GOLD PLATING per MIL-G-45204, ASTM B488, AMS 2422 Advanced Plating Technologies offers a complete range of functional gold plating services including Type I, II and III purity deposits in hard, soft and duplex gold formulations. Our over seventy years of experience in providing precision barrel, rack and vibratory gold plating is currently employed in numerous industries including the medical, telecommunications, defense, aerospace and electronics industries.
HARD, SOFT & DUPLEX GOLD PLATING VARIETIES Hard gold plating (Type I 99.7% pure or Type II 99.0% pure) preferred for high temperature applications since the is commonly employed in applications where repeated alloying elements in hard gold plating can oxidize at sliding or contact wear is a design consideration, such elevated temperatures. Soft gold plating is commonly used as in interconnect pins, contacts or springs. Hard gold is for low-load connector applications between 10 grams to commonly used when contact pressures are greater than 50 grams of contact force. 50 grams. APT offers a high-purity hard gold plating that is Duplex gold plating incorporates layers of both hard and soft alloyed with a small amount of nickel to produce a hardened gold. Duplex gold is commonly used to reduce the porosity deposit with a refined grain structure. APT’s hard gold of the deposited layers, maximizing corrosion performance plating is optimized for hardness, wear and solderability, per mil thickness. Duplex gold systems can reduce the providing an outstanding functional hard gold. overall gold consumption required to pass porosity tests Soft gold plating (Type III or 99.9% pure) is commonly used such as the nitric acid vapor test, providing significant where the highest of gold purity is required for soldering, economic advantages. APT also offers several unique pore- wire bonding, biocompatibility, high temperature or high sealing technologies (PST) to further enhance the corrosion corrosion resistance applications. A soft gold deposit performance of the gold layer. APT’s technical sales group provides an extremely pure gold layer, which maintains can assist with engineering a duplex gold system to include the low hardness and high corrosion resistance of gold specific layers, thickness of deposits and underplates consistent with its elemental form. Soft gold plating is required to meet specific design requirements.
GOLD PLATING SPECIFICATIONS The three most common gold plating services certified by Advanced Plating Technologies are MIL-G-45204, ASTM B488 and AMS 2422. Our company can provide Type I, II and III gold deposits per these industry standards.
