Precious Plate provides specialized gold plating services designed for applications where conductivity, adhesion, and surface integrity are critical. Our wire bondable gold processes deliver consistent bond quality and performance for manufacturers in electronics, aerospace, and advanced device industries.
Wire bondable gold plating demands more than just surface coverage—it requires metallurgical precision. Precious Plate combines proprietary electroplating processes and advanced surface preparation techniques to achieve exceptional bonding consistency. Every plating run is controlled for purity, thickness, and grain structure, giving customers a repeatable, high-performance finish.
Each project is engineered for application-specific outcomes—balancing conductivity, cost efficiency, and mechanical durability. Our team collaborates closely with engineers to tailor our process to unique design or production requirements.
Excellent wire bondability with aluminum and gold wires for both wedge and ball bonding
Controlled gold thickness ranging from microinches to microns to meet critical application needs
Uniform deposition across selective areas, minimizing material waste and cost
Exceptional purity with minimal organic contamination, ensuring high pull strength
Compatibility with nickel underlayers and other diffusion barriers
Proven reliability for thermal cycling and high-frequency electronic performance
Our gold plating process integrates advanced deposition control with precision masking and selective plating to ensure microelectronic-level accuracy. Every step is engineered for surface cleanliness, purity, and adhesion.
The outcome is a gold finish specifically tuned for demanding wire-bond reliability in microcircuits, sensors, and hybrid assemblies.
Base materials such as nickel or copper receive chemical cleaning and activation to ensure strong adhesion.
A nickel or palladium barrier layer may be deposited to block diffusion and strengthen bond interfaces.
High-purity gold is electrodeposited using a tightly monitored bath chemistry and current density for consistent thickness.
Deionized water rinsing removes trace contaminants, preventing oxidation or residue.
Each batch undergoes cross-sectional thickness measurement, adhesion testing, and wire bond pull testing to verify compliance.
A semiconductor supplier was experiencing inconsistent bond pull strength during die assembly due to surface contamination and variable plating thickness. Precious Plate developed a tailored gold plating specification that incorporated a refined surface cleaning process and precise gold-thickness controls. After full production implementation, the client achieved a 20% increase in average pull strength and improved first-pass yield across multiple assembly lines.
