Abstract Most fluxes and their flux residue are corrosive, presence on the surface of assemblies may cause reliability concerns due to electrochemical migration. This study firstly refers test method IPC-TM-650 2.3.32D 2.6.15C requirements in J-STD-004A evaluate flux-induced corrosion corrosivity residue. Then thermogravimetric analysis is used level after soldering under identical conditions. ...
WARNING COSMEGEN (Dactinomycin for Injection) should be administered only under the supervision of a physician who is experienced in the use of cancer chemotherapeutic agents. This drug is HIGHLY TOXIC and both powder and solution must be handled and administered with care. Inhalation of dust or vapors and contact with skin or mucous membranes, especially those of the eyes, must be avoided. Avo...
Choline chloride + levulinic acid deep eutectic solvent is studied as a suitable material for CO2 capturing purposes. The most relevant physicochemical properties of this solvent are reported together with the CO2 solubility as a function of temperature. The corrosivity of this solvent is studied showing better performance than amine-based solvents. A theoretical study using both density functi...
Tinplate cans were used to study if electro-activated brine solution (EAS) is more corrosive than conventional one by ICP analysis. The results showed different effects of EAS on cans, alone or filled with product. Acidic EAS (pH 2-3) and Redox +900 to +1200 mV highly reacted with the cans. The concentrations of Zn, Fe, and Cu in the solution were 0.028, 28.81, and 0.022 ppm, respectively. No S...
