The Perfect Copper Surface
Nov 12, 2015 | Eric Stafstrom; Technic Inc, Garo Chehirian; Tech-Etch.
In order to provide the functionality in today’s electronics, printed circuit boards are approaching the complexity of semiconductors. For flexible circuits with 1 mil lines and spaces, this means no nodules, no pits, and excellent ductility with thinner deposits. One of the areas that has to change to get to this plateau of technology is acid copper plating. Acid copper systems have changed in minor increments since their introduction decades ago. However, the basic cell design using soluble anodes in slabs or baskets has for the most part remained the same. Soluble, phosphorized, copper anodes introduce particulate and limits the ability to control plating distribution....
