Amino Acids as Activators for Wave Solder Flux Systems: Investigation of Solderability and Humidity Effects

Using machine learning algorithms to predict failure on the PCB surface under corrosive conditions

“…Among these contaminations, Glutaric acid is more aggressive due to its deliquescent relative humidity (DRH) value and high solubility in water film due to higher dissociation constant followed by succinic acid, and adipic acid [84,85]. Glutaric acid has DRH in the range of 80-87%RH for a temperature range of 25-60 • C, while values for adipic and succinic acid for the same range of temperature are around 83-99%RH and 81-95%RH, respectively [54,82,83,86]. Table 3 displays the snippet of the experimental data results with the average of LC and failure state in each condition gathered by such kinds of the graphs from Fig.…”
