Shenzhen yugashon Surface Technology Co., Ltd. soft gold production line, through the engineering and technical personnel overtime, only after a week of planning, preparation, test, acceptance, was formally put into operation in October 12, 2014.

 

 

 

Soft gold, as the name implies, is relative to the commonly used gold cobalt, gold and nickel alloy coating, usually hardness can reach 150-220 mv. Because it contains different proportions of other metals, the hardness of the gold plating layer is increased, so it is called hard gold. Hard gold is characterized by high hardness, good wear resistance, good brightness, but relatively low ductility and poor weldability. It is not suitable for occasions such as bonding, gold wire, and so on.

 

 

 

Soft gold, because it does not contain other metal components, the purity of up to 99.99%, the hardness of only about MV80, can meet the hardness of gold and welding line special requirements. At present, the bonding of SMT and LED industries needs this soft gold especially.

 

 

 

Because of its super high purity, soft gold can meet the requirements of high temperature and no color change. Hard gold is usually more than 350 degrees, lasting 15 minutes will be red and black phenomenon, and soft gold can reach 800 degrees do not change color, in the glass packaging industry can greatly facilitate the construction process, improve quality and efficiency.
