It is used for selective plating, fancy non-restricted burried via boards, as well as for some flexible laminates. Essentially, conductive ink is applied onto a substrate by a plotter (pen or ink-jet), and the tracks are then 'beefed up' to standard thickness using electroplating. Many layers are possible and there are no restrictions on even or odd number. The cost, of course, is astronomical. >>Ahhh, memories. >Nostalgia isn't what it used to be.
