The purpose of this paper is to introduce a new class of surface finishes as an alternative to current final surface finishes.
This new finish utilises nanotechnology and is based on a new formulation of the “organic metal” (OM).
The final surface finish is an approximately 50 nm thin permanent layer, consisting of a complex between the OM and silver (Ag). Panels finished with OrmeSTAR™ Ultra show excellent solderability in spite of a low‐layer thickness and therefore offer significant advantages over existing surface finishes.
This new finish has proven to be a competitive alternative to current final finishes with excellent properties for soldering applications. The new nanotechnology can also significantly improve the environmental and economical consequences of solderable surface finishing.
