I have just recently returned from a trip to Japan in which I was guided through many of the largest capitive PWB fabrication facilities in the country. I need not say who these companies are, but let me just say that most of the multilayer boards I saw, were going into the electronics that we use virtually every day of our lives. Why is the majority of what I saw being done with additive techniques? My understanding is that throughout N. America and Europe we are using subtractive technology. I realize that there are the few companies who have licensed SLC etc., Does anyone have a feel for what percentage of North America and Europen PWB fabs employ Additive technologies? Does anyone feel that there is major trend towards additive? How many years away is it? Do we really need to employ additive to get to 0.003"/0.003" or 0.002"/0.002" in high volume production? I see an obvious difference in markets here. I am trying to figure out how geographical areas can employ such different techniques. (Maybe readily available cash and long term investment strategies is the real difference?) I would appreciate any input that I get. Thanks much in advance, Jim Morrison
