In the past, flux and heating were the typical method to be used for soldering, but special new generation solderers, as Greatcell Energy’s ultrasonic one, introduce a new type of soldering, based on heat and ultrasonic vibrations. The induced cavitation effect replaces usage of flux as well as the cleaning process, since there are no exhaust fumes and pollution. By combining this device with particular solder alloys (purchasable from Greatcell Energy), the customer can solder on almost of all the materials, for example glass, ceramics, aluminium, molybdenum etc. (except for low melting organic substances). The Greatcell Energy ultrasonic solderer can be mounted with tips from 1 mm to 4 mm adjustable by 0.5 mm unit, with a 45° tapered cut or straight form.
