Selecting the Best-Suited Plating Materials for Peak PCB Performance

Plating on circuit boards involves applying a thin layer of metal to the surface of a PCB to enhance its electrical conductivity, improve solderability and provide protection against corrosion. This process typically utilizes electroplating or electroless plating, where metals are deposited onto the PCB through chemical reactions or electrical currents. The resulting metal layer facilitates reliable electrical connections while contributing to the overall durability and performance of the electronic components housed within the PCB.

Choosing the appropriate plating materials for PCBs optimizes performance and longevity. Besides enhancing electrical conductivity and solderability, these materials protect against environmental factors such as moisture and corrosion. Understanding the properties and applications of various plating materials can help manufacturers ensure their PCBs meet industry standards, such as the Restriction of Hazardous Substances, and perform reliably in diverse applications.

• Copper:Copper is popular in PCB platingdue to its excellent electrical conductivity. It works well for through-hole plating — where it coats the interior walls of drilled holes for multi-layer connections — and in surface plating, where it enhances conductivity on traces and pads. Although copper is highly versatile, it can also oxidize in some applications, so additional protective coatings are often applied to prevent degradation.
• Silver:Silver is an excellent choice for plating printed circuit boards because it offers superior electrical conductivity, ensures efficient signal transmission and minimizes resistance in high-speed applications. Silver also provides excellent solderability, making it ideal for creating reliable connections between components during assembly. Additionally, the material's ability to shield against electromagnetic interference (EMI) enhances the performance and reliability of PCBs in various electronic devices.
• Electroless nickel immersion Gold (ENIG):ENIG plating combines a layer of electroless nickel with a thin layer of immersion gold on top. This process provides excellent corrosion resistance and solderability while ensuring a flat surface finish ideal for fine-pitch components. ENIG is practical for high-reliability applications — including telecommunications and automotive electronics — due to its ability to prevent oxidation during storage.
• Electroless nickel electroless palladium immersion gold (ENEPIG):ENEPIG is a more advanced plating process that adds a palladium layer between the electroless nickel and immersion gold layers. This configuration enhances the overall thermal performance and provides superior protection against oxidation compared to ENIG alone. ENEPIG is especially beneficial for applications requiring high reliability and durability — like military or aerospace — because it allows for excellent wire bonding capabilities while maintaining compatibility with lead-free soldering processes.
• Hard gold:Gold plating offers excellent conductivity, corrosion resistance and solderability, making it ideal for high-performance PCB applications. It is a common method for high-frequency circuits, connectors and components where reliability and performance are paramount. Its non-oxidizing nature ensures stable connections over time, reducing the risk of failure in critical electronic systems.
• Soft gold:Soft gold plating is valuable in PCB manufacturing because of its exceptional wire bonding capabilities and superior ductility. Its malleability is ideal for applications in testing or thermal cycling that require flexing or repeated connections. Although soft gold is typically more expensive than some alternatives, its excellent conductivity and wear resistance make it especially suitable for critical applications like aerospace or medical manufacturing.
