10 The PCB Magazine • January 2017 sal surface finish," namely ENIPIG (electroless nickel/immersion palladium/immersion gold). This detailed report—including ample test data—has also been recorded as a webinar and can be viewed by clicking on the link near the end of the article. In keeping with our policy of having a few general interest items for those chemistry- phobes out there, we have no less than three columnists weighing in on the U.S. presidential election—in vastly different ways. IPC President John Mitchell starts with a discussion on how the Trump presidency and potential policy shifts may affect the electronics industry. He is followed by guest columnist John Hasselmann, IPC's VP of Government Relations, with a discussion on corporate tax policy and possible changes that may come about with the new administration in Washington, DC. Regular columnist Barry Lee Cohen com- pares the "fake news" from this past presiden- tial campaign to the potentially false news that can and probably does occur within and about your own company. Barry also provides some concrete advice on how to keep the communi- cation lines open so news and other informa- tion can be quickly disseminated—and any false "news" can be immediately combatted. IPC APEX EXPO 2017 happens next month (see our calendar of events) and what better time to have our magazine focus on new tech- nology—our topic for February. We expect there to be plenty for you to read about. You can sub- scribe now and have The PCB Magazine deliv- ered to your inbox every month, giving you a head start on all things PCB. PCB Patricia Goldman is a 30+ year veteran of the PCB industry, with experience in a variety of areas, including R&D of imaging technologies, wet process engineering, and sales and marketing of PWB chemistry. Active with IPC since 1981, Goldman has chaired numerous committees and served as TAEC chairman, and is also the co-author of numerous technical papers.

Following this is a study of immersion gold processes—some of that R&D work I mentioned earlier. Don Gudeczauskas, et al, of Uyemura International, present a fine research paper on a comparative study of three immersion gold processes, looking at both solderability and wire bondability. Lest anyone think that wet processes have no effect on electrical test, Gardien Services' Todd Kolmodin is here to set the record straight with a look at the challenges that plating and surface finishes present to electrical test. RBP Chemical Technology's Michael Carano is Mr. Plating himself, and he gives us a detailed look at some of those things you might tend to overlook or perhaps take for granted in your acid copper plating process. Rather than talk about controlling the typical constituents, Mike looks beyond at tank parameters and the sur- rounding process steps. We are fortunate to have another R&D article, this one by Ron Blake, et al, of MacDermid Enthone Electronics Solutions. They get into another relatively new area for copper electroplating, the filling of through-holes with copper. Next, our own Pete Starkey reports on a MACFEST development project on a "univer- EVERYTHING OLD IS NEW AGAIN
