Choosing the right surface finish can determine the success or failure of your design, especially for MIL-spec or high-frequency applications. In this webinar, Jose Garcia, Field Engineer at Uyemura USA, explores both conventional and emerging final finishes, examining their chemistry, reliability, and impact on signal performance.

The session begins with widely used options such as ENIG, ENEPIG, and immersion silver, comparing their cost, durability, coplanarity, and potential failure risks like hyper-corrosion and creep corrosion. It then moves into advanced finishes including ENEPIG-Thin Ni, RAIG, EPIG, EPAG, ISIG, and DIG, evaluating their suitability for fine line designs, signal integrity, and next-generation packaging.

Jose also presents a side-by-side insertion loss comparison to help you make informed decisions for RF, aerospace, or high-speed digital designs.

What you'll learn:

• Understand the strengths and weaknesses of ENIG, ENEPIG, and immersion silver
• Learn how ENEPIG-Thin Ni and RAIG address insertion loss and corrosion challenges
• Explore nickel-free options like EPIG and EPAG for better signal integrity
• Review comparative insertion loss data across multiple finishes
