could damage delicate components, can be environmentally unfriendly, and there is no guarantee that contaminants have been completely removed from complex PCB configurations. An ultrasonic cleaner such as the Elmasonic S series available from Tovatech is the practical answer to producing thoroughly clean high performance PCBs.
