ISIG - Autocatalytic Silver with Immersion Gold

 


Technic ASIG - Autocatalytic Silver Immersion GoldTechnic’s ISIG process is a significant advancement over traditional immersion silver. It is the best conductive metal for 5G applications, performing exceptionally well up to 300 GHz. Unlike other processes, ISIG provide extremely gentle ion exchange with the copper and provides superior surface sealing, effectively preventing copper diffusion to the surface—a phenomenon known as creep corrosion. To further enhance protection, an immersion gold deposit can be applied, which shields the silver similarly to how it protects in ENIG processes. Immersion gold offers robust protection in harsh environments, especially in applications where solder mask is not used. It does match and surpass ENIG performance under creep corrosion testing.
