Werner, -What guidelines do you use for stacking? ie resistors on caps, caps on resistors. -Is stacking better than booking the components? -What about flux trapped between the parts? I have run into stacking as *common practice* for the first time recently and am totally in the dark. Given the design boundary conditions (5# package with 10# of components) I can understand it, that doesn't mean I like it. I still want to build the best "bad" design I can.
