【For communication equipment】Au-Sn alloy plating bath Dine Gold Star V
High-density implementation reliability supported by Au-Sn alloy plating with excellent solder wettability, Dain Gold Star V.
In the telecommunications equipment industry, as high-density implementation progresses, there is a demand for reduced contact resistance at electrical contacts and high connection reliability to ensure stable communication and signal transmission even in harsh operating environments. Particularly in terminal and connector components, good solder wettability and stable coating quality are essential for maintaining product reliability. The Au-Sn alloy plating bath Dain Gold Star V can be used under a wide range of working conditions and supports the manufacturing of highly reliable components. It enables barrel plating of micro components, resulting in a uniform eutectic alloy composition in the plating film. 【Usage Scene】 Due to its non-oxidative properties and good bonding characteristics, it is suitable for high-temperature bonding materials. 【Effects of Introduction】 - Improved connection reliability.

basic information
【Features】 - The melting start temperature of the alloy plating film shows a stable value of 280±1℃ across a wide composition range (Au: 66-87 wt%). - The anode uses an insoluble anode of platinum-plated titanium, which shows almost no oxidation degradation of Sn and has excellent long-term stability. - The plating appearance presents a gold color and luster as the gold content in the film increases from the eutectic composition. - Potassium cyanide is used as the gold salt, and it is a low-cyanide plating bath (pH 5.5) that does not contain other free cyanide compounds. - The film composition can achieve a wide range of compositions by controlling the metal concentration ratio in the bath, in addition to the eutectic composition of Au/Sn=80/20 (wt%). 【Our Strengths】 The Daiwa Chemical Group develops unique chemical businesses in niche markets that major manufacturers do not engage in, under the spirit of "San-Sou." The value of the Daiwa Chemical Group lies in its unique technology development that does not imitate others, bringing new products to the world.
