Reassessing Surface Finish Performance for Next-gen Technology, Part 2

03/04/2024 | Frank Xu, PhD and Martin Bunce of MacDermid Alpha, and John Coonrod of Rogers Corp.
The introduction of 5G/6G has created a growing demand for faster rates of data transfer and operation at higher frequencies, pushing signals to travel toward the outer edges of conductors. As a result, the surface finish applied over the copper circuitry is now gaining more attention.

Reassessing Surface Finish Performance for Next-gen Technology, Part 1

06/26/2023 | Frank Xu, PhD and Martin Bunce of MacDermid Alpha, and John Coonrod of Rogers Corp.
Over the years, various surface finishes have been successfully utilized, namely organic solderability preservative (OSP), immersion silver (ImAg), immersion tin (ImSn), electroless nickel immersion gold (ENIG), and electroless nickel electroless palladium immersion gold (ENEPIG), as solderable finishes for PCB and package substrates. All these surface finishes have their pros and cons, with no single finish being suited to all applications. As system designers continue to respond to new performance demands, it can be noted that ENIG/ENEPIG finishes have endured as a leading choice in many advanced applications where reliability is prioritized over cost.
