...Toshihiro Miyake; Masaru Ishida; Satoshi Inagaki Purpose The paper aims to focus on lowering the soldering temperature of ionic compound free soldering using 9,10‐dihydroanthracene as a hydrocarbon flux. Design/methodology/approach The ability of 9,10‐dihydroanthracene to reduce cupric oxide...

..., and dicyclopentadiene to reduce cuprous or cupric oxide was investigated. The applicability of hydrocarbons as ion free flux reagents was experimentally examined. The hydrocarbons were applied to the soldering of pre‐oxidized copper electrodes under practical conditions. Findings A 9,10‐dihydroanthracene was found...

..., a synthetic generic flux mixture of dibasic acids in both a solvent‐ and water‐based carrier, and sodium chloride. The protective properties were monitored using three complementary techniques: surface insulation resistance measurements, sequential electrochemical reduction analysis, and diffusion...
