Immersion Silver

With the pending lead-free legislation impacting PCB manufacturing on a global scale, 

the immersion silver process is rapidly gaining popularity as the lead-free surface finish of choice. 

While ENIG presently has a larger market share, over the past 12 months more immersion silver process lines have been installed in PCB facilities than any other finish. 

Immersion silver has a controlled thickness of 5-12 micro inches and a shelf life of at least 12 months. 

Silver is compatible with most assembly processes, is cost advantageous, and with its increased popularity, is becoming more commonly available.
