The ENEPIG surface finish is capable of ultra-demanding requirements.

December 5, 2024 - San Mateo, California -  San Francisco Circuits, a premier provider of leading edge technology printed circuit boards, has published a new article on ENEPIG (Electroless Nickel Electroless Palladium Immersion Gold) PCB Surface Finish. ENEPIG is one of the most popular PCB surface finishes due to reduced palladium prices and its advantages over finishes like ENIG. Composed of four metal layers - copper, nickel, palladium, and gold - ENEPIG offers excellent protection against corrosion and the infamous "black pad" issue.

ENEPIG: Ideal for Demanding Requirements ENEPIG supports various package types, including BGA, SMT, wire bonding, and press fit. With a thin gold layer (0.05μm - 0.1μm), it simplifies assembly and provides improved reliability and a long shelf life.

Advantages of ENEPIG:

  • Black Pad Free
  • Higher Reliability than ENIG
  • Cost-Effective
  • Lead-Free & RoHS Compliant
  • Excellent Solderability

Applications of ENEPIG: Ideal for multi-layer PCBs, high-density assemblies, and industries such as military, medical, aerospace, and high-performance devices. To learn more about ENEPIG and other PCB surface finishes, visit the full page on the San Francisco Circuits website.

San Francisco Circuits offers a comprehensive range of turnkey PCB assembly services, including design, prototyping, and production, all under one roof.
