I also thought 45 degrees is used to reduce ESD, provide the best use of die space, and reduce stress on the metal with high current. Maybe all of that is a myth? Any other angle doesn't have the same benefits.
- picture 5y agoAny-angle routing may actually be better for use of space and reducing stress. I sometimes get more traces packed around a bend with any-angle. And most polymide PCBs are any-angle or at least super rounded with teardrops, having sharp transitions of any type would act as weak points.[1] ESD really doesn't make sense, maybe you meant EMI or EMC? There's nothing particularly special about 45 degrees other than the ease of modeling [1]: Some macbook trackpad, note the polymide/flex substrate and rounded tracks. This isn't fully any-angle like what TopoR does though https://commons.wikimedia.org/wiki/File:Apple_MacBook_Pro,_model_A1278_-_trackpad_-_connector-8395.jpg https://commons.wikimedia.org/wiki/File:Apple_MacBook_Pro,_m...
