Q: What are your thoughts on electroless copper vs. direct metallization?
A: Both get the job done! Electroless copper is the more traditional method but may have some problems with its internal crystalline strength when used with stacked microvias. Direct metallization is a newer technology that has come a long way in their development and is one of the few ways to successfully metallize polyimide film for flex.
