Thermal Residue Fingerprinting: A Revolutionary Approach to Develop a Selective Cleaning Solution
During the last 5 years, the processes to remove flux residues especially for lead-free and challenging geometries have demonstrated new cleaning obstacles which have to be overcome. A new methodology has been recently developed to further increase the propensity for successful cleaning. At the core of this method is the thermal identification of the residue matrix. Thermal energy changes the physical state, i.e. transitions between liquid, solid and gas phases. By taking advantage of such specific information during phase transitions, the cleaning process can be tailored to such settings, which in turn increases the cleaning success significantly.
